Spirits (スピリット, Spirit) are a type of power-up and collectible in Super Smash Bros. Ultimate. They are featured prominently in Adventure Mode: World of Light, which depicts them as characters from various video game series who lost their bodies in Galeem's attack and were reduced to disembodied souls.
Spirits effectively replace trophies from earlier Smash installments as the game's main collectible. Gameplay-wise, most spirits can be equipped to fighters to enhance their stats and/or provide positive effects. Thus, they are also similar to stickers in Super Smash Bros. Brawl and equipment in Super Smash Bros. 4.
A total of 1528 spirits can be obtained in game, all sorted into 42 series.
