Dimitri the Echidna (one of two individuals to assume the name of Enerjak) originally served as the Dr. Ivo Robotnik-counterpart to Knuckles the Echidna in the fictional universe of the Sonic the Hedgehog Archie Comics. However, in later issues his role as an antagonist comes to an end, as his previously villainous intentions for domination are replaced by more noble desires, such as reunifying the Dark Legion founded by his descendants with Echidna society.
