A Perfect Pivot is a technique in Super Smash Bros. for Nintendo 3DS and Wii U that mimics Wavedashing. It is achieved by dashing in one direction, then quickly flicking the control stick in the other direction. This will cause the character to slide along the ground in the flicked direction.
As with Wavedashing, characters' Perfect Pivots vary in terms of distance covered. Jigglypuff has the shortest Perfect Pivot, while Captain Falcon has the longest, covering 3 times as much distance.
