Now that Piranha Plant is in players' hands and the community has had a chance to get a feel for the character, we're starting to see more and more content focused on the character. As with Super Smash Bros. Ultimate's previous newcomers, Delzethin has put together a breakdown of Piranha Plant's moveset. While not an in depth guide, it does provide a decent overview of the character's design and overall playstyle.
Generally there seems to be a trend towards verticality with Piranha Plant's moveset, with decent burst speed but average to sub par sustained movement on the ground, strong anti-air options, and somewhat slow aerials that seem more suited to finishing combos than ending them. The character still has some strong options for controlling space on the ground, from a down-smash that hits surprisingly hard to a side special that's useful for covering approaches.
