Cy-Bug

Cy-Bugs are creatures from Cy-Bug Sector in Kingdom Hearts Union χ. They originate in the film .

Origin
Cy-Bugs made their debut in the film . They are viruses that hail from the game Hero's Duty. Because they are mindless and cannot distinguish the game from reality, they are potentially lethal to Litwak's Arcade, forcing the soldiers of Hero's Duty to fend the beasts off every day.

During the events of the film, Wreck-It Ralph first encounters the Cy-Bugs after learning that he can get a medal in Hero's Duty. Though he acquires the medal, he accidentally hatches a baby Cy-Bug and, in his attempt to fight it off, sends it and himself to the racer Sugar Rush. The Cy-Bug manages to make a nest in the game and eventually amasses an army upon the game during its Nightly Roster Race. During the chaos, the original Cy-Bug encounters and eats the game's despot, former game star Turbo, but he fuses with the Cy-Bug and intends to unleash the virus upon the arcade. Because Cy-Bugs are weak to destructive beacons, Ralph is able to subdue the Cy-Bugs by creating a beacon on Diet Cola Mountain.
