Super Smash Bros. Ultimate/Spirits

In previous games from the Super smash Bros. Series, you used to collect trophies, and in Super Smash Bros. brawl, you also collected stickers. In Super Smash Bros. Ultimate, they replaced Trophies for another collectable, called "Spirits". It's like a better version of the stickers from brawl. Spirits are characters and things from various game series (represented by Artworks or renders) that makes your fighter stronger by increasing your Power and defense, and also giving a bonus ability or item.
