The Cy-Bug Queen is the main antagonist and the final boss in Wreck-It Ralph: The Video Game. This robotic monster is the leader of Cy-Bugs. The Cy-Bugs hatch and immediately begin to attack Sugar Rush, eventually heading into Game Central Station. Vanellope and Calhoun evacuate with the other denizens while Ralph and Felix are given the task of destroying them.

Ralph and Felix journey off into Fix-It Felix, Jr., Hero's Duty, and Sugar Rush to eradicate the bugs, eventually being led to Game Central Station, where they defeat the Cy-Bug Queen through the use of massive grappling guns. After the bugs are defeated, Ralph heads to Sugar Rush to celebrate the new holiday made by Vanellope, and then returns back to his own game.
