Wreck-It Ralph

When Litwak's Family Fun Center &amp; Arcade closes at night, the various video-game characters leave their normal in-game roles and are free to travel to other games. Within the game Fix-It Felix, Jr., the characters celebrate its titular hero but ostracize the game's villain character, Wreck-It Ralph. At a support group for video-game antagonists, Ralph reveals his desire to stop being the bad guy. Back home, Ralph finds the other characters celebrating their game's 30th anniversary without inviting him. Felix reluctantly invites Ralph to join them, but the others isolate him. They tell him that if he won a medal, just as Felix does in their game, they would respect him.
At Tapper's, Ralph learns he can win a medal in the first-person shooter Hero's Duty. Ralph enters the game and encounters Sergeant Calhoun, its leader. Between game sessions, Ralph climbs the game's central beacon and collects the medal, accidentally hatching a Cy-Bug, one of the game's enemies. It clings to Ralph as he stumbles into an escape pod that launches him out of the game. Meanwhile, with Ralph missing, a girl reports to arcade-owner Litwak that Fix-It Felix, Jr. is malfunctioning. Since broken games get unplugged, leaving their characters homeless, Felix searches for Ralph.
Ralph crash-lands in Sugar Rush, a kart-racing game. As he searches for his medal, he meets Vanellope von Schweetz, a glitchy character who takes the medal and uses it to buy entry into a race. King Candy and the other racers refuse to let Vanellope participate, claiming she is not really part of the game. Ralph helps Vanellope build a kart. At her home in Diet Cola Mountain, an unfinished racing course, he discovers she is a natural racer.
Back in Hero's Duty, Felix meets Calhoun, who warns that the Cy-Bugs can take over any game they enter. As the pair searches for Ralph and the Cy-Bug in Sugar Rush, they separate when Felix, enamored with Calhoun, inadvertently reminds her of her fiancÃ©, who had been killed by a Cy-Bug in her backstory. Calhoun finds hundreds of Cy-Bug eggs underground, and Felix becomes imprisoned in King Candy's castle during his search for Ralph.
Desperate, King Candy hacks the game's code to retrieve Ralph's medal and offers it to Ralph, explaining that letting Vanellope race would be disastrous for both her and the game. Fearing for Vanellope's safety, Ralph wrecks the kart and returns to his own game, but finds that everyone has evacuated, expecting the game to be unplugged in the morning. Discovering Vanellope's image on the Sugar Rush cabinet, Ralph realizes she is an intended part of the game, not a glitch.
Ralph returns to Sugar Rush, finds Felix and Vanellope, and asks Felix to fix the wrecked kart. As the race proceeds, the hatched Cy-Bugs attack and Felix, Calhoun, and Ralph battle them. When Vanellope catches up to King Candy, her glitching reveals that he is actually Turbo, a rogue character from an old game, Turbo Time, who sabotaged a newer game out of jealousy, causing both to be unplugged. Vanellope escapes from Turbo, who is consumed by a Cy-Bug. The group flees the doomed game, but Vanellope finds she cannot pass through the exit. Calhoun says the game cannot be saved without a beacon to attract and kill the Cy-Bugs.
Ralph heads to Diet Cola Mountain, where he plans on collapsing its Mentos stalactites into the cola at the bottom, causing a blinding eruption that would attract the bugs. Before he can finish, Turbo, merged with the Cy-Bug that had consumed him, attacks and carries Ralph away. Ralph breaks free and dives toward the mountain, intending to sacrifice himself to start the eruption on impact. Vanellope in turn uses her glitching abilities to save Ralph. The eruption starts and draws the Cy-Bugs and Turbo to their destruction. Vanellope crosses the finish line, restoring her memory and status as Princess Vanellope, the game's ruler and lead character, while keeping her advantageous glitching ability. Felix and Ralph return to their game in time for Litwak to see it still works, sparing it from being unplugged. Calhoun and Felix marry, and the characters of Fix-It Felix, Jr. gain a new respect for Ralph.
