This one from "Creature From the Haunted Sea" (1961) may just be my fave. Check him out:
Some of my faves: Blood Freak (Turkey - headed Marijuana monster.) , Dracula Vs. Frankenstein - 7'4" Accountant , John Bloom , wearing a gloppy mask reportedly designed by a well - intending teenager , kills both our Fearless Leader , Forrest J. Ackerman (The reason we HAVE Horror and Sci - Fi fandom , today.) , and gets killed by the Arabic - looking "Zandor Vorkov", who speaks in echo , and wears silly proto - "Corpse Paint" to complement his goatee and curly black hair. The monster's death scene was lampooned in "Monty Python and The Holy Grail". A member of the troupe confessed to this (After they got out the comfy chair...).Day The World Ended (3 Eyed , horned monsters! YEAH!) , Monster from Piedras Blancas (Surely the first movie to display bloody severed heads.) , Creature With The Atom Brain , The Colossus of New York (Neither of which deserve their "B" status.) , The Green Slime , The Thing With Two Heads , The Hideous Sun Demon , Santo and Blue Demon Vs. The Monsters ( The Frankenstein monster is a guy wearing a Don Post Frankenstein mask , with a Zapata moustache and a Beatnik beard. Also , he can drive a car.)
I'll say "any monster other than The Beast With A Million Eyes."
