Jigsaw is a character from Action 52, a multicart platformer which is considered to be the worst game on the NES. He should totally appear in SSB4, since he was on the NES.
Side B: Saw
Up B: Ladder
Down B: Nail Gun
Final Smash: Glitchy Crash- makes every character freeze for one minute.
Game Breaker- on the NES stage, the cartridge can be removed with one hit, and Jumpman, Classic Link, Donkey Kong, and Mega Man will stop moving. The screen may also turn black during battle. Similar to R.O.B.'s ability.
