Zelda (SSBU)/Up special

Overview
Zelda twirls to whip up a green tornado around herself before vanishing and reappearing, using the tornado to attack. The move is a solid recovery tool, with good directional control and reach, however, the move doubles as a solid kill move due to it's predictable launch angle on the starting hit, allowing Zelda to aim her reappearance upward to line up with the opponents trajectory, killing at low percents towards the top of Final Destination.
