Megatron

Beast Mode: Tyrannosaurus Rex/Dragon-----Special:NONE

Megatron, like his namesake, is totally evil. He drags the Maximals into the Beast Wars. He mangages to find the Golden Disks in the second season and nearly destroys the pre-humans, until Dinobot sacrifices himself to save them. He later finds The Ark, with the Autobots inside, and literally blows off Optimus Prime's head. Due to this event, Optimus Primal is changed to Optimal Optimus while holding Prime's spark. When Megatron attempts to duplicate this with the original Megatron's spark, he is changed into a dragon. After he finds the Nemisis, he is betrayed by the ressurected Dinobot and looses to the Maximals. In Beast Machines, Megatron takes over Cybertron and creates a Vehicon army. Even with five different generals on his side, he is on the loosing side. When he purges himself of his beast mode, he becomes a flying head. When this is caputured by the Maximals, his loose spark inhabits a diagnostics drone, he creates a Optimal Optimus copy and is finally killed by Optimus in a kamikaze attempt, and with their deaths balance is brought to Cybertron.
