Deletion of Doctor Spectro

Comment: I have added a second secondary source. Those together still miss  in my opinion, so as long as noone finds more, I vote for a merge. I think, however, it should not be simply redirected (or even deleted), because the suggested target, Captain Atom#Rogues gallery, would be improved by including the content based on secondary sources
Stance: merge
