Rhythm Fighter

Rhythm Fighter (Japanese: リズムファイターVS Rizumufaitā VS) is the 4th Rhythm Toy in Rhythm Heaven Fever.  It is unlocked with 21 Medals. It is the only rhythm toy that supports and requires two players.

Gameplay
Rhythm Fighter features two doll-like figures standing in an arena fighting, similar to the Muscle Doll from Figure Fighter. Like the two player Rhythm Games, the first played is on the left with an orange color scheme, while the second player is on the right with a blue color scheme. On the top of the screen, there's a green health bar for both players.

This competitive game is divided into numerous rounds. During each round, a rhythm of beats flashes on the screen. One player, the attacker, creates an attack rhythm of punches and kicks using the beats. The other player, the defender, must then repeat the same rhythm to dodge the attacks. If the defender dodges at the wrong time, he will be briefly stunned and any attacks during this time will automatically succeed. Successful attacks deplete the defender's life bar and when a player is hit 13 times, he is KO'd and loses the game. The roles of attacker and defender switch between players often, and the speed and rhythm change with every new round.

Trivia

 * The music from Rhythm Fighter is reused for the Figure Fighter VS game in Rhythm Heaven Megamix.
 * This Rhythm Toy, along with Octopus Machine, is set up like a Rhythm Game.
 * The repetitive nature of the game, fail condition, and lack of a proper end make it similar to an Endless Game, although there is no score to be kept.
