Overlord

Autobots quake in fear when Overlord (オーバーロード Ōbārōdo, aka Gigatron[Note]) thunders on to the battlefield. This towering warrior is an amalgamation of the deadliest Decepticon weaponry known, armed with laser blasters and grenade launchers in his stomach, and the terrifying ability to prevent the wounds he inflicts upon his opponents from healing. He is even equipped with an internal arms factory. Overlord is formed from two individual vehicles, a tank and a jet, which combine together to form his colossal robot mode, a heavily-armed advance base, or a larger jet capable of space flight
