“The well-known hero of the Mushroom Kingdom was once a plumber in Brooklyn who stumbled across a Warp Pipe that lead him to the kingdom, along with his younger brother Luigi. With his amazing jumping skills and useful supply of power-ups, Mario will see to it that the job get done, no matter how difficult!”

“Mario's cape can reflect pretty much any projectile in the game, big or small, bomb or bullet. Use it only a second before Mario gets hit to return it back to sender with double the damage and knockback! Also good for preventing recoveries if you're skilled enough.”
— Unlocked by winning 100 matches as Mario.
Mario Finale (Final Smash)

— Unlocked after beating All-Star Mode with Mario.
Mega Mario! (Final Smash)
“Mario becomes larger than life and big enough to shrug off anything his opponents can throw at him! He can use any of his attacks, but that's no big deal since he can hurt people just by walking into them! If Mario gets this Final Smash, make sure you don't get caught underfoot!”
— Unlocked after unlocking all of Mario's custom moves.
