John can twist his body around like a pretzel. He's basically a rubber band man since he studied the stick figure body. He's very adapatable.
Quincy has an annoying laughter that can make your ears bleed. He's also very acrobatic and uses a pogo stick to fight.
He also knows martial arts.
With that said, I'm not the powerscaling type? When I write stories where characters have powers and all that, I have them all on an equal level where they could be picked off at any moment. Even if one can destroy the universe he can still lose to a tiny mouse with no powers or sentience :v
I also love it when a powerful character can be picked off in an anti-climatic fashion.
