I recently got to see Guardians of the Galaxy and quickly found that Groot, a humanoid tree thingy was ridiculously overpowered. He possessed inhuman strength, could regenerate and grow his limbs at will, had infinite stamina, and could even illuminate areas with these firefly thingies. Being the coolest character from the film, I naturally (get it?) tried to make an origami version. The only shortcoming, I would say, would be the arms which are too short. Oh well, he can grow them out.
