Mario’s going on a roll now. It helps that he may very well be the strongest Nintendo character. Whyyyyyy! Well Mario probably can’t wait for his fights to keep coming. Mario wins.
Update! I think Ness’s psychic powers will prove to be too much for Mario. Mario is a good close range fighter, but he won’t be able to cope with the long range attacks. Ness wins.

Ness has universe busting power and is the 2nd most powerful nintendo character.Marios doesent stand a chance
Ness is extremely powerful so I can’t deny that he would throw in some epic blows, but I’ll need to see more of this universe busting ability.
