Klaar was the head of Prisoner Planet. Klaar reprogramed the A.I.'s of dangerous criminal robots for the greater good.
Klaar once mistook Megas for one of his prisoners, but the misunderstanding was soon cleared up. Klaar decided to destroy Megas anyway due to Coop's interference. He had all of the prisoner robots attack Megas using a massive antenna, which Coop destroyed. Ultimately, the criminals were all released thanks to Coop, who thought the robots were being held as slaves by Klaar. However, at least one of the robot criminals' reprogramming kicked back in, suggesting Klaar managed to repair the mind-control antenna.
