In Grand Theft Auto: San Andreas, Ice-T voiced the rapper Madd Dogg. Madd Dogg is a famous Los Santos performer whose career and confidence collapse after OG Loc steals his rhyme book and takes credit for his work.
CJ eventually helps Madd Dogg recover his mansion, rebuild his reputation, and return to the music business. The character is part of the game's wider satire of the Los Angeles rap scene, where rivalries, image, commercial success, and street credibility overlap. Ice-T's casting adds another layer because he was already an influential rapper and actor before appearing in the game.
A common mix-up is Snoop Dogg, whose persona reportedly influenced aspects of Madd Dogg's characterization but who did not voice him. Nate Dogg and Dr. Dre are also strongly associated with the game's soundtrack and hip-hop world, yet neither provided Madd Dogg's voice. Ice-T's performance was retained through archival recordings for the later Definitive Edition of San Andreas.
