Super Smash Bros. (series)

Super Smash Bros. (大乱闘スマッシュブラザーズ) is a series of crossover fighting games published by Nintendo, featuring characters from franchises established on Nintendo systems. The Rhythm Heaven Series has made minor appearances in these games.

Super Smash Bros. Melee
Super Smash Bros. Melee introduces the character Mr. Game & Watch who later appears in Rhythm Heaven Fever and Rhythm Heaven Megamix.

Super Smash Bros. Brawl
Rhythm Tengoku is listed among the titles in the Chronicle in Dairantou Smash Bros. X.

Super Smash Bros. for Nintendo 3DS
Sneaky Spirits appear as a common enemy in Smash Run in Super Smash Bros. for Nintendo 3DS. They move just like they did in the original game, by popping up and down in the ground, moving toward the player slowly, then jumping back to do it again. The popping can damage a player. Since they hide often and move quickly, hitting them can be difficult. However, they are weak otherwise, and managing to hit them enough sends them flying off, dropping a rare star boost, which ups all the stats of the player's character.

Three trophies based on characters from Rhythm Heaven appear in the "Other" category:

Super Smash Bros. for Wii U
Two songs from the Rhythm Heaven Series are included in Super Smash Bros. for Wii U: Blue Birds from Rhythm Heaven, and Monkey Watch from Rhythm Heaven Fever. These songs are playable on the Miiverse stage.

Additionally, a blank series emblem for a Rhythm Heaven character exists in the data for this game, but goes unused.

Two trophies based on characters from Rhythm Heaven appear in the "Other" category:

Super Smash Bros. Ultimate
The music used in Super Smash Bros. for Wii U returns, along with Fruit Basket, this time playing on the Summit, Hannenbow, Balloon Fight, Living Room, Find Mii, Tomodachi Life, Pictochat 2, Duck Hunt, Wrecking Crew, Pilotwings and Wuhu Island stages, i.e., stages in the "Other" category.

Several characters appear as Spirits. The Rhythm Heaven Series holds the distinction for having the most Spirits out of any non-fighter-represented series.
