Piranha Plant is the first character and Super Smash Bros Ultimate to be available through downloadable content. It will not be available once Ultimate releases Dec. 7, but it will be available sometime after that for players who take the right steps towards unlocking it.
Get Piranha Plant in Smash Ultimate
For a limited time, players can get the Piranha Plant for free by purchasing a copy of Super Smash Bros Ultimate and registering the game with a My Nintendo account by Jan. 31. If players do that, Piranha Plant will join the game as soon as it's available.
If players don't do the method listed above, Piranha Plant will still be available, but it will not be free. It will be the first DLC character and smash ultimate, and purchasable for an yet to be determined price.
