Wreck it Ralph

Have some candy!"

―King Candy's signature phrase

King Candy, also known as Turbo, is the main antagonist of Disney's 2012 animated film Wreck-It Ralph. He was the false ruler of the kingdom in which the game Sugar Rush takes place. He is voiced by Alan Tudyk.

All hail King Candy, ruler of the race track, captain of confectionery, sovereign of sugar. Not surprisingly, the most powerful figure in the Sugar Rush game is also the best racer on the track. He may look noble enough, but don’t be fooled. This mysterious monarch rules his kingdom with a sugary fist and he is determined to keep his kingdom safe from glitches, rabble-rousers and outsiders. Don’t expect him to go easy on Ralph and Vanellope. The King is ably assisted by his strong-arming security donuts, Wynchel and Duncan, and his diminutive henchman Sour Bill, a tiny little ball of un-sweetness.

Personality

King Candy is incredibly eccentric and flamboyant. Throughout most of the film, he portrays himself as a bubbly, yet somewhat strict, ruler. As Turbo, he was said to have loved the spotlight, but the moment that was all taken away, the racer became demented, and he was determined to remain beloved, even if it meant ruining another game. While most of the film portrays him as wacky and fun, the king's true colors are shown as time goes on. He is revealed to be a villainous mastermind, whose ambitions drive him to insanity. According to his minion, Sour Bill, he'll do anything to get what he wants. This was when Sour Bill explains that King Candy tried to delete Vanellope from the game years before and was proven again when he attempted to murder her on the racetrack during the Random Roster Race. It is traits like these that makes King Candy a virus, what video game characters christen as dangerous threats that can spread and control. Like most Dysney Villians, King Candy is power-hungry. This was shown when he was turned into a monstrous Cy bug, as he openly planned to take over any game of his choice, now that he had ultimate power to assimilate.
Although he was a strict ruler, Candy was apparently beloved by the Sugar Rush subjects, who all showed a definite respect for him, with the exception of Vanellope of course. The praise, however, was in reality artificial when Turbo had reformatted Sugar Rush years ago. He was particularly close to Sour Bill, his most trusted assistant, who was found by the King's side regularly. Sour Bill was the only other character in the film to know about the secret codes of Sugar Rush, and was trusted by Candy enough to know that Vanellope wasn't really a glitch, as well as the fact that Candy locked away the memories of the inhabitants of the game, and the overall fact that King Candy was truly villainous as opposed to the bouncy benevolent ruler he portrayed himself as to everyone else. Aside from his dark, yet humorous nature, King Candy also proves to be very manipulative, being able to get Ralph to destroy Vanellope Kart acting as if it was to protect her, though it was really to prevent his plans from being foiled. He also showed signs of being a sadist, specifically when he laughed psychotically when Vanellope was about to meet her end on the race track, again when he stated killing Ralph would be more fun than gratitude, and again when he forced Ralph to watch Vanellope as she was nearly killed by a swarm of Cy-Bugs, exclaiming "Let's watch her die together, shall we?"
One of King Candy's most notable traits is his random giggling that occurs either in between many of his sentences no matter what mood he's in, whether it be ecstatic, enraged, surprised, and so forth.
But what it comes down to, is that King Candy is among Disney's most depraved and evil villains, who is willing to do whatever he must to secure fame and power for himself, even if it means destroying games and killing, and is a most devious manipulator.
