Whirling Fortress

Whirling Fortress is Bowser's up special move in Super Smash Flash 2. Bowser pulls himself inside his shell and quickly spins around. If an opponent is hit within the beginning of the attack, they will suffer more knockback. In addition to being a powerful attack, in the air, it gives Bowser great horizontal recovery and some vertical recovery, similar to Donkey Kong's Spinning Kong.On the ground, bowser spins while moving horizontally.
