Anyone who's ever played ANY Megaman game, even with invincibility on, knows that SPIKES ARE FRIGGING EVIL.
If I were Dr. Wily, I would just make a robot and cover him in spikes. Then I'd program in a random move generator so he wouldn't go in the same moronic patterns, and send him to kill Rockman, Roll, Blues, Beat, and yes, even fucking Forte. That traitorous bastard!
