Kicks the enemy. Moderate knockback. The entire combo originates from Super Mario 64.
+
Mario does a straight kick. Pushes the enemy back, with short range. While pretty quick, it's lacking in power.
Dash +
Mario slides forward. Knocks enemies diagonally behind him, frequently leads into his +. Very similar to Mario's dash attack from Super Mario 64.
+
Mario sweeps the enemy. Very low knockback, easily punished at damages below 100%. Above 100%, you can follow it up with a forward smash for an easy kill, but it has short range, making this unreliable.
+
Mario uppercuts the opponent. Hits primarily above him; poor forward range. It comes from the second hit of Mario's Mega Glove combo in Super Mario RPG. Great juggler, especially with it's power nerf from Smash 64, and just as good in combos.
Smash +
A short-range fireball. Good range and powerful. Fast, and has decent strength (in terms of knockback, it's the 13th strongest forward smash in the game). However, hitting with the hand is the sourspot.
Smash +
Swings his legs forward and back. Slightly less range and faster than his forward smash, slightly less powerful, but still one of his stronger moves. Comes from Mario's crouch attack in Super Mario 64.
Smash +
Swings his head forward, hitting enemies primarily above him. Low range, but powerful. Has more range behind Mario than in front.
Mario sticks his leg out in front of him. Fairly notable knockback when it first comes out (9th strongest neutral aerial in the game, and the 7th strongest sex kick).
Forward +
Mario swings his fist forward and down. It can spike. Slow, predictable, and has high lag, both on startup and ending. While it has no sourspot, it's relativley weak and not reccomended as an edgeguard, but can combo into his forward or down smash.
Backwards +
He swings his feet behind him. Somewhat fast, decent range, sends enemies sideways. Good for both spacing amd edgeguarding.
+
Mario spins around, hitting enemies multiple times. Mediocre.
+
Mario does a backflip, swinging his leg primarily in front of and above him. Sends enemies up and forward some. Fast, low knockback, great for juggling and comboing.
Mario throws a fireball, which then bounces along the ground, and best used in the air due to this reason. A fairly standard projectile. It can be spammed, with difficulty.
+
Super Jump Punch
Mario uppercuts an enemy, hitting multiple times. Good for recovery and clearing out wireframes, bad for most other real uses. However, it's a great out of sheild attack. Notably, if used next to a wall and the control stick is flipped, the move will switch out into a wall jump.
+
Mario Tornado
Mario spins around rapidly, sucking enemies in and sending them up with the final hit. This move is great for racking up damage. Rapidly pressing during the tornado will cause Mario to gain air, however, this action requires very fast reflexes, and has a lot of recovery time.
() +
Cape
Mario swings his cape in front of him. During the majority of the move, projectiles that hit him will instead be reflected. If an enemy is hit with the sheet, they will reverse direction; Good for ledge-guarding against many different + moves. It will add power to whatever projectile it reflects, and as a result, can actually be broken like a shield if it tries to reflect something that has already been reflected too much. If this is used mid-air, Mario will gain some air, aiding recovery.
He throws the opponent on the ground, who then bounces up. It can chaingrab characters with moderate falling speeds like Pikachu from moderate damages, and chaingrab fastfallers like Link at higher damages.
Forward
Mario swings around once and throws the enemy forward. Decent knockback.
Mario simply throws the enemy up. Can combo into an up tilt or starting combos. It can be used to chain grab fastfallers.
Back
Mario swings around several times, throwing the enemy behind him powerfully. This can be used to KO opponents at low percentages. It is the fourth strongest back throw in Melee. It resembles how he threw Bowser in Super Mario 64.
