Miis not made by the player will appear when 1, 2 or 3 players are playing. They are often from Wii Sports, Wii Sports Resort and Wii Sports Club. There are 5 levels of CPU Miis: Beginner, Standard, Advanced, Expert and Master.
The 100 CPU Miis from Wii Sports Resort are equally divided in the 5 difficulty levels. In each level, there are 10 boys and 10 girls.
The 111 CPU Miis from Wii Sports Club are divided in the 5 difficulty levels, with each one having 22 Miis. The only exception is the Beginner level, which has 23 Miis. This time around, the skill levels don't have the same number of boys and girls, since there are more boys (60) than girls (51) in Wii Sports Club.
- In Wii Party, if your are playing a Party Game, the Miis that you are playing with can be switched to CPU if you pause your game and select Autoplay. Only available from 2-4 players.
