Captured by barbarians and turned into a slave, Attuma would become a barbarian as well. He went on to conquer Lumeria and became its ruler.
Lumeria became a part of Kang the Conqueror's Chronopolis and became a location where one of the shards of the Nexus of All Realities ended up at. When the Avengers tried to retrieve the shard, Attuma lured them into a trap and sent them to the Sakaar sector of Chronopolis. The Avengers later returned and battled Attuma and his forces for the shard. Attuma was ultimately defeated.
