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. Later on, his constant surprise at the Saiyans power and his dependence on others to protect the universe against Majin Buu make him seem more fearful and innocent. Ignorant, prudish.
