At some point, either when or before Kang declared war on Earth, Glomm rebelled against the deviant empire and aligned himself as a soldier serving under Dulpus. He became the chosen champion of Dulpus.
When the Avengers had chased an army of deviants into their underground lair, they were surrounded on all sides by hundreds of deviants. Taking advantage of the Deviants own rules, Warbird challenged the deviant leader, Dulpus, to combat for the right to rule. Dulpus eventually agreed despite the fact she was human and female, under the stipulation that if she lost, she would become his body-slave.
