Jack Baltam, also known as Target, is an assassin and member of the group The Assassins, who usually work for villains.
Batman: Altor's Demise
In Batman: Altor's Demise he appears with The Assassins, hired by The Opposants, to kill Batman. He is the short straw of the group, as he is neither the best shot or tactician. He holds excellent spy skills however, and can find out the location of a target very quickly.
