The Pacman Ghosts, of course.
The ONLY thing that could maybe defeat(sort of) them is Pacman.
And since he isn't on the list, there is no one, who is a thread to them.
In the end they always win, and Pacman always dies...
But the abillity to build mazes could keep them in check... for science. These monsters. ^^
Team Rocket, Dr. Robotnik, M.Bison, Bowser are mere mortals with some gimmicks.
Sephiroth is(though powerfull) a little emo boy with mother issues.
And the "Lich King"...
Well, just brake his sword...
For which again you need only 10-25 people out of the millions available...
