The character was described in his debut as being the sum total of the hatred of "a billion billion beings" and the sole survivor of an alien species who attempted to invade
Asgard before
Odin stopped them. Imprisoned beneath Asgard, Mangog is freed by the rock troll
Ulik, in a failed bid to secure an ally against the gods. Mangog storms Asgard, intent on obtaining the
Odinsword to destroy the universe. Thor battles Mangog to a standstill, until Odin stops him by breaking the spell which had created Mangog as a living prison for his entire race. Mangog is later freed by
Loki, but defeated after being drained of his power. With the aid of the traitorous magician Igron, Mangog assumes the form of an imprisoned Odin, and intends to once again draw the Odinsword. After a series of skirmishes with Thor, the creature is defeated when Thor frees Odin. The character reappears twice in the second volume of
Thor: as the servant of a clone of the Titan
Thanos (destroyed by Thor) and in a desolated Asgard during
Ragnarok (dispelled by Thor with the Odinforce) Mangog reappears in the
Thunderstrike mini-series when accidentally summoned by a mystical generator, and is eventually defeated when cast into a distant star. In
The Mighty Thor, Mangog decimates Asgard until
Jane Foster / Thor throws him into the sun. He later absorbs
Mjolnir's power and becomes the God of Hammers before Thor fatally drains his energy. ==Powers and abilities==
