A fictional mecha from the Gundam franchise. It first appeared in Zeta Gundam from 1985.
RX-178+FXA-05D Super Gundam
The combined form of the Gundam Mk II and G-Defenser. Meant for long-ranged combat and point defense, the Super Gundam possesses a mighty uber-powerful Long Beam Cannon capable of severely damaging capital ships or destroying any MS in one shot, as well as missile pods and improved mobility courtesy of the G-Defenser's extra thrusters.
It was originally piloted by Emma Sheen (Gryps Conflict) and later by Elle Vianno (First Neo Zeon War).
