Gigatron

ギガトロン / デビルギガトロン

Gigatron (Megatron in the English dub) is the leader of the Destrongers (Predacons in the English dub) and possesses the ability to assume six forms. He claims to have decimated numerous planets during his campaign for Destronger supremacy before arriving on Earth in search of the megaweapon Brave Maximus (Fortress Maximus in the English dub). He appears to have clashed with Fire Convoy (Optimus Prime in the English dub) and his Cybertrons (Autobots in the English dub) on numerous occasions previously.
Although Gigatron is a great and powerful warrior, he typically leaves the fighting to his Destronger lackeys, such as Gelshark (Sky-Byte in the English dub), preferring to stalk around his nameless mobile base headquarters (known as "the Megastar" in the English dub) and berate his underlings when they inevitably fail. Upon his conversion to Devil Gigatron (Galvatron in the English dub), he becomes significantly more active and effective. His primary attack seems to be his Cutter Beam technique. As Devil Gigatron, he can increase his power by draining the life energy of other beings!
