Dwaine, also spelt Dwayne, is a character in the Grand Theft Auto series as a minor character in both Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. Dwaine was voiced by Navid Khonsari in both GTA Vice City and GTA San Andreas.
Dwaine is a mechanic who can normally be found with his friend Jethro. In 1986 Dwaine, along with Jethro, reside in Vice City and hang out at the Boatyard and he appears during the purchase of the Boatyard, though unused audio file suggest he and Jethro also appeared in The Fastest Boat in the beta. When Tommy Vercetti buys the Boatyard it is presumed that Dwaine, along with Jethro, leave Vice City and head towards San Andreas.
By 1989, Dwaine and Jethro are in San Fierro and eventually meet The Truth at the '89 San Fierro Love In and have become friends with The Truth whom they bought drugs from. Dwaine soon began running a hot dog van  until 1992, when he is recruited by Carl Johnson to work at his garage as a mechanic.
