... and an ugly one at that.
According to GameInformer.com, the game we now know (and love) as Ms. Pac-Man began life as Crazy Otto.
Basically, Crazy Otto was a hack of the original Pac-Man--and was created by MIT students Kevin Curran and Doug Macrae.
Otto looked a bit like Pac-Man, but with legs. And he didn't chase Blinky, Pinky, Inky or Clyde--he chased monsters named Darwin, Freud, Newton and Plato.
Anyway, the story goes that Midway, Pac-Man’s North American distributor, somehow found out about the "expansion," bought it from Curran and Macrae and transformed it into Ms. Pac-Man.
Does this mean we can consider Ms. Pac-Man the first transgender character in video games?
(BTW, a few videos of the Crazy Otto prototype in action can be viewed here.)
