Brainiac
And the winner for gayest looking villian of the Silver age is... Brainiac, Vril Dox!  Seriously, I mean the guy wore a pink long sleeved polo shirt, black Daisy Dukes, and white go-go boots.  You do the math.  Any way, I had to make a custom of this guy if only because he was a member of the Legion of Doom on the old "Challenge of the Superfriends" show.  I built him using a Flash body and a Lex Luthor head.  After boiling and popping Lex's head on the Flash body, I remove the boot wings and lightning bolts off of Flash's arms with my Dremel.  Next, I sculpted on Braniac's belt, his collar,  and the computer nodes on his skull with Sculpey.  Finally, I  primed the figure and painted it.
