Brain (Fairy Tail)

Brain is a villain from the manga/anime, Fairy Tail. He was the leader of the Oración Seis, a Dark Guild composed of highly powerful Mages whose goal was to find a very destructive Magic known as Nirvana, which was sealed away long ago. Inside him dwelled another, more evil and dangerous personality known as Zero before his death at the hands of Cobra.

Appearance
Brain has neat silver hair that reaches his shoulders, dark eyes and dark skin. He has unique markings on his face that take the shape of straight black lines, ones that begin to disappear when the members of the Oración Seis become incapacitated or killed. He is slightly taller and more muscular than most people.

After Brain's alter-personality Zero is unleashed, his appearance changes slightly. His hair becomes wavier, his eyes have turned blood red, his skin becomes a much paler color, and his outfit becomes something reminiscent of a military officer's outfit.

Brain's Oración Seis mark is located on his chest, however, when Zero takes control of their body, his Guild Mark seemingly disappears.

In X791, Brain's appearence is relatively the same as seven years ago, except that he has grown some facial hair on his chin.

Personality
Brain does not respect his opponents, as he often calls them trash or maggots. He is willing to do all that is needed to achieve his goal, which is to awaken Nirvana, a very destructive Magic. As the leader of a Dark Guild, he is cruel, even to his comrades, as he attacks Cobra for losing to a so-called regular guild. His comrades are just puppets to him, as he says that he can just find new ones when Nirvana is activated.

Brain has two personalities: the face he shows to the world, which loves fame and goes by the codename "Brain", and another hidden face, which loves destruction and goes by the codename "Zero". Comparatively, Zero is much more merciless than Brain, and only seeks to destroy anything and everything he can. Zero states that from his perspective, if someone or something has still some kind of form, he, she, or it is worth destroying. This methodology led to him attacking Klodoa, the seventh member of the Óracion Seis. Brain seems to be somewhat afraid of his other self; as a consequence, he used every Oración Seis member as a "key" to lock his other personality away.

History
Brain was once in charge of the Bureau of Magical Development, where he created hundreds of types of Magic, one of which being Self-Destruction Magic, which he eventually taught to Jellal. During his time working there, he took Ultear Milkovich from Ur in order to heighten her already abnormally high Magic Power to make his own ends meet. However, Ultear's power was too great, leading Brain to realize that he wouldn't be able to connect her to his Six Prayers. Brain then left the laboratory moments before it was destroyed.

Brain later traveled to the Tower of Heaven and took five children with the greatest Magic Power and trained them. Those five children eventually became members of the Oración Seis and part of the Six Prayers that sealed Zero away.
