Megatron Megatron is the leader of the Decepticons. When the Minicons' awakening was detected, he took his elite squad to Earth to locate and capture the Minicons so he could use their power to defeat Optimus and take over the universe. He scanned a military tank as his alternate mode and had Leader-1 as his Minicon "slave". After many battles, he gained the StarSaber, SkyBoom Shield, and Requiem Blaster. With them serving as batteries to power the HydraCannon, he returned to Cybertron to be victorious. On the way to Cybertron, Megatron received a power-up when Leader-1 sacrificed his lifeforce to protect his master. In either normal or his Super-Form, self-dubbed "Galvatron", Megatron can use Tidalwave as armor. Despite getting the upperhand against the Autobots, Megatron reluctantly sides with them when Unicron revealed himself. But once Unicron is no longer a threat, Megatron resume his vendetta against Optimus in a 1-on-1 duel. But after he lost, Megatron vanished into the depths of Unicron as the giant used his remaining energy to escape.
