Chop Chop Master Onion (タマネギ先生 Tamanegi Sensei) is a karate instructor with a large green onion for a head in PaRappa the Rapper series. Running the Fruits Dojo, he teaches a group of tamanegi, as well as PaRappa, the ways of karate and how 'It's all in the mind.' In Um Jammer Lammy, he appears in Lammy's dream, in which he tells her that his dojo had been lost (the reason never being specified). However, the dojo remained in his mind, complete with its own casino, which serves as Lammy's inspiration for the game. Also, his song lyrics foreshadow events that would take place later in the game. In PaRappa the Rapper 2, he hosts a show called 'Romantic Karate' in which he teaches viewers karate as a method of expressing love. He is the only teacher to appear in all three games, as well as the only character whose voice actor appears in both the games and anime. In PlayStation All Stars Battle Royale he takes down the MAWLR from the Killzone series in the PaRappa stage : Dojo.
