History
Hogun was one of the Asgardian warriors who battled alongside Thor, Loki, Balder, Fandral and Volstagg during the celebrations of the end of the war between the Asgardians and the Frost Giants.[1]
Years later, he defended Asgard against the Nazi invasion at the hands of Loki, and died.[2]
In modern times, he was resurrected along with the other Asgardians, but died like the rest at the hands of the Children of Tomorrow[3] and remained as a ghost (as did the rest of the Asgardians) which only Thor could see. He informs Thor that, being the last living Asgardian, he has become Valhalla.[4]
