Hitbox visualization showing Bowser's up special, Whirling Fortress, when aerial.

Overview

Bowser’s up special is Whirling Fortress. He withdraws into his shell and spins around rapidly. It starts up on frame 6 and is capable of moving forward or backward while doing so, which makes it an extremely effective out of shield option, launching opponents vertically and easily putting them into a disadvantage. In the air, it propels Bowser diagonally upwards, travelling below average distance vertically above average distance horizontally. The move can cover a greater distance via button mashing near the end of the move.
