Happy

Happy (ハッピー) is an Exceed from Extalia, a member of the Fairy Tail Guild and of Team Natsu, and one of the main protagonists of the story.

Appearance
Happy is a small blue Exceed with a white underbelly. He has a rectangular head, with pink ears, big black eyes with small, thin eyebrows, and white cheeks marks near to his tiny whiskers (two in each side of his face). Happy has a triangular nose, that leads to semi-round upper lips on the sides. Happy's body is rectangular too, and being an Exceed, it has an structure that allows him to walk erect unlike normal cats. Despite having no thumbs, Happy is able to hold things. He has a long tail, that's white in the end, that can be used to hold things too. Happy is usually seen carrying around a green backpack, where he keeps food and items that can be used on battle. This backpack also covers his green Guild Mark. When using his Magic, he can grow a pair of large, feathered, angel-like wings that allow him to fly around and carry others. Happy usually doesn't wear clothes, the only few times were during the Fantasia Parade, to disguise himself in Edolas, and when his parents gave him clothes.

Personality
Despite his small stature and eccentric look, Happy is very loyal to his teammates and fellow guild members and has a fairly large knowledge of the magic world (on some cases, more than Lucy and Natsu). Given that he was around Natsu Dragneel since his birth, Happy often emulates Natsu in his actions and responses. He is quick-witted and cheeky, especially to Lucy Heartfilia; however, Happy sometimes shows his little bit of dark nature, especially when making a comment on the devastating aspects of the magic of his comrades. He loves fish and he doesn't like dogs (except for Plue). He offers a comic relief with his catchphrase, "Aye!". Happy believes that Lucy and Loke are a cute couple and tends to roll his tongue when he teases Lucy about it. He holds a strange attraction to Exceed like himself and drools on Loke's shoulder when he finds out that Loke is a lion. Happy has also developed a strong affection towards Carla, another Exceed who at first blows him off, but then begins to respect him.

History
Years ago, before Happy was born, he was taken away from his parents, Lucky and Marl by the queen of Extalia, Shagotte, to carry out the Dragon Slayer assassination plan, although they were actually sending him to Earth Land for him, along with all the other Exceed eggs, to escape a future disaster in Edolas.

Natsu found Happy's egg in the East Forest of Magnolia Town. Natsu then took it back to the guild where he and Lisanna raised it together. One night Elfman took it to keep it warm and the next day when he brought it back, it began to hatch and out popped a cat with wings. Happy's first word was Aye. Natsu gave him the name "Happy" after Lisanna pointed out the change of the atmosphere from anger to happiness after Happy hatched. Despite everyone else seeing him as a cat, Natsu thought he was a dragon.

Macao arc
Happy was first introduced when he arrived in Hargeon Town with Natsu Dragneel, who was suffering from immense motion sickness. After dealing with Natsu's motion sickness, they found the man named Salamander, who was really Bora of Prominence. There they met Lucy Heartfilia, a traveling Mage who paid for their meal as thanks for freeing her from an illegal Charm Magic Bora was using.

After finding out that Bora claimed to be the Salamander from Fairy Tail, they went to the harbor to rescue Lucy and to stop Bora from ruining Fairy Tail's reputation. While Natsu dealt with Bora, Happy escaped with Lucy, but he soon ran out of Magic Power and they plummeted into the ocean. Lucy summoned her Celestial Spirit, Aquarius, to blast Bora's slave ship back to the shore, after finding her lost Gate Keys. Natsu defeats Bora, and the group escapes after being discovered by the Rune Knights.

Once they arrive at Fairy Tail, Lucy joins the guild. Then, Happy accompanies Natsu to rescue Macao Conbolt after he failed to come back from his mission on Mt. Hakobe. Lucy joins them much to Happy's confusion. At the mountain, Natsu and Lucy begins to argue but they were interrupted when a Vulcan kidnapped Lucy. Natsu came to rescue Lucy but he was thrown down a cliff. Then, Happy saves him. He watches as Natsu battles and defeats the Vulcan who turns back into Macao. The Macao and the team almost fell from a cliff again but they were saved by Taurus. After taking care of Macao's injuries, the team head home, where Macao was finally reunited with his son, Romeo.

Daybreak arc
When Lucy finally finds herself a place to stay, Natsu and Happy pay her their very first unannounced visit. After Lucy explains all about Celestial Spirits and shows them how she makes a contract with the spirit, Plue, Natsu and Happy trick Lucy into forming a team with her to destroy the book, Daybreak, in Shirotsume Town.

When they got to Shirotsume Town and met the client, Kaby Melon, they found out that the reward was no longer worth 200,000 but 2,000,000 Jewels. After Lucy's failed attempt to infiltrate the mansion as a maid, they broke into the mansion, quickly defeating the maids, and found their way into the study, where Natsu found the Daybreak book. Everlue soon arrives and summons the Vanish Brothers to eliminate them. Lucy realizes that there is some secret inside the book and tells them to stall the enemies while she reads it. Duke Everlue goes after her leaving the Vanish Brothers to deal with Natsu and Happy but Natsu tells Happy to go after Lucy as he will take care of them himself.

Happy arrives to see Everlue binding Lucy and slams Everlue's face with his feet to free her. He then watches as Lucy battles with Everlue and listens as she explains some parts of the secret of the book. Lucy summons her Celestial Spirit, Cancer, Happy is overjoyed and thinks that Cancer is going to say kani (crab) at the end of his sentences but ends up disappointed as he says ebi (shrimp) instead, to the point of asking Lucy to de-summon him. Then, Everlue reveals himself as a Celestial Spirit Mage as well and summons Virgo, that came along with Natsu. With their combined forces, the team was able to defeat Everlue and Virgo.

The team then heads back to their client's house where Lucy reveals the secrets of the book. They refuse any reward and Natsu figures out that their client is not rich and went home to Fairy Tail. As the team heads home, Happy and Natsu realize that Lucy is writing her own novel and tease her about it.

Lullaby arc
As Happy, Natsu and Lucy talk about Dark Guilds with Mirajane, Erza Scarlet returns from her mission, bringing the horn of demon she subdued as a souvenir and indirectly causes Natsu to act like Happy. Erza looks for Gray Fullbuster and Natsu and asks them for help, much to everyone's surprise since Erza is considered the strongest female Mage in Fairy Tail.

The next day at the station, Gray and Natsu are bickering as usual. Lucy introduces herself to Erza and explains that Mirajane wanted her to tag along. Natsu then tells Erza that he would only accompany her if she promises to battle him when they return, to which she agrees. Whilst on the train to their destination, Erza explains that she had overheard something about a sealed Magic called Lullaby and a powerful Mage named Erigor's involvement with it. Erigor was part of a Dark Guild called Eisenwald and considering the illegal nature of such a guild, she planned to march right into the guild and find out what it was up to. Unfortunately, in the process of her elucidation she and the others accidentally left the motion sick Natsu on the train.

Happy helps stop the train by pulling down an emergency stop signal lever at the directive of Erza and goes to follow the train. After they are reunited with Natsu, they learn that Natsu had a confrontation in the train with a member of Eisenwald, Kageyama, Natsu told them he had a strange kind of flute. Lucy then pipes in at this moment, saying that she had only heard about it in books, but that it might be the "Death Lullaby" flute.

