Fang hails from an unidentified alien race of beings with lupine traits from which one member is chosen to bear the name and wear the costume of Fang in the Imperial Guard. Fang was 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. He was amongst the first of the Imperial Guard encountered by the team of superhuman mutant adventurers known as the X-Men who sought to rescue the Princess-Majestrix Lilandra from her insane brother, then-Majestor D'Ken. Following the orders of their emperor, the Guard clashed with the X-Men and were on the verge of winning when the band of interstellar freebooters known as the Starjammers arrived to turn the tide of battle in the X-Men's favor.

Fang was later amongst those Imperial Guard members who allied themselves with the treacherous Shi'ar High Council member Lord Samédàr who was aiding an attempted coup of the Shi'ar throne by Deathbird. Even after the ploy was discovered, Fang, like most of the other Guard members present, still chose to side with Samédàr against the team of superhuman mutant Earthlings known as the X-Men who were defending then-Empress Lilandra. However, Fang's choice ultimately resulted in his death after he was implanted with an egg from the alien Brood on their home planet known only as "Broodworld". As with all Brood hosts, he was utterly consumed by the infant alien when it hatched from within him.
