Accelerator

Accelerator (一方通行 (アクセラレータ) ) is a main protagonist of the Science Side in the Toaru Majutsu no Index series.

He is the most powerful esper currently residing in Academy City. First appearing chronologically in Toaru Majutsu no Index as an antagonist, he later becomes the primary male protagonist of the Science Side after being defeated by Kamijou Touma. He is a member of GROUP since Volume 13 of the light novels, when he was forced to join after hearing how it was the best way for him to protect Last Order. As the most powerful esper of Academy City, his existence and powers are tied to the plans of Aleister Crowley, the founder of Academy City, alongside Kamijou Touma.

Appearance
Accelerator appears as a skinny teenager and has pale skin, moppy white hair and red eyes. This is caused by his ability, as it blocks ultraviolet rays, thereby preventing his body from producing melanin. His ability also has an affect on his hormones, as he stated in the manga series it was because of his power he has "...this genderless body" but evidence is hinted and stated throughout the series he is a boy. His only example was he told Last Order he has a thin, girlish waist. He also seems to have an affinity for black and white-themed clothing. When he is enraged or excited (such as when fighting a strong or amusing opponent e.g Kamijou Touma in the Sisters Arc) he breaks into a wide grin and laughs, giving him an almost maniacal appearance.

Personality
Due to the potential of his ability, Accelerator has been targeted by assassins and researchers throughout his life. As a result, he believes only in power and trusts no one. While fighting, he invokes fear and has a sadistic tone. He willingly joins the SISTER experiment to gain a reputation as the most powerful and feared psychic so that no one would dare be foolish enough to challenge him and won't hesitate to kill any who get in his way. The Sisters' memories of his behavior during the experiment may suggest that he is, in a way, a pacifist; because his power won't disappear, the only way he sees an end to the fighting is to be so strong and sadistic that no one would dare to raise a finger against him. He even seems to attempt to frighten the Sisters out of fighting or otherwise encourage them to refuse their battles.

After meeting Last Order, he strives to protect her (although he states he does not like her company, he tolerates her). He saved her from Amai Ao's plot and from being pursued from the Hound Dogs. He treats Index in a similar fashion, such as when he buys her lunch while searching for Last Order and by protecting her from the Hound Dogs. By Volume 19, he has mellowed out to the point that he actually lectures a child in order to prevent him from getting himself killed after a hostage situation.

His attitude towards Touma was hinted at throughout the novels after Volume 5, when it is shown that he both idolizes and is slightly jealous of Touma's heroic personality, and is outright shown when he and Touma finally come to blows in Volume 20. By comparison according to Heaven Canceler, Touma and Accelerator are very similar, but their methods are like opposite sides of a coin; Touma is able to protect his loved ones without killing and is able to stand by their side, while Accelerator protects his loved ones through violent methods and even admits that he is unable to stand by Last Order and Yomikawa's side. Deep down, he is someone that aches for the light, as shown when Yomikawa was able to walk up to him and slowly take a gun from his hands before he tried to finish off Kakine after their fight, and later when he refused to hurt a Misaka WORST clone and tried to heal her wounds after she tried to kill herself.

Aiwass has also commented on the differences between Touma and Accelerator – stating how Accelerator craves for the wholesomeness of being a 'hero' like Touma, even to the point that he declared himself evil because he believes he cannot reach that level. He is someone that tries hard to redeem himself.

Accelerator was shown to often underestimate his enemies earlier in the series, which led to his loss against Touma. However, after nearly being killed by Kihara Amata and fighting Komaba Ritoku, he no longer underestimates his enemies. This fact is noted by one of the terrorists in Hula Hoop in Volume 19 as possibly being the most terrifying thing about him: he always uses exactly how much force he needs to in order to defeat his enemy: no more and no less. If he ever underestimated his enemies, it would have given them an opening they could have exploited, but since he didn't, he simply wiped them out.

In Vol 22 After-word the author states what Accelerator want most is not a lover but a family, and states Last Order is like his child he has to take care of. Also in Vol 22, Misaka Worst said half-jokingly she wants the same fatherly treatment as he gives to the other Misaka clones.

Background
Much of his past is unknown, but Accelerator mentions that he once had a "normal name" which has yet to be revealed. The novels state that his last name consists of two kanji and his first name three. Accelerator as a child couldn't fit in with the other children due to his powers, harming those that tried to get close to him. Despite what bullies, adults, or city security tried, they were powerless against his vector changing ability. This has made him something of a loner and distrustful towards other people. After some time, Accelerator was discovered by Kihara Amata, who trained him in how to control his powers and influenced him enough for Accelerator to adopt his personality.

