Dr. Wily (Mega Man 6)
Dr. Wily already looks like enough of an idiot when he spends all his time and money making set after set of eight robot baddies, each with competing weaknesses, and sending them after Mega Man. The little blue robot, who has the ability to copy powers, somehow never loses. But after everything, after years of failure, Dr. Wily decides to switch things up a bit. With the power of a pair of sunglasses, Dr. Wily becomes Mr. X, and he tries to set up an innocent robot tournament as a trojan horse to... do that other thing again. This is like that time Hulk Hogan totally wasn't under the Mister America mask, but only slightly less obvious.