Eisenwald take over the Oshibana train station and the group force their way in quickly, encountering Eisenwald and fighting them. Erigor, however, has other plans and flees the scene with Gray and Natsu in hot pursuit. Erza and Lucy are left behind to fight the rest of the members with Happy accompanying them. Erza, however, defeats all of them by herself but one of them escapes and Lucy and Happy tasked to go after him. When Lucy and Happy lost track of the Eisenwald member, Lucy says they should just return to Erza but such a scary prospect is feared by Happy after Erza had told them to "go after him" forcing the two to continue. The two reconvene with the others just as Kageyama had been stabbed by Karacka, a member of his own guild.

Unable to figure out how to escape from the air barrier surrounding the train station which Erigor had cast to trap them in, Happy abruptly reveals that Duke Everlue's Celestial Spirit Virgo had given him her key to give to Lucy. Using Virgo's diver Magic they escape the train station. Happy helps Natsu catch up to Erigor on a rail bridge by using his maximum speed, but this wears him out. During the fight Natsu gets enraged by his inability to hit through Erigor's Storm Mail, and Happy notices that Natsu's increased fury affects the temperature of his fire which in turn causes Erigor's wind to flow towards him. So to further nullify Erigor's wind, Happy makes Natsu more angry by saying that he should just leave it to Gray. This infuriates Natsu enough to enable him to destroy Erigor's wind and defeat him.

Erza and company, alongside an injured Kageyama, arrive but Kageyama suddenly makes a break for it with the flute to Clover Town where the Guild Masters are having a meeting and plans to kill them. Chasing after him, they arrive and see Kageyama with Makarov and were about to go to him when they where stopped by guild masters Bob and Goldmine. They see that Makarov has persuaded Kageyama not to use the Lullaby's Magic. The flute itself starts to talk and transforms into a demon. Everyone panics but Gray, Erza and Natsu fight the demon and manage to defeat it, destroying the Guild Masters' Meeting Building in the process causing the team and Makarov to make a hasty exit.

During Erza and Natsu's promised battle, Happy rescinds his bet on Natsu's victory to Erza's after she pulls out her Flame Empress Armor. However, the conclusion of their fight is not seen as Erza is arrested by the Magic Council for property damage, among other crimes. However, they are both set free the next day.

Galuna Island arc
After Natsu and Erza's return to the guild, Happy stole an S-Class request poster so that he, Natsu and Lucy could complete it. Lucy refused at first, telling them to leave, until she noticed that the reward included an Ecliptic Zodiac key and ran after them. However, Gray chased after them at the Master's orders and caught up to them in Hargeon town. Mentioning Erza's wrath at disobeying the rules, Happy tries to make it sound like Natsu and Lucy forced him to steal the request poster. One of the sailors that had refused to sail them to the cursed Galuna Island reversed his rejection when he notices Gray and Natsu fighting with their Magic. Natsu knocks out Gray while he is distracted and drags him onto the boat. Their sailor then vanishes and although Happy checks to see if he had fallen into the water he is nowhere to be found. All that is rendered irrelevant when a large wave hits their boat and washes them ashore. Gray then agrees to help and so they go towards the the island's village and meet its mayor, Moka, who asks them to destroy the moon.

Deciding such a task is impossible, they instead investigate the island's forest and get attacked by a gigantic mouse which they defeat and in the process locate an abandoned temple. Natsu, commenting on the decayed floor, begins to slam it with his foot causing it to crumble and hurtle them downwards into a cavern, also making Happy almost swallow a bone he had found. Lucy saves him from choking by pulling it out his throat. In this cavern they discover the frozen demon Deliora along with three Mages: Sherry Blendy, Yuka Suzuki and Toby. Gray explains to the others what Deliora is: it is an immortal demon that destroyed the Land of Isvan 10 years ago, and that it was sealed by his teacher, Ur, at the risk of her life. The group decides to wait for the moon to come out for them to see the its involvement with the frozen demon. Lucy brings out her Celestial Spirit Lyra to pass the time. Happy wants her to sing a fish song but Lucy tells Lyra to sing anything she likes. When night arrives they discover that the moonlight is hitting the demon via the ritual Moon Drip which would melt the ice. As the team is hiding, Reitei Lyon, Sherry, Yuka and Toby arrive. Retei Lyon inquires about the Moon Drip ritual and orders the other three to obliterate the village. Enraged by the order given by Reitei Lyon, Natsu jumps out from hiding and attacks alongside Gray. Natsu is frozen, and Gray tells Happy to escape with Lucy which he reluctantly does.

The two arrive back at the village and informs the villagers about the oncoming danger and that it would be a good opportunity to catch them. Happy points out that the three are probably Mages, and although they outnumber them, Mages are difficult to deal with. Lucy, however, thought of a plan. Lucy summons Virgo to make the preparations for her plan: set a hidden hole in front of the village gate for them to fall in. Happy declares her stupid, saying that it won't work on anyone, although it works on Natsu. To their surprise, the Mages come by air and try to smother the village in a cascade of poison. Happy flies Natsu up into the air to prevent this, Natsu using his Fire Dragon's Brilliant Flame to scatter the poison away from the villagers. With their plan failed, the three Mages decide to confront them from the ground.

As the Mages prepares to fight, the villagers leaves the village, carrying the unconscious Gray. Sherry and Angelica go after them, but Lucy accidentally catches onto Angelica's claw and after tickling the mouse to stop ends up crashing into the forest. Happy goes to make sure she is okay while Natsu deals with Yuka and Toby. He finds her safe after defeating Sherry but also comes across a not too pleased Erza. His attempt to escape is quashed by Erza who easily captures him, saying that they have betrayed the master, and that they are not going to get away with it.

Erza forced Happy to look for the villager and Gray's location while tied up. Erza demands that Gray come back with her to the guild but Gray defiantly resists and leaves her. Angered, she resolves to instead help them and complete the mission first, freeing Lucy and Happy. They catch up to Gray running towards the temple finding out that Lyon's intentions are to free Deliora and fight him as a means of surpassing Gray and Lyon's mentor Ur. They discover that the ruins have been tilted so that the moonlight no longer hits Deliora and are then attacked by occultists. Gray runs forward while Erza, Lucy and Happy stay behind to defeat them. They then see that the ruins are re-tilted again to its original position. After they do, they go inside the temple and hear Deliora's reviving roar. However, Deliora was long dead and it crumbles to nothing.

Back at the newly restored village (thanks to Zalty's Arc of Time Magic) Erza explains that the villagers' transformation into demons was false. She clarifies when she gets Natsu to help her "destroy the Moon" but what they really do is to destroy an amnesia-causing barrier around the island that made the villagers think they were humans when they were actually demons.

Phantom Lord arc
Returning to the guild, everyone but Lucy is displeased at Erza not letting them accept the reward of 7 million jewels. Lucy's exclusive happiness is due to her receiving the golden Zodiac key of Sagittarius, to which Happy suggests that they should sell it instead. Erza then reminds them of their punishment, believing it will surely be "that" although what "that" is not explained. That's soon put out of their minds when they discover that the guild has been attacked by their long time rival, Phantom Lord.

