Mario is an all-around fighter who uses his wide variety of techniques to respond to any situation. In Super Smash Bros. Ultimate, he shows up in his wedding tux and builder outfit, and Cappy even makes an appearance!
Excellent combo game, with a versatile amount of tools to combo and juggle opponents

Moveset allows him to adapt well to most situations
Possesses a wall jump
Has a sex kick neutral aerial that is good at starting combos as well as interrupting enemy combos
Good at edge-guarding
Possesses a meteor smash: forward aerial
Fireball is a decent projectile that can be used for zoning, approaches, gimping, and edge-guarding
Cape is a reflector and also forces enemies to change directions, allowing it to frustrate recoveries
Cape also stalls his aerial momentum, assisting in recovery
FLUDD disrupts recovering opponents easily
Poor range on many attacks
Underwhelming recovery distance
Has difficulty approaching without the use of Fireballs, which cannot be easily spammed
Relies very heavily on combos to deal significant damage
