The Find Mii universe (すれちがい伝説, StreetPass Legend), known as the StreetPass Quest universe in PAL regions, refers to all characters, stages, and items that hail from StreetPass Mii Plaza's series of two StreetPass-powered RPG-esque games Find Mii and Find Mii II, in which the player controls the Mii characters of players that have been tagged via StreetPass, known as Heroes in-game, to battle monsters in order to save the King or Queen, represented by the Mii of the player, and the identical Prince and Princess in Find Mii II. Mii-like dogs or cats, depending on the player's preference, can also purchased via Play Coins and are known as Wandering Heroes. There is also a concept in Find Mii II called "Hire Old Allies". This allows players to hire higher level heroes of specific colors, which is useful for rooms that require Miis of a specific color to advance. The rewards for the game are hats that the player's Mii can wear in StreetPass Mii Plaza. There are also various potions in the game that aid in the player's quest.