[[Image:Happy Fight!.jpg|200px|right|thumb|Happy's fighting with members of [[Phantom Lord]] They confront Makarov about the damages done by Phantom Lord, but he just them all on the head and tells them to just ignore it. Happy and company surprise Lucy when they welcome her to her own apartment with Erza telling them they have to stick together in case anyone gets attacked. However, this has already happened to the members of Team Shadow Gear (Levy McGarden, Jet and Droy) and when Makarov discovers this he proclaims war against Phantom Lord. Happy attacks Phantom Lord alongside most of Fairy Tail, but they are forced to retreat when Makarov loses his Magical power. Natsu overhears Gajeel Redfox and Aria stating that they had captured Lucy. He forces one of the Phantom Lord members to tell him where Lucy is with Happy rushing after him. Natsu just catches Lucy as she deliberately let herself fall from one of prison towers. Natsu and Happy then argue about what they were going to do but they stopped when Lucy tells them that it was her fault. Happy and Natsu comfort her and they decided that it was best to retreat to the guild, leaving the indignant Jose Porla.

Back at the guild, Happy and the others are surprised at the revelation of Lucy's history and comforts her when she was depressed. Just then, they feel the guild quaking and rush outside to see what the commotion is: the Phantom Lord guild is on six legs and is literally walking towards their guild. It attacks with its Magical Convergent Cannon - Jupiter but Erza narrowly stops the powerful bullet for obliterating guild rendering her incapable to fight. Jose Porla calls out, demanding that they give Lucy to him but receives an adamant refusal. In response, he tells them to quiver for 15 minutes as Jupiter reloads. Rather than wait to be destroyed, Natsu says that he's going to destroy and Happy flies him to the walking guild. Inside they are confronted by Totomaru who prevents Natsu from destroying the cannon. Totomaru's abilities cause Natsu some grief, and incites Happy to panic as the time whittles away. Natsu eventually outsmarts Totomaru and destroys the cannon.

In retaliation to the sabotaged cannon, Jose orders the guild to enter its more powerful form: Phantom MK II. Since its a vehicle it brings up Natsu's motion sickness and Totomaru uses the moment to attack with his Rainbow Fire but Gray and Elfman arrive and defeat him. Happy flies outside to see what's going on, and returns telling them that the guild has become a gigantic Mage. They decide to split up, Happy going with Natsu. Natsu says they should just go defeat Jose but Happy says that's an insane idea. Regardless, they are soon faced with the strongest of the Element 4, Aria. Aria easily dominates the fight and nearly renders Natsu's Magic void until Erza arrives and takes over the fight from Natsu. Aria decides to fight seriously and takes off his blindfold multiplying his Magical power. However, Erza manages to defeat Aria with one hit. The strain from using Magic causes Erza to collapse. She later regains consciousness in Natsu's arms, she tells him to release his power and tells him that he will be the one who will surpass her. Natsu then leaves with Happy to protect the guild and Lucy.

As Gajeel was about to kill Lucy, Natsu arrives and interferes and the two Dragon Slayers begins to fight. Happy frees Lucy and the two watch as the two Dragon Slayers battle each other. As Natsu and Gajeel's battle continue, Gajeel plays dirty and eats some metal that replenishes his strength, helping him gain the upperhand. Lucy, trying to find a way for Natsu to eat fire, summons the only spirit she has at the moment: Sagittarius whose appearance shocked Happy. However, Sagittarius says that he cannot shoot fire and the three continue to watch as Gajeel continues to beat up Natsu and makes him look at the Fairy Tail guild collapsing. Natsu decided to continue fighting Gajeel although he doesn't have the strength to fight back.

Happy shouts out that if Natsu was only able to eat fire, he will be able to fight. Upon hearing Happy's statement, Sagittarius finds a solution to create fire replenishing Natsu strength and allowing him to defeat Gajeel and destroy the Phantom Lord Guild. In a last ditch attack, Natsu he finally defeats Gajeel and destroys the Phantom Lord guild. As the Phantom Lord guild crumbles, Happy carries Lucy to safety. Happy and Lucy arrives at the remains of their guild just after Makarov defeated Jose. When asked where Natsu was, Happy simply says that he has business to do.

Taking part in the reconstruction of the guild, Happy, Gray, Natsu and Erza decide to take break to eat when Loke arrives and asks them to give Lucy her keys. When they arrive at Lucy's house, they see that no one is there. Happy finds Lucy's letters to her mother that weren't sent, then Erza finds a note saying "I will go home". They then rush after her. Upon arriving at Heartfilia mansion, they find Lucy leaving her house and is surprised to hear that Lucy's family owns the place. The team then returns to the guild.

A few days when the guild was accepting job requests again, Team Natsu became official and decided to take their first mission as an official team. While doing the request they managed to destroy half a road.

Loke arc
Noticing Lucy worrying over her little amount of money, Mirajane suggests they do a simple acting job at a theater. Happy is given the task of carrying a dragon suit that Natsu is in and they are given a week to rehearse. Their show is atrocious, makes little sense and they eventually destroy the theater but despite all this they are hailed as a success to the point that they're kept there for another week doing three performances a day.

They go out on another job and chance upon Loke after swiftly completing it. Seeing how they completed it so quickly they decide to stay the night in Hosenka Town. Natsu, Erza and Gray have a pillow fight; Lucy, fearing for her life, instead takes a walk. Happy follows her and tricks her by making her think Plue was human and could talk. Two Mages then begin to flirt with Lucy and paralyze her before she is saved by Loke. The two go back to a bar where Happy falls asleep after eating. His sleep doesn't last long as he is dragged away by the tail by Lucy who leaves off in a storm.

Back at the guild, an agitated Lucy silences Natsu and Gray's bickering, a feat only Erza could do, and Happy asks if she is upset because of his prank; she answers no. Loke's old girlfriends arrive at the guild and demand to know where he is. Mirajane states that Lucy was last with him and they all converge on her making have to make a quick escape with Happy. In her apartment she calls out her Celestial Spirit Crux to dig up anything on Loke. Gray suddenly barges in saying that Loke had left Fairy Tail. After hearing this, they all go to look for him.

Tower of Heaven arc
Shocked by the announcement that Loke is a Celestial Spirit, Lucy explains to Natsu, Gray and Happy that he is a Lion spirit which Happy thinks is a grown-up cat. Considering he can no longer spent long periods of time in the human world anymore Loke gives the four of them, as well as Erza, a ticket to a fancy resort. While at the resort's casino, they are attacked by Erza's old friends who kidnapped Erza and Happy after attacking Natsu, Lucy, Gray and Juvia.

Happy later wakes up inside the Tower of Heaven in a heavily cat-themed room and has a short conversation with Millianna and Wally before Simon arrives and tells them that Erza has escaped. Natsu manages to arrives at the room but sees no one there. He was suddenly ambushed by Wally and Millianna. The two manage to gain the upper hand in their fight against Natsu, who has a cat head stuck on him, Happy then arrives and saves Natsu from getting shot by Wally by slapping the gunslinger in the face with a cuddly toy. Natsu manages to free himself from Millianna's ropes by tricking her with his secret move: Kitty in Distress and defeats both of them using his Fire Dragon's Wing Strike.

Happy pulls off the mask from Natsu's head and listens as Jellal Fernandes details the rules of The Paradise game. After hearing Jellal, they decided to take a shortcut with Happy carrying Natsu straight to the top. However, those were against the rules and they are both struck back into the tower by Fukurou. Simon is in the same corridor they landed in and he attempts to help them escape with his Instant Darkness. Fukurou, however, can see through this and blasts Simon away. Natsu and Fukurou begin to battle each other. No one seems to gain the upper hand but Fukurou makes Natsu ride one of his rockets, and since it is a vehicle it causes him to be sick. With Natsu disoriented by the ride, Fukurou swoops in and swallows him - as Fukurou has the ability to use the Magic of a Mage he has digested. Happy tries to rescue Natsu, but Fukurou uses Natsu's power to easily overpower him. Gray then arrives and takes over the fight. defeating Fukurou and freeing Natsu. During the fight, Gray took a fair amount of damage and Simon asks Happy to take him outside the tower to recover. They flee the island on a boat along with Juvia, Lucy, Wally and Millianna and watch as the weaponized satellite Etherion strikes the tower.

