Whenever Litwak's Arcade closes, the various video game characters leave their in-game roles and socialize via a power strip they call Game Central Station. Wreck-it Ralph, the main antagonist of Fix-it Felix, Jr., visits a villain support group called Bad-Anon and expresses frustration with his assigned role. When Ralph is excluded from the game's thirtieth-anniversary party, he determines to win a medal and earn respect. Upon overhearing that one can earn medals in the first-person shooter Hero's Duty, Ralph sneaks in and steals one while the characters fight insectoid monsters known as Cy-Bugs. Ralph accidentally launches himself in an escape shuttle with a Cy-Bug inside and crash-lands in the candy-themed kart racing game Sugar Rush. With Ralph gone, his game is labeled out of order. Felix leaves the game to find Ralph, allying with Sergeant Calhoun, the heroine of Hero's Duty, as she tracks the Cy-Bug, which may become a virus.
