Bluefur is a member of the Toxic Mutants, a race of beings made from noxious chemicals generated from humanity's pollution. They bear a hatred towards mankind, both for creating them and leaving them aloof as outcasts of society. As such, when Vrak arrives and offers him and Bigs a chance to ally themselves with him, they promptly accept and, from then on, carry out the war against the Megaforce. By doing so, they indirectly become comrades to Malkor as well. He is one of 2 Quaternary antagonists in Power Rangers Megaforce.
