Won Hyo is one of the antagonist of Shin Angyo Onshi and was a high-ranking sorcerer from Jushin, and a former ally and friend of Munsu. She is portrayed as a hermaphrodite in the Korean, Japanese and Vietnamese versions, while in the English manga, Won Hyo is male. Despite her demon heritage, she ultimately rejected her race's bestiality and mindless massacre of humans, choosing to side with Jushin during the war against the Kaidaten. Over time, she came to despise her hideous demon body, preferring to assume human form through her magic. Along with Won Sul, she switched allegiances to Aji Tae following Jushin's fall, helping him grow the narcotic Yang Gwi Bi plants.
