Bowser (SSBU)/Up special
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.
