Miek was a member of the Natives, an insectoid race believed to be the only sentient people truly native to the planet Sakaar. Despite being the true native race, the Natives were victims of the red-skinned, humanoid Imperials. This was a truth Miek experienced directly when he was quite young. His father and hive were slaughtered by a unit of Imperials by the order of the Red King. The Red King desired the hive's land and resourced, which were granted to Miek's hive by the previous emperor for his father's honorable service in the Spike War. Miek survived the slaughter only to be taken as a slave.
To this end, Miek entered into a fifth stage of evolution that was rare for any Native to reac, but he did so because he hive called on him to. When he emerged from his cocoon, he was many times larger and more powerful than before. He was now King Miek, the official leader of his hive. He convinced Hulk that they had to overthrow the Red King. The Red King had to pay for all his crimes, including sending the Spikes, a parasitic alien horde, after them.
