Bowser (SSBM)/Back roll

Hurtbox visualization showing Bowser's spot dodge.

Overview

Bowser retreats into his shell, becoming fully intangible, before spinning along the ground backwards in a manner similar to the animation of his down smash. The move is the worst back roll in all of Melee: while it has the median start-up and number of intangibility frames, it has the 2nd-highest end lag of any back roll (only behind Samus's back roll), and the shortest distance traveled. Even if it did not have such horrible stats, Bowser has a far superior out of shield and escape option in the form of grounded Whirling Fortress, which grants Bowser frame-1 intangibility while also putting out a hitbox, and can even have its end lag cancelled by Fortress hogging. This all leaves Bowser's back roll with no practical use, making it an avoid-at-all-cost move.
