Mario (SSB)/Down smash
Mario spins around while performing a breakdance kick on the ground, dealing 17% damage and horizontal knockback, with a similar animation to Mario's crouching attack from Super Mario 64. The move is pretty powerful, being capable of KOing most characters at around 110%. Its fairly quick startup makes it a decent way to react OoS, and a decent surprise KO option. It can also be used in a jab cancel. The move's duration makes it a great option for reading rolls, as attempting to roll behind Mario during the front part of the attack will cause the opponent to get hit by the back part of the attack. Additionally, the move is able to edgeguard in certain situations, and is a great way to deal with many edge options, especially at above 100%. Considered Mario's third strongest KO move, behind his up smash and back throw.
