Whack is a move that has a chance to one-hit-KO (which increases along with the hit enemy's damage), similarly to Thwack, but even less likely to insta-kill at lower percentages. It also does little additional damage or knockback. However, this loss in damage, potential to hit multiple enemies and reliability is compensated by the fact that this move has more range. Instead of instantly affecting an area, this move will shoot a medium-sized, slow and medium-ranged black orb that waves up and down slightly in midair and causes its effect upon hitting a target. Its execution is also faster as it doesn't have startup delay like Thwack does. Whack will not appear if Thwack does.
