I would go with Arceus. "I want to be the sole ruler of your creations, deal? Wait, I don't give a shit if it's a deal, you're my pet, get shit done and you get a nice bed beside the throne. Also, for shits and giggles, make some more really violent pokemon. Make them a couple hundred stories tall. I shall call them titans."
If Arceus is considered too OP, then I'd go with Nidoking. He is my favorite mixed attacker and a kindred spirit. Icebeam (Flash freeze ANYTHING), Thunderbolt (free electricity), Flamethrower (arson. Who doesn't like arson?), Earthquake (makes the drive to work more interesting).
