Gouyu

Gouyu (ゴウユ Gōyu?): A master of the Gen Jū Cetus-Ken (幻獣ケイトス拳 Gen Jū Keitosuken?) which uses sound-based attacks, thus using small talk while fighting an opponent to effectively use his power. He is the first Gen Jūken opponent the Gekirangers face. He nearly defeats SaiDaiOh, GekiTohjaWolf and GekiFire until GekiElephantFire begins to damage him, although he survives the fight with them thanks to Sanyo's aid, who easily defeats all three opponents. He appears again to fight Gou to protect Rio from him, only to be instantly destroyed in mere seconds by Gou using the Heaven and Earth Disaster Strike. His name is based on Hé Yŭ (合窳) of the Shan Hai Jing, and motif is the Boar of the Earthly Branches.
