Amiibo

Amiibos are special objects that can be used in Super Smash Bros. for Wii U. The Amiibos are figures that the player can purchased that acts as a customizable character.

Summary
In order to use an Amiibo, the player must place it on the square sensor part of their Wii U gamepad to activate it. However, the player must also have Super Smash Bros. for Wii U in order to make them work. Then, the player is free to name their Amiibo and customize it using special powerups found by either clearing through Classic Mode or by playing Smash Tour. This is a way for the player to customize their own Amiibo to make it stronger and level up (with 50 being the highest level they can reach).

Amiibos
There are Amiibos for all of the main playable characters of Super Smash Bros. for Wii U. However, there isn't any for the Miis playable.