Accelerator's ability made him the subject of an experiment attempting to create the first Level 6 psychic; according to the city's best supercomputer, Tree Diagram, this feat could only be achieved by killing Misaka Mikoto, the 'Railgun', 128 times. However, because it was impossible to create 128 of these 'railguns', due to the 'Level 5 Mass Production Plan' only being capable of producing a sub-standard clone of Mikoto at a power of Level 2-3, a substitute plan was arranged where Accelerator would have to kill 20,000 Misaka clones in a variety of methods. He willingly joins the experiment to gain a reputation as the most powerful and feared psychic so that no one would be foolish enough to challenge him ever again. By the beginning of the Sisters Arc (index), Accelerator has already killed the first 10030 Misaka Clones and during the course of the arc, kills clone 10031 before the experiment is ultimately stopped.

Later it is revealed he originally wanted this reputation simply so that no one would ever get hurt trying to attack him, resulting in their own destruction, though as he went deeper into Academy City's dark side his goals slowly became more and more twisted.

Sisters Arc

 * Main article:Sisters Arc

August 20th.

In one of the battles, he kills a clone in a vicinity near Kamijou Touma, this event causes Touma to intervene in the experiment. Touma uses the logic that if the weakest Level 0 (Touma) can defeat the strongest Level 5 (Accelerator) then the experiment will fall apart, as the prevailing condition that Accelerator is the strongest esper would be nullified.

Accelerator is later seen in another fight against Misaka 10032, where he tells her that he wants to gain a status that is beyond simply being the strongest in Academy City - he wants to attain Level 6, so that challenging him would be an unimaginable thought- even a sin. They are interrupted by Kamijou Touma who challenges him to battle just as Accelerator was about to finish the clone off. Initially seeing Touma as a weakling, he later panics and is confused as to why Touma was capable of blocking his abilities. Eventually, Touma is able to beat Accelerator using his street fighting skills, exploiting Accelerator's physical weakness (due to the nature of his power, he always defeated his foes with a single hit and never took damage, he therefore had no experience in hand-to-hand combat as his opponents could never reach him), and ending the experiment.

Three Stories Arc

 * Main article:Three Stories Arc

August 31th.

After his defeat, he takes on a more heroic role, protecting a small girl named Last Order- a Misaka clone numbered 20,001. In later volumes, he becomes weaker along with his powers due to Amai Ao shooting him in the head, damaging his brain. This forces him to use a cane and to compensate the lost parts of his brain with a choker-type electrode conected to the Misaka Network, the battery of the electrode can only allow him to use his power for 15 minutes. This time frame is eventually extended to 30 minutes after GROUP's support technicians modify it.

Kazakiri Hyouka Arc

 * Main article:Kazakiri Hyouka Arc

At the end of the arc Accelerator is seen sleeping in a hospital room with Last Order sleeping on a chair next to his bed.

Tree Diagram Remnant Arc

 * Main article:Tree Diagram Remnant Arc

{C}{C}September 14th.

Accelerator sneaks out of the hospital he was in to destroy the remnants of Tree Diagram, as a request by Last Order. He meets with a weakened Musujime Awaki who carries a remnant of Tree Diagram, irritated by the fact that he was forced to help out and his opponent was only a "stupid looking third rate" like her. Although Awaki is aware of Accelerator's weakened state and believed that she could match him now, Accelerator is unperturbed. Simply replying that him being weaker doesn't make her any stronger, he quickly defeats her and destroys the remnants of Tree Diagram, ensuring that it will never be rebuilt.

Academy City Invasion Arc

 * Main article:Academy City Invasion Arc

September 30th.

Accelerator, along with Last Order, leaves the hospital and moves into the apartment of the Anti-Skill Yomikawa Aiho as a request from her friend Yoshikawa Kikyo. Accelerator was reluctant since having him next to her would put her and others in high danger because of his enemies.

Later on, after a short nap, he realizes Last Order has gone missing, making him search for her. During that time, he bumps into Index, not knowing her connection with Touma, and even treats her with food - costing him all of his pocket money. They separate as Index spots Touma amongst a crowd and runs towards him, just as Last Order runs to Accelerator. Because he wasn't in the mood to search for her again, he tells Last Order to keep quiet but she trips, almost crying because of some scraping on her hands and knees. Accelerator goes for some medicinal bands at a nearby pharmacy, but upon returning he is hit by a black van from the black-ops known as Hound Dogs, who were under the orders of Kihara Amata, the man who discovered his powers. Amata's orders were to retrieve Last Order, but he decides to beat Accelerator to a pulp first, as he knows his powers inside out, including how to turn Accelerator's redirection against him and even negate his wind-based powers. In desperation, Accelerator blasts the captive Last Order away from the Hound Dogs with a wind blast, then manages to escape Kihara and his men by way of a chance distraction by an aloof Index, who came looking for him to return a pack of tissue he gave her. Just as Kihara launches a homing missile at Accelerator and Index's getaway van, he is interrupted by Vento of the Front's arrival, letting the two escape.

