- Gaiya (ガイヤ Gaiya )
- Appearing in Ten no Haoh, Gaiya was a master of Kokuzan Ongyō Ken (黒山陰形拳, "Black Mountain Secret Form Fist"), a martial art that allows him to control others and attack people without being seen. Gaiya plots to rule the world from the shadows by dressing in plain clothes to blend into crowds and by secretly pulling the strings of Meioh and his forces.
