- Luis: "Where's Tony?"
- Evan: "Where's Tony?, Where's Tony? What's wrong with 'Hi Evan, you're looking cut'. 'Hi Evan, like a drink?'. 'Hi Evan, if I wasn't straight I'd ravage you right now'."
- ― Evan Moss and Luis Lopez.
An ex-bodybuilder native to Arizona, Evan is the on-again, off-again boyfriend of nightclub owner Anthony "Gay Tony" Prince, and a major reason to why Tony uses drugs. Because of this, he is highly disliked by TBoGT's protagonist, Luis Fernando Lopez.
Evan was an ex-bodybuilder in his native Arizona. He later moved to Liberty City and became a popular male model. He started dating Gay Tony and got him hooked on drugs. Luis warned Tony that Evan was a bad influence on him, though Evan and Tony continued to stick together even after breaking off and getting back together on several occasions. Because of this, Luis always disliked him, thinking him as a selfish, gold-digging leech that only stuck around for Tony's money and brought drugs into Tony's already complicated life.

Evan is first seen in the mission Bang Bang, dancing and singing to the Hall & Oates song "Maneater" in Tony's apartment. As Luis walks in looking for Tony, he playfully stands in his way until Luis cuts the record off. Evan taunts Luis as he asks for Tony, instigating a brief argumental confrontation. Evan brushes the insults off and informs him of Tony's location; passed out in his bedroom.
As they leave, Evan asks to come along. Luis responds with a headbutt, breaking Evan's nose. Luis tells him to leave before they get back. As Luis heads out the door, Evan calls him a "fucking hetero."
- Luis: "You really think Evan's dead?"
- Tony: "I'm sure of it! He bleeted, didn't he?"
- ―Luis and Tony discussing Evan's fate.
The next time Evan is seen is in the mission Frosting on the Cake, attending a coke party in Tony's apartment along with Rocco Pelosi, Gracie Ancelotti, and Sharon Morton. He decides to go along with Tony and Luis as they're headed out to buy some diamonds from a smuggler aboard the Platypus. Luis drives a Stretch E with Evan in the back while Tony heads there separately with his driver Costas.
Word got out around town of the deal, and Ray Boccino hired Johnny Klebitz to intercept the deal and steal the diamonds. Johnny and some members of the Broker chapter of The Lost Brotherhood arrived and ambushed the deal, forcing Tony, Luis and Costas to escape in one car and Evan with a couple of unnamed associates of Tony's.
Evan flees with the diamonds while being pursued by Johnny and some other bikers, bleeting online from within the limo. Eventually, Johnny destroys the limo, and Evan attempts to escape on foot, only to be gunned down by Klebitz. His last known words, delivered by Bleeter, were "Cornered by bikerz. Eugh. Eugh. Eugh. 2 young 2 die".
