Dr. Miguelito Loveless
But only the Michael Dunn version from the original Wild Wild West. Dr. Loveless was a deranged megalomaniac who wanted to take over the world just to make it a better place. He proved that you could be an evil genius and still be a perfect gentleman.

wonderful maniacal laugh whenever she had done something evil, which was frequently. She would laugh until she had to suck in air to continue laughing. It was cute as a puppy.
The Brain (Pinky and the Brain)
Brain: We must prepare for tomorrow night.
Pinky: Why? What are we going to do tomorrow night?
Brain: The same thing we do every night, Pinky - try to take over the world!
