Sasori Izuna

Sasori Izuna (イヅナサソリ, Izuna Sasori) is a former captain of the Gotei 13; he later fakes his death and leaves for the Dangai (断界, Parsing World) so as to increase his already immense power in order to achieve his villainous goals.

Appearance
Prior to his departure from Soul Society, he appeared as a mild-featured man with brown scholarly hair. He wore the standard Shinigami uniform with a captain's haori.

After entering Soul Society for the first time in two hundred years, his overall appearance has changed significantly as his hair has grown longer and he has become more muscular.

Personality
Despite his current villainous status and former position of authority, Sasori is a surprisingly polite, soft-spoken intellectual, often addressing his subordinates by their given names. He rarely shows any sign of alarm or distress and often has entire situations planned out well in advance. Whenever confronted, Sasori is casual and uncaring, attempting to draw out a conversation and chat with his opponents, which often infuriates the one he is talking to.

Sasori initially appeared to be a very kind, well-respected captain and was looked up to by many. However, this was just a mask to disguise his manipulative and very dangerous nature. Sasori claims to be unaffected by any form of morals or ethics as he views them as mere restrictions on his potential. He is, therefore, willing to stop at nothing to further his selfish ambitions. He is fond of long, complicated, and somewhat convoluted plots. Despite all these, he appears to have a bit of pride or honor as he claimed that he would never use psychological warfare in order to win because this is a sign of weakness, although he has been shown to be able to read someone's heart and therefore their emotions. He can use that to see through most of his opponent's moves.
