Dana Tan was Terry McGinnis's girlfriend. She never knew of Terry's life as Batman and was soon sick of Terry blowing her off due to his duties as Batman. When her brother, Doug, was released from prison she broke up with Terry. Doug was soon brought home by the police after questioning, because he was a bystander of a Jokerz robbery, and this led Dana to worry about him deeply.

Since breaking up with Terry she tried numerous times to talk to him about their relationship, but Terry consistently rebuffed her claiming to be too busy.
