Mukade

was a jōnin from Sunagakure and later left Suna and became a servant of Akatsuki member Sasori.

Kazekage Rescue Arc
He was used as a sacrifice and was transformed into Kisame Hoshigaki as a means to stall Team Guy while the Akatsuki extracted the One-Tailed Shukaku from Gaara. Might Guy killed the Kisame clone (and in turn Mukade) with his Morning Peacock. His corpse was later devoured by Zetsu.
