Bowser (SSBU)/Up smash

Hitbox visualization showing Bowser's up smash.

Overview

Hops to thrust his shell upwards while spinning. Deals the most damage to opponents who come into contact with Bowser's shell spikes, while other opponents get hit by the sourspots on his head and tail or the landing hitbox instead. The sweetspot KOs at around 80% uncharged, making it the strongest up smash in the game. Grants damaged-based armor (frames 11-15) and invincibility on his shell (frames 14-27), making it an excellent anti-air tool that is hard to compete with.
