Mukade

Mukade was a Jonin from Sunagakure and later left Suna and became a servent of the Akatsuki. He was used, along with fellow missing-nin Yura, as sacrifice and transformed into Kisame Hoshigaki as a pawn and was sent to stall Team Guy while the Akatsuki extract the One-Tailed Shukaku from Gaara. Might Guy opened the 6th inner gate and killed the Kisame clone, only to find that he had actually killed Mukade in the process.
