Chaos Knuckles was a transformation achieved by Knuckles in the universe of Dark Mobius. Unlike his Prime Zone self, this version of Knuckles never returned to his normal form, instead retaining all his powers. Using this strength, he eventually defeated Dr. Eggman, but ended up becoming the villainous Dark Enerjak. (SU: #27)
