Galvatron

Galvatron is a Decepticon and a main character in the scrumblebee comic. He is the main villain of The Galvatron Crisis Arc. He is an experiment gone horribly right, for the Decepticons at least. He is the reborn form of Megatron, created with reformatting technology infused with Dark Energon.

 The Galvatron Crisis Arc 

Megatron was reborn as Galvatron thanks to the efforts of Soundwave, Ravage, Laserbeak, Rumble, Starscream, and Scourge. After he was revived, he was told what had happened in the battle, including the death of Shockwave and the retreat of the other Decepticons. Galvatron and the others then went to the scorched wasteland planet of Chaar. Galvatron hired the mercenaries Lockdown, Dropkick, and Detour. Optimus Prime arrived, and, after damaging his power armor, decided to test his mercenaries by making them fight Optimus. However, Ultra Magnus arrived, and the mercs were defeated. After Detour and Dropkick recovered, Galvatron sent the three to Planet X. Galvatron then went there himself. He told Sixshot who he really was, and Sixshot and his many troops joined him. After Hellbat told him that the Autobots were on Chaar, he sent Sixshot to destroy their communications. Later, he intercepted Jazz and Ultra Magnus's ship. After he ordered Starscream to crash the ship, the ship split in two upon re-entry, with the Autobots and Decepticons at different crash sites. After sending Darkwind back to base and calling in Dezarus and his troops, he attacked the Autobot crash site. While Computron and Liokaiser were fighting, he fought Optimus. Galvatron then cued Starscream to stab Optimus in the back with the Extractor, and take his spark. At the Decepticon base, he told Optimus of his plans for a Decepticon victory. Later, his ultimate project, the Nemesis, was completed. During the Final Battle, he and Soundwave fought Ultra Magnus and Jazz. He used his cannon to blow off Ultra Magnus's arm. While Jazz distracted him, Ultra Magnus knocked out his thrusters, preventing him from flying away. Rather than retreating, Soundwave stayed by Galvatron, and extracted his spark. The two escaped in an escape pod before the Nemesis crashed.