Accelerator, considering Index dead weight, decides to drop Index off at the hospital where Heaven Canceler works, misleading her into thinking he needed a replacement battery for his choker electrode and having her fetch it (no replacement exists). He then sets off to kill Kihara, crush the Hound Dogs and save Last Order, but decides to just focus on saving Last Order after a jarring conversation with Heaven Canceler, who reveals to him that he knows far more darkness than even Accelerator has encountered. Accelerator attempts to shake off the pursuing Hound Dogs temporarily, but eventually resolves to force Kihara into re-evaluating his priorities away from Last Order (and towards eliminating him) by wiping out his Hound Dogs. Unfortunately, after wiping out two whole squads with psychological tactics alone (conserving his remaining 7 minutes of active esper power), he snaps and goes all-out at a taunting, fleeing Hound Dog who manages to seek aid from two surviving Anti-Skills, and ends up on the Anti-Skills' wanted report.

After receiving a call from Touma (whose voice he fails to recognize) regarding Last Order's whereabouts, he gets a lead from a call from Kihara, who now has Last Order captive, and breaks into one of of Academy City's board directors' homes, digging up Kihara's (and Last Order's) whereabouts. He attacks Kihara's compound, but runs out of electrode charge without being able to bring him down, yet ultimately kills him as he first "awakens," having an epiphany right as he was to be finished off. This is symbolic because the god that Accelerator`s power just happens to resemble is Osiris, the Egyptian god of the dead.

Terra of the Left and the Document of Constantine Arc
October Xth.

Academy City put Accelerator in charge of the operation to subdue the problem with Terra of the Left in Avignon. Hundreds of HsPS-15 AI suits and eight HsB-02 planes were sent and proceeded to tear apart the city, using speed to create vacuums after the plane's path and sending iron sand into the vacuum to make it explode. Accelerator tells them to change their plans to bomb just the Palais des Papes instead of bombing whole Avignon, the order being approved when the pilot he was with checked with the higher ups.

At the end, Itsuwa sees Accelerator in the middle of the scorching flames caused by a HsB-02. Accelerator is speaking with one of the higher ups of Academy City on the phone, telling them to send troops to come search for Terra's corpse and run to DNA Tests to see if he's really dead. It is unknown if he notices her or not as she is covered by the steam. Accelerator leaves soon after to a deeper part of palace. Itsuwa say that she finds Accelerator, who is able to stand in the middle of such flames, to be even more terrifying than Terra.

Battle Royale Arc
October 9th.

After Accelerator joins GROUP he finds himself involved in a fight between the underground organizations where he fights the second strongest Level 5, Kakine Teitoku. When his fight was about to end, he pointed a gun at Kakine and almost pulled the trigger, but Yomikawa ran in and interfered. She told Accelerator that he doesn't need the gun, and that she will do whatever it takes to pull him out from the darkness. Accelerator was determined to eliminate anyone that gets in his way in order to protect the ones he wants to protect, including Yomikawa herself, but Yomikawa was eventually able to take the gun away from him because deep inside, Accelerator still hopes for the light. After Yomikawa took the gun, Kakine impaled Yomikawa with his wings first, then pressed her against the ground with an invisible attack, saying that it wasn't that easy and that he and Accelerator didn't need her help. Kakine also did this out of spite, thinking if Accelerator, someone that even surpasses himself in 'Evil' is nothing more than a person that still has attachments on the side of light like a weak, normal person, then what does it make himself who has lost to that kind of halfhearted "evil?" That's why he tried to kill Yomikawa, for the sake of his pride that if he is to be defeated then at least let the one that defeated him be the ultimate "evil."

Then, Accelerator went berserk, full of anger, frustration and hatred lamenting he still can't protect the people he cares. Then he truly "awakens", gaining Black Mist Wings and attacked impaling Kakine with Kakine's own wings and then ripping his body apart. Stated in the novel that the wings are an expression of his AIM field, similar to Kakine's own "Dark Matter." Crowley even comments offhandedly to Heaven Canceler on the process of Accelerator's awakening, stating that "The process of downloading the data of the AIM field, onto the vector controlling device (Accelerator) has finally been completed." This seems to imply that turning Accelerator into an Artificial Angel has been Crowley`s plan all along, and goes hand in hand with creating a Level 6, a being equal to God.

DRAGON(≠Angel) Arc
October 17th.

After the aftermath of the events in Volume 15, he is hired along with the other members of GROUP to take a rogue group called "Spark Signal" in Academy City. After Accelerator wipes out their main force, they find info on DRAGON, a mysterious force, and when Accelerator tried to get close to the 5 remaining members of Spark Signal to gain information on DRAGON, the bodyguard of the Director, Shiokishi killed the remaining members and told Accelerator to stay out of Shiokishi's businesses if he doesn't want to regret it. He runs into Takitsubo Rikou lying in a bad state when Hamazura Shiage, who misunderstands Accelerator's intentions, arrives. Shiage tries to fight him but doesn't stand a chance, yet Accelerator leaves them both after watching how determined Shiage was and because Rikou caused him to feel compassion.

