Geno Whirl

Geno Whirl is an attack Geno learns at level 11 in Super Mario RPG: Legend of the Seven Stars. It is a disk attack that follows a straight path to and through the enemy. Geno Whirl is notable for being one of the most powerful attacks in the game; if timed correctly it will deal 9999 damage, but this doesn't apply to bosses (except for Exor and Yaridovich clones). The correct timing is when the whirl leaves the screen. The attack has to be precise otherwise it will miss.'
