Eventually, the Oans discovered N'Lasa's part in the rebellion and brought him before them for judgement for his crimes. As recompense, he offered his own life and head to the Guardians as punishment for his actions though they refused and spared him. However, they attached a condition to him which was exile to the planet Earth where he was to remain for the rest of his life. To ensure he did not die a normal lifespan, the Oans greatest scientists conducted surgery on him that cybernetically as well as genetically altered him to give him longevity thus allowing him to survive for thousands of years and gave him advanced healing capabilities. Part of his task was also tame the Manhunters and ensure they did not rampage out of control whilst in hiding.
