Hexapodus

is a Hollow purified by Ichigo during the Agent of the Shinigami arc.

Appearance
Hexapodus has the appearance of a large six legged spider or beetle. He has gray green skin with orange joints as well as orange spots on his back. He has a plain white mask with a relatively human like face. His face is framed by two tufts of brown hair and forelock of purple hair that falls over the top of his mask, making him look clown-like.

Trivia

 * Hexapodus' name was only revealed later on, when Rukia attempted to collect the bounty for his purification.
