9-Volt is an unlockable playable character in this game, being one of Fawful's hypnotized assistants in his goal of hosting the greatest party of all time and establishing his own timewarp kingdom.
He hosts the "Game POWER!" level in this game, where he gives the player some classic Nintendo-themed microgames to play, like he does in other WarioWare games.
