Mii

Miis are digital avatars created specifically for Nintendo platforms. They were introduced with the Wii in 2006 as general avatars but became more prominent in 2011 with the release of the Nintendo 3DS. Like other Nintendo Network services, Miis are used to represent users in Miiverse since its launch in 2012. Miis can be created in Mii Maker or transferred from the Wii Mii Channel or other Nintendo systems with Mii Maker. In Miiverse, you can choose a normal face, happy face, winking face, shocked face, angry face or sad face to attach to your posts. Your Miis will mimic that face for each post.
