Captain Zantor Peace loving leader from the Planet Kalador, Captain Zantor appeared in the Space:1999 episode "Earthbound" one of the finest episodes produced for the series. The Mego uniform is a very close likeness, he comes barefoot but I am sure he had shoes in the episode. Variations of Zantor exist, one has light blonde hair while the other has the correct white hair. Neither variation is more valuable than the other.
As you can see by the above carded Captain Zantor he is a white haired version while the loose figure is a blonde
Actor Christopher Lee is not really known for playing peaceniks like Zantor, he is best known for his work as Dracula in the Hammer series of movies. He is currently working on the new Star Wars film, so chances are Christopher Lee figures will be available again but Mego got there first.
