Mystique is a character in mentioned in the Vice City Inquirer, the manual for Grand Theft Auto: Vice City Stories. Mystique is a prostitute who lives in Downtown Vice City. In 1984, at the age of eighteen, she and Destiny won a Vice City Lotto Scratch Off Jackpot of $250,000. She split the money with Destiny, although by the end of the week she had spent her half on spa visits, tube tops, a walkman and 'massive amounts' of pharmaceuticals. After two weeks, Mystique returned to prostituting. She tells her story to the Vice City Inquirer.
- Mystique looks similar to a Grand Theft Auto: Vice City Stories in-game prostitute and multiplayer character Dee Generate.
- Since the game is set in 1984, her name is possibly a reference to a game company that made many pornographic video games for the Atari 2600, some of which are Custer's Revenge, Beat 'Em and Eat 'Em, and Bachelor Party. However, it is more likely that she is named after the shapeshifting mutant of the same name from the X-Men comic books, due to her assocation with a character named Destiny (which is also the name of an X-Men character).
