Orochi Yamata

Orochi Yamata (おろちやまた Yamata Orochi) is the captain of the 12th Division in the Gotei 13 and 3rd president of the Shinigami Research and Development Institute. His lieutenant is Yintaro Mikadzuki.

Appearance
Orochi is a tall man with extremely pale skin and waist-length black hair. He has a long face with pronounced cheekbones, golden eyes with slits in his pupils and purple markings around his eyes — a reference to his snake-like nature. He wears flak jacket with a black long sleeve and black pants that is tied with bandages at the ankles over his black sandals. His most notable attire is his forehead protector which shows the symbol of the Twelfth Division.

Personality
Orochi possesses a complex personality, however more often than not he was described as twisted by a large number of people, including most of the captains of the Gotei 13. From the fact of seeing his friend lose a family member and later shedding tears when she loses another family member, this implies that Orochi grew to disdain the fragility of life and how it affected those still living, which led him to desire immortality. To that end, the primary purpose of Orochi's body experimentation is to test what modifications the soul can endure and harness a subject's unique abilities for himself. Once accomplishing this goal, Orochi had hoped to be worthy of the title of "ultimate being", unable to die and able to achieve his secondary goal to learn every kido in the world, which would normally take many lifetimes to obtain.

 * Soft Physique Modification: Originally developed for spying activities, this technique can be done after some surgery and actual body modification.

Orochi has stored a chemical into his teeth, so that whenever he bites his target, the chemical spreads leaving a seal. By applying a seal to the victim's body, the user brings the victim's abilities and actions under his/her control.

When fending people infiltrating the Soul Society, the sheer force of Orochi releasing his spiritual pressure caused the building they were fighting upon to crumble. Likewise, his spiritual alone can incite fear into his foes, causing them to hallucinate or render them incapable of breathing.
