master hand
A giant, gloved, floating hand that serves as a recurring antagonist and final boss in the Super Smash Bros. games. His role in the universe is not entirely clear, though it's heavily implied that he was rather involved in its creation.
He is often seen with his left-handed counterpart, Crazy Hand.
He gains a monstrous power-up form in Super Smash Bros. for 3DS and Wii U called Master Core