Thinking that Erza and Natsu might have died, they are all highly relieved when the two of them arrive on the shore. They recover in a hotel where Natsu has been sleeping for three straight days and wakes up after Gray belittles him - but this is only for a moment. He eventually stays awake and they socialize with their previous enemies before sending them off with a fireworks display.

Fighting Festival arc
When they return to the guild they find its reconstruction complete and Cana Alberona shows them around. Makarov startles them with the introduction of two new members: Juvia and Gajeel, their previous enemies. After settling down, they sit down for a a song from Mirajane; this calm state doesn't long as the two Dragon Slayers soon cause a large brawl. A reporter comes the next day to write about the guild, ignoring Lucy throughout, and asking Happy why he's blue to which he answers "'cause I'm a cat".

A few days later, Lucy is desperately looking for jobs to pay the rent and she asks Natsu and Happy to help her out. Much to her dismay, Natsu is feeling too sick from eating the Etherion and, along with Happy, goes home to rest. As Lucy finds out, by "home" Natsu meant her home and she gets a large fright when she finds Natsu and Happy in her bed. Happy explains that Natsu's sickly feelings have happened before after he ate Laxus Dreyar's lightning. He goes on to explain about the strongest members in the guild, the strongest probably being Gildarts Clive, and then gives Lucy a flyer about the Magnolia Harvest and the Miss Fairy Tail competition that is being run alongside it which would solve all her money problems. During the competition a week later, Mirajane crushes her hopes of winning by transforming her face into Happy, much to his pleasure. It continues onwards, showcasing other Fairy Tail girls, until a member of the Thunder God Tribe, Evergreen, appears and turns all the girls to stone. Soon the other two members, Bickslow and Freed, make their entrance along with Laxus. Laxus proposes a game to find out who is the strongest in Fairy Tail, Natsu replies with much enthusiasm. Laxus is holding the girls as hostages and threatening to smash them if they don't participate or break the rules. With a time limit of three hours to find and defeat them before the girls crumble to dust, the members of Fairy Tail rush out and the Battle of Fairy Tail begins.

Happy stays behind with Makarov, Natsu and Gajeel, who are unable to escape due to Freed's enchantment. Natsu and Gajeel then try to free Erza by mostly heating her which worked because of her artificial eye that halves the effect of Evergreen's Magic. She goes out and defeats Evergreen thus freeing all the other girls. In reprisal,Laxus activates his Thunder Palace effectively holding the whole town hostage. Happy then accompanies Lucy to find the other two Thunder God Tribe members and Laxus.

As Lucy and Happy are walking when they were suddenly attacked by Bickslow's dolls. Happy was able to push Lucy out of the line of fire. Then they see Bickslow himself and the two sides begin to battle. However, Bickslow seems to have the upper hand, since even if Lucy destroys his dolls, he can control more since they are fighting on top of a toy store. Bickslow then uses his Baryon Formation attack on Lucy but she was saved by Loke who came through his gate on his own. Loke tells Lucy to stay back, but Lucy tells him that she would fight alongside him causing Happy to tease them and say that they're a cute couple. When Bickslow tries to use his Figure Eyes on them, Happy tells the other two to close their eyes since they may be turned to dolls and controlled by Bickslow giving Bickslow the opening he needs to attack them. With Loke's strategy, Lucy was able to use her whip to bind Bickslow and Loke, using his Regulus Impact, defeats Bickslow.

Laxus is eventually defeated and Happy is seen together with Natsu participating in the Fantasia Parade and along with the other members, raises his hands to tell Laxus that they will always be watching over him. After the Fantasia Parade, Happy is seen, together with Bickslow, teasing Lucy about Loke. When Lucy mentions that she feels like she's being watched, Happy tells her that she has excessive self-consciousness. Lucy ignores them and heads home to prepare for the job.

When Lucy returned, Happy is seen greeting her and asks Natsu what job they are going to take. Gray reveals that it would be to capture the escaped convict Velveno. Happy is seen surprised when Lucy leaves to head to Acalypha. Happy, along with Team Natsu, followed Lucy to the LOVE & LUCKY guild and where they are surprised to learn that she defeated the Naked Mummy Guild by herself and informs her that because she ran off, they cancelled the mission.

Oración Seis arc
Happy assists Lucy in paying the rent by helping her at a restaurant, and when they return to the guild Mirajane explains about Dark Guilds and their power over the Magical underworld. Makarov then arrives and announces that an alliance of guilds are going to take down one of the strongest three dark guilds, Oración Seis. Makarov chooses Happy together with Natsu, Erza, Lucy and Gray to act as their delegates.

After meeting all the delegated teams to fight the Dark Guild Oración Seis, Happy falls in love with the Cait Shelter's talking cat Mage Carla. Next he is seen following Wendy Marvell and Carla when Oración Seis assault the Light Team, hiding with them as the others are beaten by the Oración Seis. Brain, the leader of the group, then kidnaps Wendy who grabs Happy by accident as she was trying to reach out for Carla. Both are taken to the Oración Seis where Brain explains who Wendy is and her powers to the other members. Brain then presents a coffin to Wendy with the body of a half dead Jellal inside and implores her to heal him.

Happy tries to act as the voice of reason, explaining Jellal's past actions at the Tower of Heaven. Though hesitant through his words, Wendy revives Jellal nonetheless just as Natsu arrives. Jellal quickly knocks down Natsu and turns on Brain before leaving the cave without further incident. Natsu recovers then leaves the cave along with Happy, Carla, and Wendy. The group is suddenly knocked out of the sky by Racer who spots them while fighting Gray, the fall of which knocks out both cats. Natsu then grabs them and runs while Gray prevents Racer from going after them. Natsu takes him and the others to Erza so Wendy could heal her. When Erza runs off to find Jellal and Natsu chases her, Happy joins Carla, Hibiki Laytis, Lucy and Wendy to follow Natsu. They find Natsu stuck on a raft and are confronted by Oración Seis' Angel and her Spirits who transform into Gray and freeze Happy when he attempts to save Natsu from the raft. He is later seen thawed out, helping a weakened, and probably unconscious, Hibiki out of the water.

Happy later appears rescuing Natsu as he fell from Nirvana's true form, and flew him up to its city where he aided Natsu in fighting with the Poison Dragon Slayer Cobra in a flying battle. Using his heightened hearing against him, Natsu roars so loudly that it overpowers Cobra and knocks him out. Cobra's poison begins to affect them both and they fall to the ground. However, Cobra has quickly recovered and almost strikes a deadly blow on Natsu before Oración Seis' Guild Master Brain intervenes and shoots Cobra. Brain drags Natsu away, planning to make him his first puppet. Jura Nekis, Lucy and Gray find Happy who informs them of Brain's plans. Jura, one of Ten Wizard Saints, stops Brain and effortlessly defeats him. Carla and Wendy arrive just at that moment, Wendy's Sky Dragon Slayer Magic curing them both, and after Happy tells him about his motion sickness, that too.

