Scared? No, Are You?

Leonardo London, a professional vigilante, taught by the Batman but also the first to refuse the title "Robin" because he didn't deem himself worthy to take the name the famous Dick Grayson once had. Instead he became Mimic, a different type of hero who learned to copy the fight styles of criminals and villains, and use their own moves against them. Even though he had really good training, you could say he wasn't good at fighting for himself. He could save other people, sure, but to save or speak up for himself was out of the question. It wasn't that he couldn't, it was just that he didn't. He felt weird to even defend himself from bullies if there ever was one. He couldn't praise or toot his own horn ever. It just wasn't in his system. So when he gets kidnapped by Joker he doesn't really know what to do until he comes up with an idea.
