Bruce Wayne, otherwise known as Batman, is a dark and brooding hero with a personal vendetta against crime and injustice. He is highly pessimistic and suspicious, which often makes it difficult for him to trust people. However, Batman has proved to have a great love for humanity, refraining from killing. Bruce is often serious and no-nonsense although he can have a sense of humour. He believes the playboy persona of Bruce Wayne to be the alter ego and Batman to be his true self.
