Etydion (The Custodians)

This Etydion was the last known survivor of his race following the destruction of the Etydion homeworld. He had made his way to Earth by the year 2050. On the verge of death, he offered himself to The Department, which kept him alive and implanted his DNA in VR headsets, distributing them across the British Isles disguised as a 6D video game called Little Green Men. The Etydion used his abilities to make children all over the world obedient. However, the children soon began mutating, as the Etydion had decided to revive his race through them. His telepathic abilities prevented Starkey, Thorne, or even K9 from doing anything to stop it. In the end, it was June Turner's sorrow over what was happening to her daughter that convinced the Etydion to stop. Reversing what he had done to the children, the Etydion seemed to die, an orange energy leaving his body soon after. (TV: The Custodians)
