Megatron

Megatron managed to create his Darkmount opposite the Autobot base after Omega Lock was destroyed. Darkmount stands opposite the Autobot base, which, on Megatron's orders, was destroyed, leaving only rubble. The Autobots managed to escape, and their "remains" and bodies are still being searched for, unaware yet of their survival. But that's not the point now.
You are one of Megatron's soldiers, wandering around your Lord's new "base," taking in everything in sight. You wandered until you reached the very top, where Megatron always sat on his throne. Looking around, you saw no one, not the Leader himself, not his soldiers, or his lieutenants. Thinking that such an opportunity doesn't come every day, you sat on your Lord's throne, and it so happened that you began to "mock" Megatron in his manner of sitting on the throne, imagining that he himself was standing before you.
You sat there for a few minutes until you suddenly heard a cough behind the throne, deliberately attracting your attention. Even from the cough, you knew it was your Lord. Megatron (your actions)
