Sir Charles Hedgehog, formerly known as Dr. Charles the Hedgehog, is a character in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He was the alternate version of Sir Charles Hedgehog from Dark Mobius.
Charles' early history was most likely largely the same as his Mobius Prime counterpart's. The point of divergence was when Knuckles became corrupted by his chaos powers and decided to conquer Mobius. At some point, he became involved in the resistance against Knuckles, now having assumed the mantle of Dark Enerjak. Cutlass Depardieu wrote to Jani-Ca, leader of the Dark Freedom Fighters, to connect her with Chuck so that his Roboticizer technology might be utilized on behalf of injured resistance fighters. The most notable example was Blockbuster Polar Bear, who had nearly his entire body Roboticized.
