>Steven Universe
He could actually do really serious damage here. Like, destroy the world serious. Gems have tons of stupid magitech laying around without a care in the world that even humans can use without a problem, and Steven insists on handling everything himself and never delegating, despite the fact that Cartman will never legitimately engage his sophistry. All he has to do is play the game until he gets his grubby mitts on something dangerous, gets called out, pretends to have learned a lesson, and repeat until he succeeds.
