Hussar is a former 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. Hussar was one of eight Imperial Guardsmen chosen to battle the team of superhuman Earthling mutants known as the X-Men over the fate of Phoenix, a primal force of the cosmos that had assumed the form of the X-Man Jean Grey.
Hussar 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, Hussar, like most of the other Guard members present, still chose to side with Samédàr against the X-Men who were defending then-Empress Lilandra.
Later, after the formerly-exiled Deathbird had usurped the Shi'ar throne, Hussar was amongst those Imperial Guard members who clashed with the British team of costumed adventurers known as Excalibur and the team of interstellar freebooters known as the Starjammers over the fate of the then-bearer of the cosmic Phoenix Force, the alternate future daughter of the X-Man Jean Grey named Rachel Summers.
Much later, during the war between the Shi'ar and Kree Empires, Hussar was amongst a small contingent of the Imperial Guard that defended Lilandra, who had since regained the throne, against the Kree super-team known as Starforce. Hussar was also amongst those Imperial Guard members who defended Lilandra against an assassination attempt by the Kree Ronan the Accuser and his unwilling agents, the royal family of the Earth race known as the Inhumans.
Following a meeting of the intergalactic council, Earth was declared a threat to the entire cosmos and consequently it was deemed to turn the planet into an intergalactic prison. Criminals from numerous alien races were teleported to Earth, among them the former Imperial Guard members who had allied themselves with Deathbird and Lord Samédàr all those years ago. These former Guardsmen had allied themselves with a lone member of the alien D'bari, calling himself Starhammer, who sought revenge on Jean Grey for the crimes of Dark Phoenix.
