Piranha Plant (SSBU)/Up special

Hitbox visualization showing Piranha Plant's up special, Piranhacopter.

Overview

Piranha Plant rotates its leaves around itself like a helicopter, taking flight. It can recover from the bottom of the blastzone and reach the ledge of any legal stage, assuming no movement left or right is used, which makes it travel less vertical distance. It is fairly easy to move around with it, and the hitboxes last long, making it a fairly good recovery move. Its main weakness when recovering however is that the hitboxes only cover Piranha Plant's leaves; its head is completely exposed otherwise, making it very exploitable, thus requiring Piranha Plant to mix up movement. It is possible to alter Piranhacopter's movement via flying against walls, decreasing its speed depending on how much it is tilted. Piranhacopter also has very low landing lag from special fall, and combined with Piranha Plant's fast fall speed, makes high recoveries a good mixup when low recoveries constantly get punished.

As an attack, Piranhacopter can do lots of damage when it fully connects, and even work as a kamikaze move offstage, dragging opponents to the blastzone. However, it has 2 fatal flaws; the first being its very low knockback overall, making it very unsafe on hit if Piranha Plant doesn't land onstage in time, and the second is the multihits incredibly high SDI multipliers, at 3x for the regular multihits, and 3.5x for the last multihits. This makes the move effectively useless as a conventional attack, as there are enough hits to be able to SDI out easily. However, when recovering, it can be difficult to tech this move, making stage spikes rather easy, especially with the launch angle it has on the final hit. If the multihits don't connect properly, they can also pseudo-spike.
