Then I wiki'd Serpentor and sure enough, you were right. Didn't remember dude at all.

"Serpentor was designed to be the ultimate Cobra leader. Under the direction of Doctor Mindbender, he and Destro combed the tombs of the greatest leaders in history to find cells with DNA traces. These long-dead genetic blueprints were combined to produce a clone with the genius of Napoleon, the ruthlessness of Julius Caesar, the daring of Hannibal, and the shrewdness of Attila the Hun. Serpentor is a brilliant tactician and a master of political intrigue, and was eventually capable of wresting power of Cobra from Cobra Commander."
