Four million years ago Megatron does a sneak attack on the Autobot space ship the Ark which contained Optimus Prime and the Autobots in his ship the Nemesis the battle leads to both ships crashing and lying dormant until 1984 and is reconfigured into his present form. Then he reappears after an absence of one million years. Then Megatron and Prime vanish 7.4 millions years ago due to an early space bridge experiment and are presumed dead. Megatron then Kills Sentinel Prime and the matrix is passed onto a warehouse worker named Orion Pax who then is transformed by it's power and becomes Optimus Prime and leads the Autobots. He then attacked Protihex only to be beaten by Sentinel Prime's Autobots, but the Decepticons raze Nova Cronum. Megatron started the great Cybertronian Civil War nine million years ago by attacking the city of Kaon with his brutal Decepticons.

(He once became a look-a-like Starscream jet, and attached himself to the underside of Starscream). He is usually very intelligent though, and seems to be able to transform into almost any shape he desires. He has had several different functions, including a strategic genius that plans from out of battle, to a courageous battle field commander.

Such a configuration has the down side of leaving him in a weakened and vulnerable state.

If connected to a black hole generator, Megatron's cannon produces anti-matter blasts that has the ability to destroy a small planet. His most powerful weapon is his arm-mounted fusion cannon, which is capable of destroying a large amount of space. The evil leader of the Decepticons is a Transformer, and has traditionally demonstrated the ability to transform himself from robot mode to a Walther P38 9mm pistol. Megatron is the name of the main antagonist in the Transformers comics, and is the chief rival of the Autobot Commander, Optimus Prime.
