|This article is about a/an mentor in Juken Sentai Gekiranger.|
Master Sha-Fu (マスター・シャーフー Masutā Shā Fū?) is a grand master of the Fierce Beast Felis-Fist (激獣フェリス拳 Gekijū Ferisuken?) style. He is the mentor of the Gekirangers and leader of the Fist Sages, mastering all three of its aspects and able to channel Extreme Ki.
He seemed to had a relationship with Rageku prior to their transformations, with him spurring her love for him. He was originally a friend of Maku; however, Sha-Fu turned down Brusa's offer to be his successor and suggested Maku. This act of kindness wounded Maku's pride and ended their friendship, which Sha-Fu regretted ever since.
Sha-Fu appears to be an aged anthropomorphic caracal with his eyes normally closed, opening them when he gets serious and deep like sensing the qi like those of the Akugata. He loves to be scratched on the neck, referred to by Jan as "Cat" (猫 Neko?), and always carries around a musical triangle with him, and rings it once when he pulls it out. His motto is "There is training in one's livelihood" (暮らしの中に修行あり Kurashi no naka ni shugyō ari?), as his training has the Gekirangers learning from the various things life has to offer. While helping Jan, Sha-Fu found one of Long's scales in the ruins of Jan's hometown, learning the truth behind Maku's betrayal among the revelations of Rio and Jan's past encounters with Long.
Master Sha-Fu makes a cameo in the Gekiranger tribute episode of Kaizoku Sentai Gokaiger, Niki-Niki! Kenpō Lesson. He asks Jan if there was anymore he could have taught Don Dogoier (Gokai Green) and Ahim de Famille (Gokai Pink). Jan tells him that they'll be fine as they understand that wanting to become stronger is a sign of being stronger already, and then goes off and says he has to train more so he can catch up with them after taking a bewildered Sha-Fu's triangle and rings it once.

When he fought Rio and Mele, he says, "There is training in one's livelihood. The Fierce Beast Fist well achieved on a daily basis. Felis-Fist, Sha-Fu!" (暮らしの中に修行あり。激獣拳とは日々よく生きることと見つけたり。フェリス拳 シャーフー！ Kurashi no naka ni shugyō ari. Geki Jūken to wa hibi yoku ikiru koto to mitsuketari. Ferisuken, Shā Fū!?).
Felis-Fist Gekiwaza Used by Master Sha-Fu and taught to the Gekirangers.
- Double-Double Clone Fist (倍倍分身拳 Bai Bai Bunshin Ken?): This Gekiwaza allows its user, if he/she possess perfect Heart, Technique, and Body (心技体 Shin-Gi-Tai?), to project his or her Fierce Ki in a gigantic form.
- Due to the short Momotaros's Summer Vacation between the Gekiranger movie and Kamen Rider Den-O: I'm Born!, Sha-Fu is the first Sentai character to both appear and interact with actual Kamen Rider characters, in this case being Den-O's Imagin; the first actual Sentai/Rider crossover will not be for two more years.