Wendy rushes away, Carla with her, and the rest of them receive a message from an enemy turned ally, Hoteye, via telepathy. He tells them that the strongest of the Oración Seis, Midnight, is directly below them and that his defeat will stop Nirvana. They rush downwards but at the last moment discover it's Brain's trap. The group was saved by Jura's timely intervention who is heavily damaged by the ambush and rendered unconscious. As they try to make sure he's okay, Brain's staff, Klodoa, laments about Brain's pathetic power and that he should just defeat them himself before being captured by Natsu and slammed around. He frees himself from Natsu's grip and tells them of their plan: to destroy the Cait Shelter guild so Nirvana can never be resealed.

Klodoa begins to bash them, but abruptly stops when he feels that the Six Demons have all been defeated and that this will herald the arrival of Brain's split personality, the vastly powerful and bellicose Zero. Sure enough, Zero arrives and easily defeats the team. Nirvana then arrives at Cait Shelter and Zero orders it to attack. The powerful blast from Nirvana is however stopped with another strike when the combined efforts of the other alliance members who managed to get the Magical Bomber Ship Christina, which was shot down earlier by Oración Seis, up and working again. Hibiki, piloting the ship, telepathically tells them the details on how to stop Nirvana: destroy the six lacrima crystals in Nirvana's legs that serve as its power source simultaneously. Zero interrupts, using telepathy himself, saying that their plan is futile as he stands at one of the crystals and will prevent anyone trying to destroy it. The other alliance members desperately call on Natsu, Gray, Lucy and Happy to get up and they defiantly comply.

On the map that Hibiki has downloaded into their head, the group decided on which lacrima they are going to go to. After choosing, Happy reminds them that if they find Zero, they have to take him down themselves and that they have no backup. He then accompanies Lucy to destroy her appointed lacrima crystal, but is confused when Lucy reveals to him that she has no more power left. He later appears relieved as Gemini arrives to help them out.

After the defeat of Zero and the crumbling of Nirvana, Happy, along with Natsu and the others, tries to fight off the Rune Knights that plan to imprison Jellal, but fails as he is stepped on.

Edolas arc
After Cait Shelter is revealed to be nothing more than an illusion, he goes back home to Fairy Tail along with Wendy and Carla.

When Gildarts arrives and tells Natsu to visit him in his house, Happy accompanies Natsu, and is shocked to hear that Gildarts has faced a dragon during his quest. Gildarts then tells him to continue supporting Natsu. A few days later, he is seen wrapping and presenting a fish to Carla, but is confused and sad when she coldly rejects him. He follows her, and she tells him that he cannot protect Natsu, as he doesn't even know what he is. As he is left wondering about what Carla said, Happy crosses paths with Gajeel, who then asks him why his face has so many scratches.

After Anima swallows Fairy Tail and the whole of Magnolia, Happy is able to find Wendy, Natsu and Carla gathered together. He then listens in shock as Carla reveals that both she and Happy are beings from a parallel world called Edolas, and that they were the reason to why the whole town disappeared. He then listens as Carla goes in detail about the history of Edolas, and also about how they received a secret mission from the King of Edolas. After learning that they may be able to save the Fairy Tail members, Happy flies Natsu into Edolas using his wings, alongside Carla and Wendy. The Edolas version of Lucy then manages to catch the group sneaking around their guild, and Happy is both shocked and scared by her new appearance, even referring to her as 'Lucy-san'.

Lucy and the other Edolas Fairy Tail members quickly welcomed Natsu and the gang. Later he sees Edolas Lisanna and like Natsu, shed a huge amount of tears for seeing her again. Before he could hug her, he got kicked along with Natsu by Lucy Ashley and then asked how Lisanna could be alive in this realm. Carla later tells him that this is Edolas and that everyone here is not their friends, but different people. He later teleports along with the guild to a safe location from the Fairy Hunter, and is shocked to learn that the Fairy Hunter is Erza Knightwalker, Erza Scarlet's Edolas counterpart.

The group, along with Lucy Ashley, travels to the Louen City and finds Earthland Lucy, who apparently still has access to all her zodiac key Magic. The Earthland Magic users see that the lacrima crystal that contains the essence and Magic of the rest of Earthland Fairy Tail is under heavy guard in the Royal City and there is nothing they can do. Carla puts forward a plan where the Mages would travel through an abandoned coal mine to the royal bed chamber and use Gemini to copy the king's knowledge of the giant lacrima and how to release their friends. However, they are ambushed by Erza Knightwalker and captured. Then, much to everyone's shock, all of the soldiers bow to Happy and Carla and call them the Exceed, congratulating them on leading the Mages into the trap.

Carla and Happy meet up with other Exceeds and learn of their true mission. They were originally sent to kill Dragon Slayers but at the last minute, their mission was changed to capturing the Dragon Slayers for their unique Magical energy. Carla realizes that she completed her mission even though she did not intentionally want to and she breaks down in tears for what she has done. Carla was about to lose faith, when Happy stands up for her despite not remembering the mission or who he really is. He explains they are nobody's puppets and that they are still Mages of Fairy Tail. This makes her have a glimmer of hope and even makes her call Happy by his name for once instead of "Male Cat". Happy grabs Carla and decides that they will rescue their friends themselves, causing a rebellion against the kingdom and the guards try to capture them as they are escaping. They hide in a wooden cart to escape the guards but the cart rolls downhill and they end up on a field where they meet an unnamed exceed. The exceed recognizes them as rebels but still decides to shelter them telling them to hide in his house where he resides with his wife. As soon as things calm down all four of them have a conversation about bonds and friends. After the conversation ends, Happy and Carla make up their minds to save Natsu, Wendy, and the guild. With their confidence restored in the friendships they hold with Natsu, Wendy, and the rest of the guild, they are finally able to fly into the sky.

After returning to Edolas, they manage to save Lucy from the hands of Erza Knightwalker. Carla tries to exploit her lack of information and presents herself as Extalia's princess and a daughter of Queen Shagotte. She then tricks Erza into revealing the location of Natsu and Wendy, then tries to get her releasing Wendy and Natsu, which almost succeeds. Unfortunately, the rest of the royal guard arrives, and Pantherlily informs Erza that Carla and Happy are the "fallen" (traitors). All three attempt to escape. Carla asks Lucy if she's angry at them. Lucy is very surprised by this question and she really doesn't know for what she should be angry for. Carla said that it is their fault that she got caught in the first place. Lucy replied that they had came to save her, and she adds that she is more surprised by the fact that Carla is a princess. When Carla reveals that it was bluff, Happy comments on how it was so like her to do so.

The peace lasts for a short while though, as Extalia troops from the sky and Magic Militia from the ground surround them. Luckily, Faust decides that it is now a perfect moment to execute code ETD, which turns the Extalia troops into a giant lacrima. Shocked, Happy and Carla immediately fly away with Lucy to the West Tower where Wendy and Natsu are held. Unfortunately, they are led into yet another ambush with Erza Knightwalker and her soldiers. As Carla pleads with her to let Wendy go, Knightwalker declares that they do not need to worry as they are about to die. As she prepares to execute Carla, Happy steps in front and tells Erza that she would have to go through him first. As Edolas Erza raises her weapon to strike, her soldiers are suddenly blown away, and Happy is thunderstruck as it is revealed that their saviors are no other than Earth Land Erza and Gray.

