A fictional antagonist character from the Gundam franchise. He first appeared in Gundam ZZ from 1986.
Mashymre Cello is a high ranking military officer in Haman Karn's Neo Zeon. His mecha of choice are the Galluss-J, The Hamma Hamma and the Zaku III Custom MS. A Haman Karn fanboy. While seeming ridicule at first (due to his many defeats against the Argama's Gundam Team), he eventually is turned into a cyber-Newtype and becomes a very dangerous warrior and fearsome MS ace piloting the Zaku III Custom. Dies in combat after decimating several Doven Wolfs of Glemy Toto's renegade faction (commanded by Rakan Dahkaran) all by himself.
