A new cadidate has entered the race! Sleestak from Lady, That's My Skull. He wants you to know that he is the master of a dimensional world, has several advanced doctorates in arcane science, and is being able to journey between dimensions at will, and has also mastered time travel. Quite a resume!
Dr. Zira, I must caution you. Experimental brain surgery on these creatures is one thing, and I'm all in favor of it. But to suggest that we can learn anything about the simian nature from a study of man is sheer nonsense. Man is a menace, a walking pestilence. He eats up his food supply in the forest, then migrates to our green belts and ravages our crops. The sooner he is exterminated, the better. It's a question of simian survival.
