Ryuhi (龍飛 ryu "dragon" hi "flying") stars as the main character of the Flying Dragon fighting/RPG series from Culture Brain. The series was named Hiryu no Ken, "Fist of the Flying Dragon", in Japan. Ryuhi's name is written with the same characters as the word "Hiryu" - he is the eponymous flying dragon.
In the games, Ryuhi was born and raised in the mountains of China by the kung-fu master Gen Lao-Tsu. He has the hidden ability to transform into a "dragon warrior" (no relation to the Enix series) which gives him magical armour, swords, and special attacks.
In Flying Warriors, a North America only release based on parts of Hiryu no Ken II and III, Ryuhi was redesigned and named Rick Stalker to appeal to Western audiences by Culture Brain USA. The Westernized version of the dragon warrior was to transform into one of the "Flying Warriors", superheroes in tights.
