Like most DJs in Vice City, Adam believes that his kind of music is the best, and fancies himself a music connoisseur. In Grand Theft Auto: Vice City, he mentions his liking for money, is a big fan of hang gliding, despises music videos because they show that the artists' looks are more important than actual talent, and insists that his mother had "nothing to do" with his "personal choice" of going into radio.
Similar to the situation with the earlier version of V-Rock, Flash FM and Emotion 98.3 circa 1984 in Grand Theft Auto: Vice City Stories, Wave 103 in 1984 features two hosts, the British Trish Camden and American Adam, who have conflicting personalities which lead to much argument on the radio. Adam believes that radio is better than music videos, whereas Trish's point of view is the opposite. Trish also mentions that Adam likes to wank (jerk) off to New Order's Blue Monday.
Adam makes a cameo appearance in Grand Theft Auto: San Andreas as a caller to the conspiracy theory show Area 53 on WCTR in 1992. He says that while hang-gliding in Bone County, he saw a man at a trailer compound performing strange rituals with a Domestobot. The show host Marvin Trill (who is later revealed to be the man that Adam saw) tells him to get a real hobby, and hangs up.
He is voiced by Jamie Canfield in all three appearances.
- In Grand Theft Auto V, he's one of the honored celebrities on the Vinewood Walk of Fame.
- Adam is one of the many characters to make an appearance in three games in the 3D Universe. The others are 8-Ball, Maria Latore, Salvatore Leone, Toni, Michael Hunt and Donald Love.