After he left the place, GROUP negotiated with Director Oyafune to help Accelerator take down another director that was after GROUP. When Shiokishi was defeated, he remarks he 'unfortunately' does know the truth about DRAGON, and it might have been better if he didn’t know in the first place. When the 4 of them asked him what DRAGON was, he replied “DRAGON is everywhere" and then everyone else, including GROUP save Accelerator, were knocked unconscious. When the director exclaimed the one behind them that did this wasn’t Fuse=KAZAKIRI like he thought, he was knocked out as well, with a voice somewhere saying "of course not, its DRAGON."

In front of Accelerator appears Aiwass, a higher dimensional super-being, the true author of the Book of Law and Crowley's mentor summoned to the physical plane of existence by Aleister himself. Aiwass keeps Accelerator conscious out of curiosity. Aiwass then explains that when AIM entities like herself (although Aiwass' gender is unspecified, it appears female) are manifested, Last Order is heavily strained and may die/collapse if left untreated. Accelerator got cut in half after he used his cane to jam Aiwass's AIM field and foolishly tried to attack her. However, in the end he shut down the Misaka Network to weaken Aiwass, shooting the core, but still Aiwass was unscathed, with the additional defenses programmed in by Aleister. Aiwass said, "That’s such a pity," before defeating Accelerator.

Accelerator headed to Russia after Aiwass suggested not even Heaven Canceler can heal Last Order. The only one that can save Last Order now is "Index Librorum Prohibitorum." Accelerator crushed his cellphone, erasing his last link to Yomikawa, Yoshikawa, GROUP and anyone else he ever had a link with and then began his search for Index to help Last Order from her weakening state, since he managed to save Last Order last time when she last collapsed while sustaining Fuse=KAZAKIRI.

Fiamma of the Right and World War III Arc
October 30th.

While riding a train carrying military supplies to Russia, Accelerator spends a few moments talking to a barely conscious Last Order. This conversation is cut short when 10 unmanned Powered Suits attack the train, Accelerator covers Last Order's eyes with a handkerchief before engaging them. It seems the goal of machine soldiers weren't Accelerator or Last Order, but various parchment with spells on them. Accelerator easily annihilates the forces Academy City sent troops for and than studies the parchment.

As of Volume 20, he is currently in Russia, where he has a brief encounter with some Russian mages, and some of Academy city's new streamlined, high-speed power suits. It is also during this encounter where we learn that his ability not only works on magic (although incompletely, as the magic is dissipated instead of redirected) but also on teleportation as well. Accelerator also has an encounter with one of the new Level 4 Misaka clones, dubbed Misaka WORST, where he learns of Crowley's plans to make a new network with the new line of clones, and eliminate Last Order who has now become obsolete. Despite being far more powerful than the clone, he is at a disadvantage since he cannot bring himself to hurt another clone after the Level 6 experiment, and sustains minor injuries. Misaka WORST then proceeds to taunt and mentally traumatize him, telling him about the Sisters' hatred of him, and how Last Order's emotions for him are false. She ultimately forces Accelerator to choose between protecting Last Order or upholding his vow to never hurt another Misaka clone.

This causes Accelerator to have a mental breakdown, losing all reason when he awakens, and goes berserk. He proceeds to beat Misaka WORST into the ground, becoming even more cruel and barbaric than his old personality from the days of the experiment. Despite having lost all faith in humanity, he still saves her when she attempts suicide as a way of showing the scientists who doubted him, that he does have the capacity to save people (alternatively, he only did it to annoy the ones who thought up this plan, telling them they've failed in their calculations). He then continues his rampage in front of an injured Misaka WORST, which she notes that being around him and seeing this state causes her to feel a lot of fear and regret for pushing him too far.

Later he sees Kamijou Touma passing in a military convoy along with Elizerina's forces. Accelerator, angry that the supposedly "invincible hero" is not willing to help Last Order in her time of need, attacks him out of the blue. He starts by causing a massive explosion that knocks down Touma, who miraculously survives. Accelerator then realizes that frequent battles must have given Touma some kind of supernatural instinct, an incomplete form of precognition for sensing AIM fields in some way, and thus reacting to the minute movements of his opponents.

Touma then proceeds to get up and exchange words with Accelerator, showing the Accelerator both idolizes and is jealous of Touma and his heroic personality because he cannot attain such a personality himself. Touma rebuts Accelerator's hero-villain ideals, stating that heroes are not necessary and telling Accelerator to realize that choosing good and evil and being heroes and villains are all unimportant - what really matters is the desire to protect someone.

