amiibo are a line of interactive figurines available for usage with the Wii U and Nintendo 3DS, and both versions of Super Smash Bros. 4 are compatible with them. Every playable character in SSB4 is represented in amiibo form, including characters that are available as downloadable content. Scanning in an amiibo allows players to customize an individual CPU fighter, known as a Figure Player, or FP. amiibo characters can level up over time, becoming stronger and learning their opponents' playstyles in broad strokes. amiibo can also reward their owner with gift items like custom parts and trophies.
