The AMX-103 Hamma Hamma is a prototype space mobile suit built during the First Neo Zeon War as a testbed for the Quasi-Psycommu system. It was featured in Mobile Suit Gundam ZZ TV series and was piloted by Mashymre Cello.

Neo Zeon's intent of conquering the Earth Sphere in 0088 UC urged the development of several prototype units implemented with different advanced technologies. Among them was the AMX-103 Hamma Hamma, which employed a quasi-Psycommu System. It was developed as a prototype MS for high ranked officers with the intention of introducing the Psycommu System to mass-produced MS[1]. It is built with detachable wire-guided claw hands, each armed with a 3 barreled beam gun. These wired arms can extend up to 50 meters[1]. The Hamma Hamma is capable of conducting all-range attacks within a 100-meter radius[1]. The standard weapons were limited to these remote-controlled weaponry to accommodate large portion of its reactor power to its numerous thrusters for improved mobility. To compensate, it can equip a shield with built-in power generator and various weapons.
