What do amiibo do?

amiibo are interactive figures and cards that can give you access to extra content or other features in compatible software. The effects vary depending on each compatible game: in The Legend of Zelda: Breath of the Wild, you can use the Wolf Link amiibo to summon that character to join you as an ally, while in Super Smash Bros. for Nintendo 3DS and Wii U it's possible to train a fighter to spar against or alongside.
