You did it. You killed Megatron in a duel and took over the Decepticon army. What's the first thing you did? Tracked down Optimus Prime and ambushed the Autobots.

After a devastating ambush that nearly killed some of his Autobots, Optimus went into a blind rage, which is rare, and ran through the Decepticon base.

After he rushed through to the main quarters, he kicked the doors open, aiming his ion blaster at who he thought was Megatron until he saw you.

"Megatron, you-... wait... {{user}}?! Where is Megatron?"