Accelerator then summons 100 wings and strikes Touma with them, only for Touma to use his Imagine Breaker to grab one of his empowered wings and throw Accelerator off-balance. Touma then proceeds to punch Accelerator in the face, knocking him down. The second defeat at the hands of Touma triggers another big change in Accelerator's mentality, as Touma shattered Accelerator's ideals and the power of the black wings that he gained by submitting himself to the dark side. Accelerator's villainous rationale that had been his pillar of support was "killed" by Touma.

Touma also uses his Imagine Breaker to stabilize Last Order, although it was only a temporary fix, and then leaves him a note informing him to look for "Index Librorum Prohibitorum" to inquire about the lambskin Touma saw Accelerator had, though Accelerator mistook it for a note telling him to look for Index if he wants to save Last Order, since he heard about Index from Aiwass. Accelerator is later seen in a convoy traveling along with Elizarina's troops searching for a way to heal Last Order.

He currently has possession of a lambskin document sought after by Academy City, and may turn the tide of the war. He acquired it from a Russian military convoy he was hiding in, and when Academy City forces attacked, he thought they came after him while it was for the lambskin document. Accelerator then took the report, thinking of using it as a bargaining chip for Last Order's safety - if Academy City wants it so badly, they would mobilize the same forces they'd use to fight a Level 5 esper then it should be useful.

In Volume 21 the lambskin is revealed to be the last piece for Fiamma to fill the gap between Index's knowledge of all magic and allow him to access magic of Divine origins. Because of this, Gabriel attacks him and he is forced to defend himself. He and Fuse=KAZAKIRI, after initially fighting each other, were able to defeat Gabriel due to the combined efforts of Acqua of the Back and Kamijou Touma; taking away 50% of Gabriel's power and removing Gabriel from Fiamma's control respectively.

To save Last Order, he and Misaka WORST analyzed Index's song, that was stored on the Misaka Network, using his vector abilities to understand it and perform the spell. He was severely damaged by it, but completely cured Last Order. Soon after, Fiamma blasted a huge amount of telesma from the Star of Bethlehem as a last ditch effort to complete his goals. Sensing the attack coming, Accelerator fully "awakens," changing his wings from black to white and gaining a halo over his head. After saying goodbye to the recently cured Last Order, he went to intercept the telesma. He succeeds, and was later picked up by an Academy City retrieval unit. {C}{C}After the retrieval, he forcefully negotiates with Academy City to free everyone from the darkness.

Freshman Attack Arc
Accelerator reappears after the war with Last Order and Misaka WORST all living in Yomikawa's apartment with an honored deal of releasing those on the Dark side of the Academy with the Board of the Directors. This peace didn't last long as members of the "Freshmen" wanted to eliminate him and Shiage out of jealousy. The attack ends with the return of Touma and the final events of the first novel have him, Touma, and Shiage conversing on Magic and the state of World War III.

Homecoming
The meeting of three protagonists is moved to Touma's house as suggested by Leivinia Birdway, after temporarily separating from Touma, who got drunk, he is surprised to see one of his former teammates Musujime with Touma and a dozen other girls. After mid-way through the discussion on Magic, he is surprised once again on meeting another former teammate Motoharu, who gives thanks for being released as a spy for Academy City, only to be annoyed at Last Order and Misaka Worst appearing out of nowhere.

When Radiosonde Castle appears in the sky over Academy City, Accelerator uses his newly acquired knowledge of magic and Feng Shui to locate the crystal "transmitter" which was calling the flying fortress.

Sisters Arc
Accelerator first appears in Toaru Kagaku no Railgun, where during another session of brutally killing a Misaka clone, he meets an enraged Misaka Mikoto who tries to get revenge on him after she witnesses him killing Misaka 9,982. However, Mikoto is powerless against Accelerator due to his abilities. He later figures out that she is the original Misaka Mikoto and becomes disappointed that although both are Level 5's, Mikoto is very weak in comparison to him, and, wanting to speed-up the experiments, opts to kill her. He is prevented from doing so by the arrival of several Misaka clones, who tell him that he should follow the protocols, as killing Mikoto would cause discrepancies in the calculations. Accelerator accepts this explanation and leaves Mikoto alone after telling her his name.

Accelerator reappears briefly in his battle against Misaka 10031, where Mikoto accidentally sees how he reverses the clones' blood with his vector powers on a monitor. Later, he reappears in another experiment with the clones, this time he has to defeat Misaka 10032, but is interrupted by the arrival of Touma. Many of the scenes featured has the fight featured in Accelerator's perspective and shows as well the beginning of the Experiment with a younger self. Right before Touma delivers the final punch, he questions what he has been doing this whole time.

