Ouyang Feng is a fictional character in the wuxia novel The Legend of the Condor Heroes and its sequel, The Return of the Condor Heroes, by Jin Yong. As the Western Venom (西毒) of the Five Greats (五绝), the top five champions of the first martial arts contest on Mount Hua, Ouyang Feng is best known for his signature martial arts technique, the 'Toad Skill' (蛤蟆功), and his expertise in toxicology. In the first novel, he is depicted as a ruthless villain who resorts to all sorts of unscrupulous means to achieve his goal of becoming the most powerful martial artist in the jianghu. He attempts to seize the Nine Yin Manual, a book detailing powerful martial arts and inner energy techniques, but is tricked into practising skills based on a corrupted version of the manual. He becomes insane eventually as a consequence, but his prowess in martial arts also increases tremendously in an unorthodox manner. In the sequel, Ouyang Feng has become insane, however, he learns to be kind to others, for example, letting Yang Guo call him Father, and passed some of his martial arts to him. Later in the novel, he dies in the midst of laughter and forgotten past feuds alongside his rival, Hong Qigong. He is buried on Mount Hua beside Hong Qigong by his godson, Yang Guo, who succeeds him as the Western Eccentric of the new generation of the Five Greats.
