The Dark Legion is a group in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They were an alternate version of the Dark Legion from Dark Mobius. Like their counterparts, it was an army of cyborg Echidnas.
The Dark Legion's early history was most likely largely the same as its Mobius Prime counterpart's. The point of divergence was during the efforts of Dimitri and Knuckles to reunite their people. Though the joining took place, a rift still existed between the two groups, and served as one of the many factors that pushed Knuckles along his path to becoming Dark Enerjak. In his efforts to bring the world to order, he eventually took over the Legion as his own personal army, replacing one of his eyes with a cybernetic implant as a token of good faith. However, the Legion became increasingly rebellious at his tactics of conquest, and Knuckles eventually grew tired of what he believed to be ineptitude on their part. The Dark Legion's ultimate fate is unknown.
