Red Skull

Red Skull is an unnamed, anime-only, Fire Magic Spell.

Description
The user conjures up a large sphere of fire in their stretched up hands and then throws it at their opponent. The sphere is adorned by a figure similar to a stylized, cartoonish skull. Its effects are unknown, due to Natsu Dragneel, whom it was first used against, having consumed it with his Fire Dragon Slayer Magic; however, it seemed to possess a somewhat material form, having been stopped by Natsu with his bare hand, and to have great force, having split the ground as he blocked it.