Sometime later, he appears again, already linked up to the Misaka Network. He is asked to demonstrate in the Daihasei Festival along with other fellow Level 5's, which he refuses and nearly kills the man confronting him on the matter.

Abilities
Accelerator's ability creates a thin field of AIM around him, which allows him to modify the vector values of anything he touches. After the events of Volume 5, his brain has been damaged, and he has to rely on a choker-type electrode that connects him to the Misaka network. The network allows him to use language, as well as making up for his lost ability to make calculations, although it is stated that it's only half of what he once had. When using the network in esper mode, the battery of the electrode only lasts fifteen minutes. That changes in when he joins GROUP and its technical team cranks his time up to thirty minutes. He does not need the network to use his abilities when in an awakened state.



He is shown to be far stronger than any other Level 5 in Academy City, being able to easily defeat the "Awakened" #2 Level 5 esper Kakine Teitoku without awakening himself. It should be noted that this fight took place after Accelerator's brain was damaged and he was forced to start relying on the Misaka Network to do his calculations, which reduced him to having less than half of his former calculation abilities. The nature that Accelerator`s power belonged to the Aeon of Osiris until the vol. 22 when he passed to the Aeon of Horus.
 * Redirection: He can change the vector values of anything by touch; for example, he kills a Sister clone by reversing the flow of blood inside her body after putting his finger inside her wound. Furthermore, this ability is automatic, so projectiles like bullets or explosives have no effect on him, as they will be redirected, even if he is unaware of their presence. He must consciously allow things like gravity and light to affect him. It is because of his ability that he has an albino appearance, as his "reflection" blocks all unnecessary ultraviolet radiation, thereby preventing the skin from manufacturing melanin. However, if one can find their way "around" his redirection ability(as demonstrated by Touma and Kihara Amata), it is shown to be rather useless, marking Accelerator as a Glass Cannon due to having a strong ability but a somewhat weak body(as Touma/Kihara managed to bring him down to his feet in only around 10-7 blows). Thus far, he has shown the following ways to use his powers:
 * 1) Earth Stomp: Using the vectors behind his feet, he causes a little explosion made of earth and rocks to attack his opponents. In the beginning of the series this was his most common way to attack. He can Snapshot20101120224235.jpg use this to propel himself forward, as seen in the Sisters Arc, or during his schuffle with Awaki, seemingly extend the applied force to other surfaces as well from the initial stomp, such as shattering multiple windows of a building nearly. (Though Accelerator was offscreen, thus it is not yet proven if it can work that way.) If that's the case, the maximum range that Accelerator can extend it to is unknown.
 * 2) Vector Shooting: By touching an object, he can use his ability to change the magnitude of vectors he comes in contact with, such as seen during his fight with Kamijou Touma in the Sisters Arc. This allows him to change the vectors of objects in such a way that he can turn them to projectiles. An example of the use of this ability is in his fight with Touma, when he lightly kicked a rock to make it shoot like a bullet, or when he stomped on train rails to push them out of their sockets, and lightly knocked on them to make those rails rain upon Touma. This ability also allows him to mimick superhuman strength, as he once used it to pick up and throw a building.
 * 3) Wind Control: He can re-vector the surrounding winds and force them to congregate at a single point creating an extremely high velocity wind, but it had flaws like when the wind is moving in an abnormal direction or when his vector calculations are disturbed by sound as showed as with Kihara in the Volume 13.
 * 4) Plasma Storm: He can even create plasma by further compressing the wind at high speeds in a single point.
 * 5) Kinetic Blast: Shown in Volume 13, he takes control of the planet's rotational vectors and transfers an enormous amount of that energy into one attack. This attack used up so much of the planets rotational energy that it slowed down the the earth's rotation by about 5 minutes.
 * 6) Brain Hacking: In accord to him by redirecting the electrical signals of the human body he can take 'control' over them and rewrite the memories and personality of the people as showed with Last Order in the Vol.5.
 * 7) Flight: By controlling the wind around him he creates about 4 high-powered tornadoes behind him to allow him to fly. Showed in Vol.8 and 15. He is also able to redirect the vectors of gravity upon him.
 * 8) Reverse Engineering: Shown in Volume 22, chapter 11; The Accelerator has stated that as long as he has experienced it, he can analyze forces unknown to him as long as his body has been in contact with it, by following the vectors that have been applied(almost similar to a vaccine shot's case). He used this ability to understand Aiwass' "inexplicable laws".
 * 9) Bullet Redirection: Shown in Volume 15 in his fight against Saraku. When his gun sight is thrown off in this fight, Accelerator simply pointed the gun at himself then fired, redirecting the bullet to hit his enemy, stating that his ability was far more precise than any gun sight.
 * Awakening: He awakens towards the end of volume 13 when he had a epiphany right before he was nearly killed by Kihara, and fully awakened in his fight with the other "Awakened" level 5, Kakine Teitoku in Volume 15, during which he displayed a massive difference in power between them. When he Awakens, Accelerator usually loses almost all conscious control of himself and begins to speak in the language of the Angels. He gains the ability to control and create "imaginary vectors", and no longer needs to be touching vectors to control them. When Awakened, he manifests massive black wings, stated to be made of the same "Dark Matter" that the #2 Level 5 Kakine Teitoku creates with his ability. These wings do all the vector-related calculations for him, implied to be a much faster rate than his original calculating abilities- perhaps infinitely so, and as a result he does not need the Misaka Network to manipulate vectors and "imaginary vectors" in his awakened form. In volume 22, due to his pillar of support being changed by an epiphany after being defeated by Touma again, he manifests white wings and a halo and is able to block a massive amount of Telesma that Fiamma of the Right launched from the Star of Bethlehem. The Angelic nature of his ability is described as "The One Who Wields the Power of God" (「神にも等しい力の片鱗を振るう者」).
 * Machine Ingenuity: Accelerator is also quite competent with machinery and technology, evident in when he modified his cane with various gravity sensors, and small motors to help better support himself.
 * Magic: Accelerator has demonstrated the ability to use magic. In volume 22, he used his vector ability to interpret the song used by Index to save Last Order and repeated the breathing method, casting the spell. As this was a pure magic spell, he suffered serious harm but saved Last Order. This is a possible factor that lead to Accelerator gaining White Wings, replacing his Black ones . After an explanation on the theory of magic provided by Leivinia Birdway, Accelerator displays his extreme delicate control over magic to having a side effect of using magic as unnaturally sweating rather than rupture of blood vessels and organ damage.
 * Magical Knowledge: By having a rough idea what Feng Shui was he is able to use a limited magic detection and then combining his knowledge of group psychology it becomes accurate.
 * Firearms: After his fight with Kihara Amata, Accelerator realizes that he can no longer depend on his ability all the time. As such, he gets training with firearms and is shown to be extremely proficient in their use. Using his left, weaker hand he was able to finish off a round of practice in 70 seconds. He has commented that reloading a pistol in two seconds with just one hand and his teeth is too slow, even though he was just testing the guns.

