- “Okay. Producer Zachary back on the mike. Is this... Is this even working? Everything's Vespucci about the station, except the equipment. Ah, don't get me start on that annoying little shit I got it from in San Fierro. Loser, total zero.”
- — Zachary
He is Julian Casablancas' producer and hosts the Kult FM rock station along with him, Mac DeMarco and Tony Mac. While it is advertised as being hosted by Julian Casablancas, most of the continuity on the station is provided by Zachary, who makes regular reference to Julian's absence.
Zachary states that they built the radio station's broadcast studio themselves with equipment bought from a radio store in San Fierro. He also mentions the the radio store owner being "a loser, a total zero" and having the most annoying voice he ever heard. This references Zero, a character in Grand Theft Auto: San Andreas (also portrayed by David Cross), who owns a RC store in San Fierro.
- Occasionally, Zachary will introduce the Ramones' song "Time Bomb" by saying "Hey ho, let's go Ramones!", a reference to another song of theirs, "Blitzkrieg Bop".
