Find Mii

Find Mii (known as StreetPass Quest in the British English version) is a stage in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate based on the game of the same name from the built-in Nintendo 3DS application StreetPass Mii Plaza, specifically the top of the ruins of the Castle of Darkness, the game's final level.

The stage has two main platforms; a larger, flat ground on the left, and a smaller, raised piece of ground on the right. There is a large gap between the two, allowing for easy meteor smashes. Additionally, a caged Mii is positioned above the left platform. The Mii is chosen at random from the ones saved on the console. Contrarily, some screenshots show the cage to be empty. The caged Mii has a hitbox and the cage can be destroyed, sending the Mii flying into a background.

The Dark Emperor from Find Mii II can be seen flying around the stage. Occasionally, he gives a single fighter a level boost or hindrance, or he temporarily sinks either of the stage's two platforms. He also occasionally goes into the foreground to attack fighters by coming into contact with them. If a fighter defeats him, they get a temporary stat boost.

The Final Destination variant takes place on a singular platform. The Dark Emperor and the caged Mii are removed.

In Super Smash Bros. Ultimate, the stage's My Music library is now shared with Summit, Duck Hunt, Hanenbow, PictoChat 2, Living Room, Balloon Fight, Tomodachi Life, Wrecking Crew, Pilotwings, and Wuhu Island.
