Gigatron

Autobots quake in fear when Gigatron thunders on to the battlefield. This towering warrior is an amalgamation of the deadliest Sith weaponry known, armed with laser blasters and grenade launchers in his stomach, and the terrifying ability to prevent the wounds he subjects upon his opponents from healing. He was Darth Grievous's worst Demon General in the Sith Army and can teleport by using his cape and turn enemies into stone.

He got into a fight with Jetfire on Hoth after he Petrified the other Autobots to prevent them from assisting Jetfire. During the battle Jetfire shoots Gigatron with his blaster but Gigatron used his cape to protect himself from laser fire. The two Transformers continued battling each other with lightsabers, throwing things at each other and even punching and kicking each other. Jetfire was close to finishing off Gigatron until he teleported away to Korriban by wrapping himself with his cape.

The two meet again on Korriban only this time Jetfire prevails against his arch enemy by cutting off Gigatrons hand and severing his head and crushing his severed head.
