Lupton was a human from 1970s Earth who, having been fired from his job, sought power and revenge. He worked on developing his mental abilities at K'anpo Rimpoche's meditation centre, where he was contacted by one the Eight Legs of Metebelis III to help them find a blue crystal. He later turned against the Eight Legs, but was killed by them. (DW: Planet of the Spiders)
