The Cy-Bug Mother is the secondary antagonist of Wreck-It Ralph. It is a Cy-Bug from the in-universe arcade railshooter game Hero's Duty. A creature created from an experiment gone wrong with no other goal than to eat everything in sight and reproduce. When Ralph visits Hero's Duty to try to get a medal he accidentally brings one into the in-universe arcade racing game Sugar Rush which it then intends to do the same with that game along with its hatch lings. However its consciousness is overwritten by Turbo/King Candy who takes over as the leader of the Sugar Rush Cy-Bugs during the climax.
