Mushizo has a very strange ability to control wasps. Not only can he talk with and command them, in Jubei's fight with him we see that Mushizo is a walking hive.
Mushizo's weapon of choice is a 2 pronged pitch fork type weapon, and has a deadly "throat needle" which he can spit out of his mouth. The only thing is he really shouldn't go near water. Although not the most amazing Devil, he is the Devil who reveals to Jubei the existance of the once very dead Gemma. And if that weren't bad enough, he is the leader of the Devils of Kimon.
