Think about it though, Corrupted Samus was created from the Phazon, while Dark Link was created from a spell a evil wizard casted at the end of Zelda II? Not to mention, Dark Link is free in OoT, while Dark Samus actually provided a hard fight and was the final boss of the prime games, also take SA-X into consideration, and what happened in Fusion. How you can't even KILL SA-X until nearing the end of the game.
