Genjuken (幻獣拳, Genjūken, "Mythical Beast-Fist") is a group of martial artists which succeeded the Rinjuken Akugata. Utilizing a golden qi called Genki (幻気（げんき）, "Mythical Qi"), Genjuken users seek to surpass the power of natural beasts by mastering the power of mythical beasts, with thirteen fighting styles based on the Five Sacred Beasts and the Chinese Zodiac. Overtime, the Genjuken style is revealed to be a front for Long to raise a potential human though the Infinite Path (無限道, Mugendō), turning that person into a mindless monster that would destroy the world.

But Gou is not easily fooled and saves his brother from being trapped in the Mirror World. Shiyuu is wounded by GekiBatTohja Wolf before SaiDaiOh lands the deathblow.

Because of his mischievous personality, there are sometimes in which Shuen himself doesn't distinguish between himself and his clones. He was sent to cause mayhem with his clone Gengi on Christmas Eve to gather screams until the Gekirangers' interference caused him to withdraw via arson and encounter Ken Hisatsu, who took the Phantom's attempt to ruin the holidays personal and defeated him.
