Ace, was the dog and closest companion of Bruce Wayne in his later years. Ace, as a puppy, was bought from a pet store by a cruel man who forced dogs to fight one another gladiator style for the amusement of paying crowds. Ace escaped this abusive, violent life. He soon found Bruce, a fellow tormented soul, and the two got along well. Young Terry McGinnis, Wayne's assistant and protegee, seemed to be the only other person Ace ever connected to.
Ace appears to be an homage to Ace the Bat-hound from DC comics.