Toaru Majutsu no Index-tan
Accelerator reenacts his battle with Touma in the second episode of Toaru Majutsu no Index-tan, during the scene where Touma slaps Accelerator's hand away, instead of attacking like in the regular anime, he blushes. He reappears in the final scene of the special, reenacting the scene where he creates plasma. During that scene, he exaggerates his laugh and comments on how he is no longer has a weak voice and an amateur as he won an award for his voice work (referring to his seiyuu), he later apparently kills Touma after an explosion which uses the dust explosion scene from the regular anime.

Dengeki Gakuen RPG: Cross of Venus

He is however, still powerful, able to use Redirection at certain times and uses Plasma Storm as his primary attack, he can also move very fast to close in on a character player. He also has A one-hit knockout move, where he touches the players and using his vector abilities to knock them out.

Lunatia
{C}{C}The Accelerator is one the NPC characters that will assist the player in the japanese version of the Korean MMORPG Lunatia.

Toaru Majutsu no Index (PSP game)

 * Main article:Toaru Majutsu no Index (PSP game)

Accelerator appears as a playable character in the game. One notable aspect of his appearance is that he has already incurred brain damage and has to use the Misaka Network to do his calculations, though he retains his black shirt with white stripes and lacks his cane. (as he tosses it away in his battle intro, making it seem that his powers are a bit more intact similar to pre-Toaru Index II.)

