Some time later, Trogg used the Dark Orb to summon the Dark One again in order to transform the other Enchanter Kings in the same way as he had been. The Dark One demonstrated incredible power, effortlessly incapacitating Tails, Knuckles and Morain. It successfully transformed the Enchanter Kings into monsters like Trogg, but was destroyed (and the transformations reversed) when Tails threw the Dark Orb into the "non-existent space" below the Dimension Bridge.
"Dark One" and "Evil One" are merely titles. Trogg also once referred to the being as "the one whose name is never spoken".
