Piranha Plant (SSBU)/Dash attack
Piranha Plant lunges forward with a 'dropkick', utilizing its pot/pipe to do so. Dash attack provides great use for Piranha Plant, as it is fast, covers a fair distance, and the high hitbox placement allows it to be used effectively as an anti-air. This makes it a good long-ranged punish tool for when Piranha Plant is not in range to hit with its lower ranged moves, and Ptooie is too slow. It also fares well in tech chases, as it has a second hitbox that hits low enough to hit knocked down opponents (although against certain opponents, it may whiff instead). It is also good at crossing up shields when done correctly, and can typically be safe on shield if crossed up, especially when accounting its extra shield damage and stun multipliers, although opponents with disjoints may be able to punish. While it does lack kill power, it is very good at resetting neutral or setting up an edgeguard. Overall, it is considered one of Piranha Plant's best moves, due to its fast speed, ability to be safe on shield, and its ability to punish when most other moves cannot.
