Quote:...Swarm (for the high camp factor of a villain consisting of a Nazi skeleton and a swarm of killer bees)...
Swarm is the one that immediately came into my mind. Killer Bees was a "buzz" word that instantly struck fear into kids in the late 70's; so much so that he/it really left an impression on my young mind.
After that I took a few seconds to actually contemplate the question and the next villain that came to mind was Arnim Zola - just a fantastic visual by The King with the camera head and flat screen face.
I wish I thought of Arnim Zola. Those Kirby issues with Zola and Doughboy really struck a nerve with me when I when I was 7. Nowadays, writers try to make everything believable and they forget how great the fantastic can be.
