Cy-Bugs are characters in Kingdom Hearts Union χ.
Cy-Bugs are mechanical creatures that have traits similar to Earth arthropods. They usually have a deep grey coloration, although a few variants are brightly colored. While most Cy-Bugs are terrestrial, few have developed large wings for flight and aerial combat. Cy-Bug hatchlings are smaller versions of their fully-developed form, having a bright green carapace.
Cy-Bugs made their first official debut in Disney's 2012 animated film, Wreck-It Ralph as the main antagonists of the fictional video game Hero's Duty.
