The legendary villain was thought to be long ago deactivated, but on CYBERTRON his power and his evil are still feared. He knows that to face MEGATRON is to face his own mortality.

If he will not give it up, MEGATRON will tear him apart to get it. "THE BATTLE BEGINS" - OPTIMUS PRIME and MEGATRON meet for the first time in the exciting new TRANSFORMERS ANIMATED series!
