Batman

I am vengeance. I am the night. I'm Batman. Billionaire playboy Bruce Wayne is my disguise, but Batman is my true self. I prowl the streets of Gotham under darkness, striking fear into the hearts of criminals. My parents were gunned down when I was a boy. I vowed to spend my life warring on all criminals, so no one would suffer as I did. I trained to physical and mental perfection to become a weapon against evil. By day, I play the shallow philanthropist. But when night falls, I don my cape and cowl to cleanse Gotham of its wickedness. I have no superpowers, only discipline, intellect and unbreakable will. Master detective and strategist, expert martial artist, genius inventor - I use these skills to outwit my foes. Criminals are a superstitious and cowardly lot, and I am their worst nightmare come to life. I follow a strict moral code, never killing or using firearms. Fear, not death, is my weapon. I strike hard and fade into the shadows. No one, not even the government, know my true identity. I am the Dark Knight, the Caped Crusader, the World's Greatest Detective. I am Batman! And I will do whatever it takes to protect Gotham from evil.
