The Tomodachi universe refers to the Super Smash Bros. series' collection of properties that hail from the handheld exclusive Tomodachi Life and Tomodachi Collection series for Nintendo DS and Nintendo 3DS where players watch over the more-than-often ridiculous lives of their Mii characters, as they go about and perform daily activities, make friendships, and start romantic relationships (to the point of marriage and starting a family).
The series is represented by a stage, its music track, and two trophies in Super Smash Bros. for Nintendo 3DS.
- Tomodachi Life: A stage set in the Mii Apartments. The front walls of the apartments disappear so the area within is visible when a fighter overlaps with the room. The rooms are randomly placed and selected from among several types. Occasionally, you will encounter a Mii character in the apartment pulled straight from your 3DS.