Trivia

 * Although Tree Diagram predicted that in a fight between him and Misaka Mikoto, she would die in the 125th move, the version of the SISTERS Arc in the Railgun manga shows that she would have been killed just by reflecting her strongest move, the Railgun, in the 4th move. Of course, this prediction is probably based on Accelerator's tendency to play with his opponents.
 * The artist in charge of the illustration of the light novels, Kiyotaka Haimura, made a genderswap version of Accelerator wearing a sailor school uniform in the extra pages of the Volume 8, based on Accelerator's thin figure which makes him look like a girl due to his esper ability that upsets the balance of hormones in his body. Due to Touma once speculated Accelerator's real name to be Suzushina Yuriko (鈴科 百合子) the fandom who have read the novels in Chinese and Japanese have been joking whether this is really his real name and Accelerator is actually a girl. In addition, the jokes include if Accelerator turns out as a girl would (s)he end up falling for Touma as well.
 * When spoilers on Volume 20 was first released, there was the misconception that Accelerator had somehow managed split the country Russia into two halves. Later this is found to be false, stemming from a mistranslation in the narration at the part where Accelerator has just defeated Misaka Worst.
 * He is shown to have a liking of coffee as there is references in the light novel of him buying / wanting to buy coffee. He enjoys the same brand of coffee that Touma likes(black coffee without sugar), and at least in one opportunity (Volume 5 light novel, before encountering Last Order and after his defeat from Touma) he actually bought every coffee can left in the store, "foiling" Touma's attempt to buy coffee the next day. (Another possible joking nod to Touma's "misfortune.") It could be seen as a slight irony via Accelerator's character development.
 * Due to his unusual introduction to Last Order and his equally unusual reaction to seeing her naked, not to mention their close relationship and the way he attracted Index's attention in Volume 12-13, fans have been joking that Accelerator might secretly be a lolicon. Misaka Worst lampshades this in New Testament Volume 1, because Accelerator is looking to help Fremea Seivelun.
 * Although Accelerator has an automatic deflection to every vector that comes into contact with him, it is not explained how his (noticeably) well-fitting clothes stay on him, although they may be included in the small exceptions his redirection makes for necessities, such as oxygen and food.
 * It is not explained how limited Accelerator's auto-reflection is, since all attacks that make contact with even his clothes are deflected. Although Accelerator has shown his ability to use vectors to accelerate his own movements by pushing off the earth with his legs, there remains a fan speculation that brings up a flaw in his powers using net force. If Accelerator automatically deflects all forces, one step could cause massive destruction, as when his foot applies pressure to the ground, the earth in turn "pushes up" on him, attempting to create a net force of zero, thus causing the force to be deflected against the ground again, and so on.

Quotes

 * (To Imouto 10032 in Vol 3)"I strive for something beyond the strongest, that challenging me would be the most ridiculous thought ever, that fighting me would be a sin!"
 * (To Last Order in Vol 5)"People have done this much to you. Sorry for taking so long...to save you".
 * (To himself in Vol 5)"I'm too naive. With thoughts like 'If I saved someone maybe I can start all over again'".
 * (To Amai Ao in Vol 5)"No matter how much of a scum bag we are. No matter now many excuses we put forward, those can't be the reason to kill this brat!"
 * (To Musujime Awaki in Vol 8)"In this pathetic state, I know it's impossible for me to ever become Academy City's 'Strongest' again... But I've already made up my mind... In the eyes of that brat I will always be the 'Strongest', scumbag!"
 * (To the maintenance crew member in Vol 14) "They may all look the same to you, but there are different knids and different levels of evil. A first-class villain doesn't target honest lives."
 * (In Vol 14, refering to Academy City's troops) "Someone needs to tell those assholes there's such a thing as too much force. Using a blade for severing continents on a flesh-and-blood human is just wrong. I mean, how am I supposed to confirm the remains? Well, since the riots stopped after the blast, I guess the objective was carried out."
 * (To Tsuchimikado Motoharu in Vol 15, refering to Last Order) "What's with that brat showing up in a situation like this!? That 'God' bastard sure is messing around!"
 * (To Kakine Teitoku in Vol. 15) "Fine, now is a good time to teach you something: even Villains have standards!"
 * (When asked who he is in Vol.19) “A Villain that’s no better than a piece of shit.”
 * (To child in Vol.19) "I’m the Strongest Level 5, I don’t need brats worrying about me. Listen, even if someone is suffering before you, the kind of person that can take up arms without hesitation to shoot down the villain is no better than a villain himself. The kind that doesn’t care about others, doesn’t give 2nd chances; someone that kills is given a reason, is definitely not a hero. You don’t have to become that kind of person. That’s my specialty. Only I have to go through that"
 * (Vol. 20) "“You god damn fucking pieces of shit!! You rotten fuckers look down on me thinking my powers can only be used to kill!! I’ll show you right now!! Just like when I saved that brat from Amai’s virus back then, I’ll show you that I have the power to proteeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeccccccccccccccccccccccccccccccccctttttttttttttttttttttttttttttt!!”"
 * (To Touma in Vol. 20) “It’s ridiculous that a villain who was no better than a piece of shit like me was guarding her!! No matter how you think about it something must have been wrong!! How could I possibly be a hero!! No matter what, I can only choose the blood-stained path!! Why do I have to do all these things!! If a hero like you had shown up earlier, then something like this mix-up of position wouldn’t have happened!! That brat would not had to have suffered as much this way!!!!!!!!!!!!!!!!”
 * (Vol. 21, talking about Last Order)"AAH!~ Fuck, I admit it! I want to protect her! I dont want to lose her!! I don't even want to think about the possibility of losing her!! I will face anything in order to protect this dream of mine!!!!"
 * (To Last Order in Vol. 22) "I wanted to be with you forever, too."
 * (Vol. 22) "I get it... this is what it means to fight to protect."

 * ( NT :Vol. 1) It’s true I have no real reason to protect her, but that’s no reason to just let her die