While Earthland Erza holds off Edolas Erza, Happy and the others head towards where Natsu and Wendy are. Along the way he learns of Gajeel arriving in Edolas, and how his Dragon Slayer Magic released Gray and Erza from the lacrima. Realizing that he can do the same to the other trapped Guild members and towns people, he flies towards where Gajeel is to tell him where they currently are. As he is leaving, Lucy is worried about him leaving on his own, but Carla has faith in him and assures her that he will be fine so she doesn't not to worry. Happy finds Gajeel then takes him to where the whole guild is but before Gajeel can free the guild, he encounters Pantherlily. Happy asks why an Exceed would side with the Royal Army whilst Pantherlily states he no longer sees Extalia as his home. Gajeel has taken a liking to Pantherlily and decides to make Pantherlily his cat but wants to show who is stronger between the two, which greatly shocks Happy.

Gajeel and Pantherlily stop fighting when the Dragon Chain Cannon hits the island they're on. Happy wonders how someone could do something like destroy an entire race just for Magic. Happy helps in the attempt the stop the Lacrima from hitting Extalia with the rest of Earthland Fairy Tail and Coco. Happy is shocked when Carla and Nadi also come to help against the struggle. Happy then looks behind him and sees a bunch of Exceeds coming to help along with Wendy. Just when the Lacrima is about to hit, a last minute effort manages to stop it, but right after a line of Magic appears and the island disappears. Everyone looks on in shock at the disappeared Lacrima that is Fairy Tail. Mystogan then shows up stating he sent it back to Earthland safely. When Edolas reinforcements arrive, and Faust with the Dorma Anim, Happy states how it looks like a dragon. Happy, together with Carla, lands Natsu and Wendy to fight it. Natsu tells them to go protect the Exceeds, as he, Gajeel and Wendy take care of Faust. While riding on an Edolas creature, Erza Knightwalker shows up and blasts Coco's Legion sending it to the ground. Happy grabs onto Lucy, and Carla grabs onto Gray and Coco as they see Erza Scarlet fight Erza Knightwalker.

Lucy, Coco, Gray, Happy, and Carla fall into a forest and Lucy gets upset for Happy dropping her, but he says she is heavy. Edolas troops show up. The troops spot Carla and Happy and aim to turn them into Lacrima since they are the only two left. Gray attacks and protects them. Lucy summons Loke while Carla and Happy dodge beams of Magic, but Carla jumps in front of one to protect Happy. They start to lose when even more reinforcements arrive, but then Edolas Fairy Tail comes to the rescue and helps them fight. Happy exclaims that their feelings have helped move this world. When Mystogan starts taking all the Magic away from Edolas, the troops lose their Magic weapons and retreat. Everyone panics including Edolas Fairy Tail. Carla and Happy look around at all the panicking. Finally when all the Magic is gone, all the Earthland Fairy Tail members start being sucked into the Anima as well returning back to their home. They all say goodbye to Edolas Fairy Tail and Coco. Happy cries realizing he will never see them again.

After returning back to Earth Land, Happy is surprised by Exceeds' arrival to the said place and tried to calm down Carla, who wanted to send them back to Edolas. The Exceed Elders and Shagotte explained the truth about the "mission", including Carla's ability to foresee the future, and interpreted as her mission to eliminate the Dragon Slayers.

Happy noticed that Carla and Queen Shagotte are very alike (in fact, they are daughter and mother) and he and his father subconsciously mimicked. His mother tells him that he could go visit them anytime and Happy said that for some reason he really likes his parents' smell, which made them cry and his father yelled at him. Then he sees Pantherlily's new form and is shocked to see Lisanna while she hugged him. Lisanna revealed to be actually Earth Land Lisanna and Happy and Natsu were filled with joy. With this, he helps her back to her siblings for a tearful reunion.

Tenrou Island arc
After their return, he is seen celebrating with the guild members. He then begins to converse with Carla and Pantherlily, and watches as the guild erupt into another brawl.

Days later, Happy helps Natsu to complete various jobs in rapid succession. The day after, at the S-Class Wizard Promotion Trial Ceremony, he congratulates Natsu for being chosen to participate in the trial. Moments later, Natsu picks him to be his trial partner. After remarks from Elfman and Gray Happy declares that he is going to make Natsu a S-Class Mage for sure, and the two of them rush to train themselves. That night, as Happy calls Natsu for dinner, Natsu is brimming with confidence that he will be an S-Class Mage. Happy looks at him with admiration.

As the participants head towards the island, Happy lies exhausted from the intense heat. Shortly after, the master arrives to explain the rules of the first trial. After hearing and realizing the boat stopped, Natsu and Happy tried to fly ahead towards the island first. However, Freed used a rune on the boat, which prevents everyone from leaving for 5 min, though Levy and Evergreen were able to rewrite the rune, so only 5 teams were trapped. As soon as the rune was released, Natsu and Happy flew to the island and Natsu chose path E, out of the remaining 4, since he believed E stood for Erza and that he wants to fight her, much to Happy's confusion.

Happy and Natsu are then seen going down the E path, as Natsu calls out for Erza. Happy remains unsure if Erza really is here. Natsu and Happy realize someone's there once they see a foot come out from the darkness, and the person is revealed as Gildarts. Gildarts says that Natsu got bad luck this round and he hates holding back. Happy then says that the competition for Natsu is over, due to remembering how strong Gildarts is. He was mostly a spectator for the battle, and did not participate much. He cried when he thought that Gildarts destroyed Natsu with his Magic, and was shocked when it started to rain Mini-Natsus and was even more shocked when Natsu's confidence multiplied and chose to continue fighting Gildarts.

Natsu uses all of his known techniques, however, he only made Gildarts move from his original place. Gildarts was impressed with Natsu and was going to let him pass, but Natsu won't hear of it, saying that if he will become an S-Class Mage, he needed to beat him. Gildarts knew that Natsu was going to say that and unleashes his full power, saying that there is something that Natsu needs to acquire before becoming number one. Natsu stares with awe at Gildarts power and, knowing that he no longer stand a chance at winning, kneels down and gives up. However, Gildarts lets him pass, saying that it is necessary for an S-Class Mage to know their weakness, and warns Natsu of the tasks ahead. Gildarts then leaves, saying that Natsu will have a chance to fight him again, but for now, he needs to be an S-Class Mage. Happy and Natsu arrive at the winner's circle where Makarov briefed everyone about the other's fate and about the second part of the exam.

When the second exam started, Natsu and Happy come across Evergreen, Elfman and the Killing Mage. When the Killing Mage's power was activated, Natsu saved Evergreen and Elfman and asks the Mage who he is. Happy, Natsu, Evergreen and Elfman then noticed that the trees have all withered and realized that it was because of the Mage. The Mage seemed to know who Natsu is, however, an angry Natsu charges in and punched him in the face. The Mage seemed to be unscathed but begins to cry. Suddenly, his Magic activated but everyone was saved by the muffler that Igneel gave Natsu, making Happy wonder whether Igneel gave the muffler for Natsu's protection. After the Mage disappeared, Natsu saw his muffler and complains about it being coordinated with his clothes, making Elfman and Evergreen think that he cares about fashion. Natsu and Elfman then remembers the exam and decided to continue, Happy thinks that the Mage has no bad intentions. Natsu and Happy continues their search for the grave when they saw the signal that means enemy's are attacking. Natsu wonders whether it could be related to the Mage they fought. Natsu then says that they will strike back to anyone picking a fight with Fairy Tail.

