King Candy

Turbo, simply known as King Candy is the primary antagonist of the 2012 Disney film Wreck It Ralph. He was played by Alan Tudyk.

Beginnings
Turbo is the former ruler of the arcade game Turbo Time. When a fancier/more modern arcade racing game called RoadBlasters came in and stole Turbo's thunder, he got jealous. He took the game over for himself. Instead of getting his attention back, however, he had both Turbo Time, RoadBlasters and (presumably) himself put out of order for good. This was a well-known story to all videogame characters and was used as warning to what could happen if someone abandons his or her own game- which would later be referred to as "going Turbo". It turns out that Turbo survived, disguised himself as a character called King Candy and re-programmed the 1997 arcade racing game Sugar Rush to make his new persona the lead character just to get his attention back.

In Wreck-It Ralph
When he notices that Wreck-It Ralph came to this game, he does not exactly welcome him to his homeland with open arms and wants to know why Ralph is game-jumping. His cohorts are Sour Bill, his depressed diminutive lackey, and Wynnchel and Duncan, his two donut cop henchmen. He and the other racers hate a little girl called Vanellope von Schweetz, as they consider her a "glitch" in the game and never let her get the chance of racing in "Sugar Rush." He also hates outsiders that stumble upon his game. He is adored by the Sugar Rush racers, particularily Taffyta Muttonfudge. It turns out he messed with Vanellope's programming and made her a glitch in the game.

Revelation and ultimate death
During the climax, as Vanellope is trying to beat King Candy in the race, King Candy suddenly tackles Vanellope's kart with his, attempting to run Vanellope off the track. The angered ruler tries to kill her by smashing her with his candy cane, but the girl grabs the cane and transfers her glitches to the king while she was struggling with him, causing the king to glitch himself and expose him as his real self from "Turbo Time" in front of Ralph, Felix and the citizens of Sugar Rush. With his identity discovered, Turbo tells Vanellope the truth and attempts to kill her, but she glitches herself and her kart away from certain death. Just as Turbo is about to follow suit, he gets eaten by a Cy-Bug as he was about to make the track, but unfortunately survives his death as Cy-Bugs become whatever they consume, thus becoming Turbo and allowing him to fuse with the Cy-Bug, turning him into a monstrous creature and becoming a virtual virus that will destroy the entire arcade. Cy-Bug Turbo attempts to stop Ralph from wrecking the Mentos stalactites toward the Diet Cola geyser, but Ralph is able to break free from the Cy-Bug Turbo's grasp and finish wrecking the geyser, nearly risking his life in the process. Just when Ralph is about to fall into the Diet Cola lava, Vanellope saves Ralph just in time using Crumbellina's kart. The Cola spews out of the bottle-shaped volcano and attracts the Cy-Bugs and Cy-Bug Turbo to their deaths, vaporizing them upon contact. Since Turbo belonged in his previous game, "Turbotime" (which was out of order for good), and video game characters are unable to regenerate outside from their own video games, he is certainly gone for good.

Abilities
Besides being a notable racer, his ambitions and envy drove him to learn new things and brew up nefarious plots. He's the only videogame character presumed to have managed to crack the Sugar Rush security code (which was a reference to what's known as the Konami code) and re-program it to become the main character, while leaving Vanellope out.

When it comes to physical strength, he is a weakling; but that changes when he is nearly devoured by a Cy-Bug but managed to merge with it, by doing so, he gained strength as well as the ability to fly. Just not the same strength level as Wreck-It Ralph, thus causing Ralph to break himself free from Turbo's grasp.

In Sugar Rush
For the time King Candy portrayed himself as the benevolent lead character, he always gave sweets to its people. He was the character with the best stats, especially in speed, and he was always selected by default. The speedster monarch was specially afraid of Vanellope regaining her place as a racer. She reveals King Candy's true form was Turbo.
