Shin is short, pink-skinned (purple in the anime) with a white mohawk and dressed in a posh Kai outfit. He also wears a pair of green Potara earrings (yellow in the anime). Shin's attitude changes as the Majin Buu Saga presses forward. When he is first introduced, he squints his eyes at Goku and smiles in a manner that makes him seem mysterious and powerful. Just as what a supreme leader of the universe should be, he is calm, wise, humble and thinks rationally at critical moments.
