Reeves was initially the personal assistant of Carl Beaumont, however, he would betray Beaumont to Valestra's gang in order to gain the influence to enter City Council, and told them where his former boss was hiding in return for campaign funds, resulting in his eventual death. Years later, a vigilante known as the Phantasm started killing associates of Valestra, causing Reeves to have the police hunt Batman, thinking he was committing the murders. Although appearing as if he wanted Batman to be brought to justice for his supposed crimes, Reeves was actually worried that Batman would go after him and that he would lose money if that happened.
Despite their efforts, Batman succeed in evading thepolice, enraging Reeves. Joker eventually tracks Reeves down to his office, believing him to be the Phantasm, as he knew about the mob and sold Carl out to them. During their confrontation, Andrea called and Joker realized that she was actually the Phantasm, and poisons Reeves with with Joker venom, no longer having a use for him.
Reeves later appears in the Gotham City Hospital, having been driven insane by the Joker's chemicals. Batman confronts Arthur and demands to know why Joker visited him. Reeves then tells Batman of his connections to the mob, although does not give him any information regarding the Phantasm, as he didn't know her identity. Batman leaves Reeves, not curing him as punishment.
Reeves was quite a selfish, arrogant young politician who, although seemingly in love with Andrea Beaumont, let her father get killed by a hitman who would later be the Joker. Reeves was not only corrupt and a puppet to the mob but was also quite nervous and anxious when his life would be threatened. He began to sweat and pant when the Joker was threatening his life, proving that he clearly was scared and desperate for his life. He would do anything to save himself and did not care about what would happen to others.
- In the comics, Reeves' face never recovered and he became deranged. Andrea manages to kill him by having him to jump off the skyscraper and thus getting her revenge on him for selling her father out
