The Tomodachi universe (トモダチコレクション, Tomodachi Collection) refers to the Super Smash Bros. series' collection of properties that hail from Tomodachi Collection and Tomodachi Life (known in Japan as Tomodachi Collection: New Life) for Nintendo DS and Nintendo 3DS respectively. This handheld exclusive series has players feed, clothe, and 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 Tomodachi universe was the first universe from Nintendo brought to iOS and Android (mobile devices) with (the now discontinued) Miitomo.

In Super Smash Bros. for Nintendo 3DS[edit]

The series is represented by a single stage, its music track, and two trophies in Super Smash Bros. for Nintendo 3DS.

Stage[edit]

• Tomodachi Life (Starter): 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, the player will encounter a Mii character in the apartment pulled straight from their 3DS's Mii Plaza.

Music[edit]

• Tomodachi Life - An arrangement of the daytime theme from Tomodachi Life and the daytime theme from Tomodachi Collection, which plays on the Tomodachi Life stage.

Trivia[edit]

• The series symbol for the Tomodachi universe seems to be loosely based on the house a couple owns after marriage, albeit with a slightly altered window.
• The R.O.B. treasure's description in Tomodachi Life references his playability in Super Smash Bros. Brawl.