Natsu and Happy arrives at the site of Wendy, Mest, Lily and Carlas battle against Azuma. Azuma has already vacated the scene. Natsu interrogates Mest but stopped when Wendy pointed out that he was from the council. Carla was explaining who their enemy was when they notice Caprico with his Jet Pack using his Magic to send down Grimoire Heart Guild members. When the Grimoire Heart guild arrives on Tenrou Island, Happy helps Natsu fight the enemies. After Zancrow arrives to fight Natsu, and burn his allies to death, Happy goes over to the wounded Carla, Pantherlily, and Wendy. When Zancrow hits Natsu with his fire, and after Natsu realizes he can't eat it, Happy shouts for Natsu in a worried way with disbelief. Zancrow then burns Wendy and the cats for their annoying commentary.

After Natsu and Makarov's battle with Zancrow has concluded, Happy is seen with the rest of the cats and Wendy worrying over Natsu and Makarov's condition. Happy explains how the scarf got turned black, which makes Pantherlily wonder if that guy really is Zeref. When Natsu wakes up, Happy is delighted. He tells Natsu that Wendy fixed up his muffler and his clothes. However Natsu picks up a familiar scent of a former enemy that he fought on Galuna Island and walks off, despite the protests.

Happy followed Natsu as the latter continue to follow the scent. With a slip on a leaf, Natsu slid down a slide, along with motion sickness. Landing in front of Zeref, the ground below Natsu quickly birthed a tree. Sitting on the top of the tree was Ultear, and Natsu noticed that she's the one with the scent. Ultear then wonders if he was also after Zeref, to which Natsu replied that he isn't, and will not forgive any of them. The two of them started to fight, but with Ultear being serious, Natsu was forced onto the defensive side of the battle.

As Natsu and Ultear continues their battle, Lucy and Kain Hikaru arrives. When Natsu asks Lucy what she was doing there, Happy remarked that Lucy was sent flying over in their direction rather ungracefully, to which Lucy asked if there was a "cool" way to be sent flying. Happy then stated that now Natsu had two opponents, and Natsu said that they had added an extra member themselves. He then said that he would put the trial and hold and that they should form a team, Lucy said that it was nostalgic, Happy said that it made him think of when they first met, and Natsu remarked that he was all fired up. Happy threw his hands in the air as Lucy and Natsu high fived and they both remarked that they should defeat them.

After Kain agrees to handle Natsu and Lucy by himself and Ultear takes her leave, the fourway battle between Natsu, Lucy, Happy, and Kain begins. When Kain believes victory is at hand Happy steals his doll. Kain knocks Happy with one blow and tries to recover his doll but Natsu takes it instead, trying to counterattack, however Kain acts faster and delivers a powerful blow to Natsu which ends with him crashing and half-buried by rocks. Unable to move on his own, Lucy tries to summon Virgo, but has no more power left and is subsequently captured and tortured by Kain. Natsu asks her to run, but she refuses, prompting Kain kill Lucy by crushing her head. Before he can do it, Natsu uses the doll to manipulate Lucy, on a counterattack in which Kain takes a brutal beating. Further boosting Lucy with his own Dragon Slayer Magic, Natsu gives Happy the doll so that he can use the speed to further power Lucy. Happy then grabs the doll and flies around using max speed which increased the flame on Lucy. He then made Lucy deliver Kain a brutal kick to the face finally defeating Kain.

Happy is then seen when he asks Natsu to break the boulders he is stuck in with his flames, to which Natsu responds that that is a good idea. Once Natsu is free they look over and notice that Zeref is no longer there, and Natsu remarks that something is getting in the way of his scent.Lucy then raises her leg and says she has to look for Cana, and Natsu asks her why she was raising her leg. She then begins to chase after Happy who has taken Mr. Cursey from Kain and using it to control Lucy, but Natsu says that it is time to take a nap. Lucy then says, while bending Happy with Mr. Cursey after plucking one of his hairs and trying to apologize to her, that they can't because she's worried about Cana and they must search for Zeref.

They then begin to speak on Grimoire Heart's goal and Natsu says that since they laid a finger on Makarov that they wouldn't leave the island. Lucy then realizes that they must have a ship somewhere anchored on the island and asks Happy to go search for it, but he replies that he is out of Magic power. Natsu then states that they should get back to where Makarov is resting and that they would have Lily or Carla take care of it.

He along with Lucy and Natsu arrive at the site where Makarov is resting, and when Doranbolt arrives Natsu asks he went, and Lucy says that it is Mest of the Council. He then tells Lucy that his name is really Doranbolt. Wendy begins to ask him something but Doranbolt tells her not to worry because he came there to help them, which surprises Happy and Carla. He then says that with his powers everyone can leave the island, but Happy and the others refuse. Despite Mest's attempts to convince them otherwise they all decide to stay on the island and fight.

Happy is then seen with Wendy, Lucy, and Natsu as they try to convince Doranbolt to stall the council while they defeat Grimoire Heart. Later, he, along with Wendy, Natsu, Lucy, and Carla, is beaten in one blow by Grimoire Heart member Bluenote Stinger. Happy is then seen lying on the ground is shock at the strength of Bluenote.

Happy is surprised when Cana Alberona arrives and fights Bluenote. He watches as Cana was overpowered by Bluenote, and Gildarts arrives just in time to stop him much to everyone's relief and delight. After Gildarts' arrival he orders everyone to get away, and the force from Gildarts and Bluenote clashing sent Happy and the others flying. After realizing that they'd only be in Gildarts way Happy and the others left. Later when Azuma destroyed the Great Tenrou Tree, Happy is seen collapsing along with the other members of Fairy Tail.

After Erza defeats Azuma, Happy and the others return to the camp and discover their injured friends. Wendy tries to heal them using her magic but Carla and Happy disagree with the idea since she already exhausted her Magical Power and suggest that she rests for a while.

After sitting around at the camp, Natsu is ready to go. Happy convinces Lucy to come with them to defeat Hades. The attack team of Natsu, Wendy, Lucy, Carla, and Pantherlily, later meet up with Erza and Gray on their way to Grimoire Heart's airship. Everyone then stands there and faces Hades.

After Hades goes into his airship, Natsu tells Happy and the cats to search around the airship for a power source to make sure the ship will not take off mid-battle. As the cats crawl through the vents, Happy looks down below and sees something, claiming "it was alive", leaving the cats in shock. After the cats drop down, Grimoire Heart members spot them, so Pantherlily holds them off, as he tells Happy and Carla to stop the power source somehow, thus they start pulling chains and hitting the machine to stop it. Carla and Happy successfully destroy the power source just in time, so Hades's Magic stops working, so Natsu can defeat Hades. The power source, turned out to be Hades's real heart, which was the source of his Magic, and of his longevity.

After the battle ends, Happy and Carla run out of the airship being chased by Grimoire Heart members. They all flee once they see Makarov, the Thunder God Tribe, Gajeel, Levy, Mirajane, Elfman, Cana and Lisanna come. Everyone returns to camp. Happy and Carla sit and congratulate each other on a job well done. Happy later goes fishing with Natsu and Gildarts, but they are interrupted by Lucy and Cana. After Lucy gets Cana and Gildarts alone, Lucy, Happy, and Natsu watch as Cana reveals Gildarts the be her father, which shocks Happy and Natsu.

