Rancis Fluggerbutter is a secondary character of Wreck-It Ralph. He is a racer in the racing game Sugar Rush, and is shown to be close friends with Taffyta Muttonfudge and Candlehead. He is somewhat vain in terms of personality. He is voiced by Jamie Elman.
After Sugar Rush closes for the day, Rancis and the other racers take part in the Random Roster ceremony, held by the ruler of the game, King Candy. They pay their fees for the Random Roster Race in the form of a gold coin, but a glitch in the game, Vanellope von Schweetz, sneaks into the ceremony and also pays her fee with Wreck-It Ralph's medal. After Vanellope escapes capture, Rancis is among the racers that follow her to a junkyard, where she's building her scrap-made kart. The racers destroy her kart in an attempt to keep her from racing, but Ralph sees this and angrily chases Rancis and the other racers out of the junkyard.
Rancis later participates in the Random Roster Race, but Vanellope enters the race in a new kart. Rancis notices her racing and alerts Taffyta, who orders Candlehead to light the cherry bombs at the side of the mountain to blow her off track. However, Vanellope glitches in front of the three racers, distracting them and causing the trio to plummet into an ice cream sundae. A swarm of Cy-Bugs attack moments afterwards, forcing Rancis to flee along with the other inhabitants of the game. He later returns after the swarm is destroyed just as Vanellope crosses the finish line, restoring her status as princess. A horrified Rancis tries to minimize their bullying of her, stating they were only joking, and Vanellope forgives them.
