The in-game characters are taken from the Wii's Mii Channel, which allows the user to create a Mii (a customized avatar) that can be imported into games that support the feature. "Wii Sports" is the first Wii title to use this feature. Miis saved on the Wii will appear in the crowd during bowling games and as members of human-controlled teams in baseball. The non-player characters in the game were also created using the Mii Channel toolset. Miis created on one Wii can be transferred onto the internal memory of a Wii Remote for use on another Wii with different save data.