Everything is interrupted when the dragon, Acnologia lands on the island and starts its rampage. Makarov uses his Titan and takes the dragon head on, and tells the rest of Fairy Tail to leave, and to not disobey his final order. Happy runs next to Natsu with the rest of the guild, crying. Happy returns with the rest of the guild to help Makarov defeat Acnologia. The dragon eventually takes to the sky though, and prepares its final attack to destroy the island. All of Fairy Tail holds hands as Tenrou Island is destroyed by Acnologia's Dragon Breath.

X791 arc
When Acnologia unleashes his Dragon Roar to destroy Tenrou Island, Mavis Vermilion converted the bond and friendship of the Fairy Tail members in order to save them by using Fairy Sphere. However, due to the nature of the Magic, Happy and the other members of Fairy Tail were trapped inside the sphere, frozen in time. After seven years, the other members of Fairy Tail, with the help of the Trimens, discover the island and rescue Happy and the others. They then sail back to Magnolia and are welcomed back by Romeo.

The return of the missing members starts a celebration that lasted the whole night. During the party, Romeo reveals his Magic to Natsu and Happy who recognize it to be the same as Totomaru's. Happy then asks Pantherlily about the Exceed and wonders if they are worried about them. Pantherlily tells him not to worry, as Exceed perceive time differently. After the party, Natsu and Happy return home and realize they have no savings or food. They follow Lucy to the Love & Lucky Guild to see her father, in hopes that he will lend them something. However, the trio is informed that he died a month ago.

The trio then returns to Magnolia, Natsu and Happy feeling miserable for Lucy. Upon reaching Magnolia, the trio separates. Natsu and Happy head back to the guild and take a job. The duo then heads towards Lucy's apartment in order to ask her to accompany them but finds themselves face to face with Lucy's Landlady. She asks the two to take it easy on Lucy and reveals that payment for Lucy's rent arrived that morning. Hearing this, Natsu and Happy turn to go on their job, saying goodbye to Lucy and promising to bring her back some gifts. Lucy, however, tells the two to wait for her and the trio leaves to do their job.

After watching Natsu have a hard victory against Max, Happy, Natsu, Lucy, Gray, Wendy and Carla head towards Porlyusica's house in order to ask her for a way to raise their Magical Power. However, Porlyusica refuses to talk to them and tells them to head back home. During their way back to Magnolia, Wendy voices out that Porlyusica has the same flavor and voice of Grandeeney. Hearing Wendy words, the group tries to contemplate the meaning behind the mystery. As the group talk, Porlyusica appears behind them and reveals that she is the Edolas version of Grandeeney who came to Earth Land by accident. She then gives Wendy a stack of papers that gives her direction to use two different Sky Dragon Slayer spells.

The group then returns to their guild and is informed by Romeo about the Grand Magic Games. Hearing that the winner of the tournament will be crowned as the number one guild in Fiore, the group immediately agrees to take part in it, forcing the opposing older members to agree. With three months left before the tournament starts, the Fairy Tail members separates into groups in order to raise their Magical Power.

During their training, the group of Team Natsu, Juvia, Levy, Wendy and Carla are visited by Virgo who asks to help her save the Celestial Spirit World since it is in the crisis of destruction. The group immediately agrees to help and goes to the Celestial Spirit World. Arriving at the gates of the world, the group finds themselves face to face with the Celestial Spirit King who reveals that the crisis was merely a ruse for them to have a reason to invite them for a welcome back party. After a day of partying, the group returns to the human world, only to find out that one day at the Celestial Spirit World equals to three months at the human world, leaving them with only five days until the tournament.

While the group laments on the fact that they spent three months partying at the Celestial Spirit World, a pigeon arrives with an invitation, asking the group to head to the West Woods. The group follows the invitation and finds themselves face to face with Jellal, Ultear, and Meredy. The three Mages reveal that they saved Jellal from prison and formed the independent guild, Crime Sorcière, with the goal of eradicating all evil done by Dark Guilds and Zeref. The trio then asks the group for a favor relating the tournament and proposes a way to raise their Magical Power via Ultear's Arc of Time.

When Ultear begins the process on Natsu, Happy is worried about Natsu because of the amount of pain he is in. Later that night, when Jellal, Ultear, and Meredy leave, Happy draws a broken heart in the sand with a stick mocking Erza's relationship with Jellal and she kicks him and sends him flying.

In the last day before the starting of the Grand Magic Games, Happy arrives in Crocus alongside the rest of Team Natsu. He, Natsu and Lucy later went to see the city, where they meet Sabertooth's Mages. Happy gets surprise when he sees Lector and Frosch, and the two begin to mock him. Returning to the lodging, Happy expresses his grudge against them, swearing revenge.

Suddently, the Pumpkin Man appears, much to Happy's surprise, announcing the Preliminary Event of Grand Magic Games. However, due Wendy's absence, Elfman replaces her, and the Team heads toward the Sky Labyrinth while Natsu tells Happy and Lisanna to search for Wendy and Carla, which Happy replies with a cheer. Searching in Crocus's streets, they find Wendy's bag in the ground.

Found in the bushes, Wendy and Carla are brought to Domus Flau's emergency room, what makes Happy extremely worried about Carla. Happy them goes to the stadium's grandstand alongside the other Fairy Tail's memebers to cheer for their friends. Suddently Mavis Vermilion appears near them, shocking the entire Guild. Pantherlily joins them too after the entrance of Team Fairy Tail B, stating that Gajeel got very strong, which Happy replies that Natsu too. Happy stands alongside of Pantherlily for the rest of the Games.

During the first Event of the Games, Hidden, that Gray took part, he showed a new form of using Ice-Make, surprising Jet and Droy, then Happy states that is a result of hard training. Near to the end of the event, Rufus uses Memory-Make to hit the opponents, what makes Happy amazed. The event then ends, with Fairy Tail's teams in the bottom of the ranking.

For the Battle Portion of the first day, Lucy Heartfilia and Flare Corona are chosen to the first battle. Happy, alongside the other Fairy Tail's members, was too focused on the battle that they didn't notice Flare using her Magic to take Asuka Connell as a hostage. Blackmailing Lucy, Flare starts harming her, surprising the audience, but Natsu figured out Flare's plan, and neutralizing it, what surprise them even more. This allows Lucy to turn the table, then she starts casting Urano Metria, but the spell is suddenly erased, resulting in Lucy's defeat, much to Happy's anger.

The second match of the first day was a quick, resulting in Ren Akatsuki's win against Arania Web. Before the third match, Happy wonders if one of the selected, Orga Nanagear, is strong like Rufus. The answer comes shortly after the beginning of the battle, as Orga defeats War Cry with a single blow, scaring Happy. The final battle is win byJura Neekis against "Mystogan", which keeps Fairy Tail Teams in the bottom of the ranking. During the rest of First Day's, Happy alongside the Guild gathered at a bar to commemorate their "crushing defeat". Despite this, the Guild Members' mood was good, as Happy cheers for Natsu when states that he'll win in the next day.

The Second Day's event, Chariot, involves running on chariots, which leads the Dragon Slayers Natsu, Gajeel and Sting to get extremely nauseated. Happy comically says that Gajeel and Sting are "taking Natsu's character", as Natsu was the only character so far known to have motion sickness. When Stings asks why did Fairy Tail enter the Games, Natsu replies that they're doing it for their comrades, which deeply moves Happy and the other Guild Members
