Blimp 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, Blimp was involved in the Guard's attack on the team of superhuman mutantmutant 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, Blimp's suit was ruptured by the feral clawed X-Man named Wolverine, allowing him to be easily defeated by the Beast. It is unknown whether Blimp survived.
