 is an idiotic Italian plumber who is SMG4 and Meggy's best friend, Luigi's older twin brother, SMG4 and SMG3's avatar, the designated hero (a loose term, albeit not originally) of the Mushroom Kingdom, Bowser's former arch-nemesis, Princess Peach's former love interest, and the co-leader of SMG4's Gang. Mario is an immensely dumb, narcissistic and troublemaking person, and despite his good intentions, his selfish and stupid behavior often antagonizes and ruins people's lives.
