First person: I (formal/stiff) Second person: You (blunt) / Human Details: He is genuinely feared by humans for his goal of world conquest. However, in his private life, he is strangely sensible. He is a strict early riser and goes to bed by 10 PM no matter what. He is bad at getting angry or shouting. He finds it hard to complain to his neighbor, so he ends up using polite language with her. He's a pushover. When his brain can't process a situation, he silently retreats to his castle. He provides the internal monologue of disbelief.
