The diminutive Fader is a member of the Imperial Guard, a multi-ethnic group of super-powered alien beings who act as enforcers of the laws of the Shi'ar Empire. Part of the division of the Imperial Guard known as the Superguardians, Fader was involved in the Guard's first strike on the team of superhuman mutant adventurers known as the X-Men after his Empress Lilandra, under the mental control of Charles Xavier's mutant twin sister Cassandra Nova, had ordered the destruction of all mutants on Earth.
In the ensuing clash, Fader attempted to use his abilities to defeat the Beast, but underestimated the hirsute X-Man's hyper-keen senses and was rendered unconscious.
