Ive read about a few alternate Knuckles that ive never even scene before (or herd of in refrence) and was wondering if these were true alternates, or just made up. One thing was a possible 'future'. Brass Knuckles? The second wasnt given a name, but was said to be a cheif of police in the same universe as Sally McAcorn. The last was somthing about a giant mutant with three spikes on his hands.
