Nega-Liquidator is the good counterpart of Liquidator, living in the Negaverse. He's a mutant dog. Just like his evil counterpart, he has superpowers and can thus control water as well. He is part of the Friendly Four and fights the forces of evil, especially Negaduck.
Once Negaduck is defeated, he becomes one of Nega-Gosalyn's guardians.
He was voiced by Jack Angel.
