Sour Bill

Sour Bill is King Candy's diminutive minion and a secondary antagonist in the film Wreck-It Ralph. He is voiced by Rich Moore.

Official Disney Bio
As King Candy’s diminutive henchman, Sour Bill is often left to handle the stickier situations—but this long-faced little ball isn’t exactly happy about his depressing duties.

Info
Sour Bill is King Candy's most trusted assistant, who speaks with a deep, monotone voice. In contrast to his king who is very eccentric and over the top, Sour Bill tends to be rather gloomy and depressing, with a sour deposition. Even so, when Ralph meets King Candy and his minions for the first time, the king and Sour Bill apparently thought with the same mentality judging by their similar reactions in the scene. By orders of King Candy, Sour Bill is forced to handle difficult tasks in the Sugar Rush kingdom, much to his dismay. Sour Bill was the closest one to the king during his reign, being the only other character to know about the secret codes of the game that were hidden in the castle. Bill was also the only one to know that King Candy was not keeping Vanellope from racing to keep the game safe, which is what the king told everyone else in the kingdom.

An interesting note is that it was originally believed that Sour Bill was gloomy as a result of a strong disliking towards King Candy. However, this is not the case. Not only was he shown to be loyal to the king, albeit annoyed with some of his orders, Sour Bill continues to appear depressed even after Candy's death, as seen when he announces Vanellope's royal status, declaring her the rightful ruler of Sugar Rush, unenthusiastically. This could possibly mean, Sour Bill's gloomy attitude is part of his programming.

Wreck-It Ralph
In the video game kingdom of Sugar Rush, the racers of the game are preparing for the daily Random Roster Race which determines which racers will be playable for the day. Sour Bill is first seen presenting his majesty King Candy. After the racers deposited their coins, Sour Bill and King Candy notice a mysterious racer depositing a coin. The racer is Vanellope, who was banned from racing because she is said to be a glitch. The king orders his guards to capture her, but a taffy monster attacks, and the guards are only able to catch it instead.

The monster is taken to King Candy's castle. Sour Bill de-taffys the monster who is revealed to be the bad guy from the game "Fix-It Felix, Jr.", Wreck-It Ralph. Ralph claims that the coin Vanellope deposited was actually a medal he earned from the war game "Hero's Duty". The king claims he's unable to return it as it was now in the codes. Ralph is kicked out and the king goes off to search for the glitch. Later on, when the search is a failure, Sour Bill and the king travel to a hidden part of the castle, where a secret realm containing the game's codes lie. Judging by Bill's fearful expression when he and the king enter the codes, it's not a place he's very fond of.

Sour Bill holds the king using a rope as the king swims into the codes and receives Ralph's medal. Sour Bill is then left in charge while the king went out to find Ralph. During the king's absence, Sour Bill is visited by Fix-It Felix, Jr., who is searching for Ralph. Bill immediately locks Felix up in King Candy's fungeon, not wanting him to be a threat to the king like Ralph was. Later on, Sour Bill is out cleaning up the shattered remains of Vanellope's kart, just when he's confronted by Ralph. Ralph demands to know why Vanellope was on the game's cabinet despite the supposed fact that she's a glitch. Bill tries to keep quiet but Ralph begins to lick him, threatening to eat him.

Horrified, Sour Bill finally confesses. He tells him that Vanellope was a racer, until King Candy messed with her program and tried to delete her code. When Ralph asks about the king's motives, Sour Bill is unable to answer as the memories of everyone in the game were locked up by the king. Bill then tells Ralph that if Vanellope crosses the finish line, the game would reset and she will no longer be a glitch. Ralph then spares Sour Bill and sticks him on to a giant lollipop tree. When Vanellope crosses, Sour Bill and the other inhabitants regain their memories, and Sour Bill declares Vanellope the rightful ruler of Sugar Rush.

 * He's true to his name Sour Bill in two ways:
 * He has a sour deposition.
 * He actually tastes sour, according to Ralph.
 * With the film showing no signs of Sour Bill being a bumbler, Sour Bill proves to be one of the few competent Disney villain henchmen.
 * It is unknown how Sour Bill was aware of King Candy's crime of locking away the memories of the inhabitants, being that his memories were locked away as well. However, it is possible that King Candy had told him to prevent anyone else from becoming suspicious.
 * Sour Bill can be considered the first minor antagonist who puts a protagonist into bondage (in this case, Fix-It Felix Jr.) A great bunch of Disney Villains like Jafar with Aladdin, Syndrome with Mr. Incredible, Captain Hook with Peter Pan or Wendy, etc., are the main antagonist for their respective films.
 * As seen in The Art of Wreck-It Ralph book, Sour Bill was originally meant to have limbs. Also, in some concept art, he was seen as a red candy ball as opposed to the green candy ball he is today.
