Before Kingdom Hearts Union χ
Turbo was once the star of his own game called TurboTime; however, he let all the fame and popularity of his game go to his head. When a new game arrived he got extremely jealous, desperate to get his popularity back he tried to take over the new game but in doing so he caused interference leading to both games crashing for good. His actions resulted in the coining of the phrase "going Turbo."
Unknown to the citizens of Game Central Station, Turbo secretly survived and took over Sugar Rush. Under the alias "King Candy," Turbo hacked the game by removing Vanellope's code which resulted in her being reduced to a glitch and everyone forgetting about her. But aware that Vanellope was still around he made his mission to prevent her from racing knowing that if she won the game's programming would reset to the way it was erasing everything he had done.
Kingdom Hearts Union χ
While the events occur, King Candy was responsible for putting the Heartless in the game's code.
King Candy is a diminutive, elderly man. He is mostly bald, except for a few strands of grey hair. He has fair skin and a large, round head, thick eyebrows, and a bulbous, pink nose. He wears a white shirt with a red bowtie and a prominent collar, a purple jacket, a golden crown, and golden, checkered pants with red tips on his shoes.
As Turbo, he has grey skin and golden eyes, with a normal nose. He wears a white racing suit with red highlights, and has a white helmet with a big, red letter "T" emblazoned on the front.
King Candy first appeared as the main antagonist of the 2012 Disney film Wreck-It Ralph, voiced by Alan Tudyk. He was originally Turbo, the attention-loving lead character from the fictional racing game TurboTime, but when RoadBlasters came and took the attention away from TurboTime, Turbo became jealous and tried to take over RoadBlasters, resulting in both games being taken away. To regain his popularity, he usurped the racing game Sugar Rush from its princess, Vanellope, hacking the game's code to reduce her into a glitch.
In the film, he encounters Wreck-It Ralph after he breaks into the Nightly Roster Race to regain his medal from Vanellope. King Candy orders his guards to throw Ralph out of the game, but Ralph meets with Vanellope and helps her get into the race. When his minions are unable to find the duo, King Candy finds Ralph's medal in the game's code and manipulates him into destroying Vanellope's kart before abducting her. However, Ralph reconciles with Vanellope and frees her. During the race, King Candy discovers that Vanellope has broken free and tries to kill her when she accidentally exposes him as Turbo. She manages to teleport away, and he is eaten by a Cy-Bug, but he merges with the virus. Now believing he can take over any game of his choice the arcade, Turbo engages Ralph in a brief fight before forcing him to watch Vanellope meet her end to the Cy-Bugs, but Ralph breaks free and activates a beacon from Diet-Cola Mountain, which Cy-Bugs are weak to. Though Turbo tries to resist the Cy-Bug's instincts, he ultimately succumbs and perishes.
