Suikotsu

was a member of the Shichinintai.

History
Suikotsu has two, definite split personalities. One, a gentle, philanthropist doctor who looks after orphans; the other is a sadistic killer with a wolverine-like appearance that earns him his spot in the Band of Seven. When his evil side takes hold he seems to possess a dry sense of humor and an insatiable desire for blood, while when his good side is in control he often hallucinates that he has blood on his hands. He may have a third personality, as shown after he falls off a rope-bridge; this personality seems to be a combination of his other two. Doctor Suikotsu develops a close, empathic relationship with Kikyo.

When his evil side is in control, he has six green tiger-like markings on the edge of his face. The markings are strikingly similar to what a general evil character has painted on their face in Japanese opera.

Death
In both the anime and manga, Suikotsu dies after a battle with Kikyo and Sesshomaru, the latter of which decided to fight him after he kidnapped and threatened to kill Rin. After suffering a fatal attack, he asks Kikyo to remove his jewel shard from his neck so that he can die peacefully. Sadly however, Jakotsu removes the shard instead.

Abilities
When he is good, Suikotsu is a skilled healer who can make several remedies with various herbs for various injuries. He is often compared to a saint.

While his evil self is out, he has athletic attributes that rival those of Bankotsu & strength that rivals Inuyasha. He wields a pair of Tiger-Claws. He also claims to be an expert of close-range combat.
