A revised edition of Hiryuu no Ken: Twin (known as Flying Dragon internationally), titled SD Hiryuu no Ken Densetsu (SD Legend of the Fist of the Flying Dragon), was launched exclusively in Japan. The update introduced additional characters—such as Jack, Ryu, and Gofire from the Super Chinese series—along with new items and a fresh gameplay mode. It also dropped the more realistic "Virtual Mode" in favor of the exaggeratedly cute "Quest Mode." Playable characters include Ryuhi, Hayato, Min Min, Wiler, Shouryu, Yuka, Suzaku, Powers, Robo No Hana, Bokuchin (unlockable), Jack, Ryu, Raima, E. Quaker, Ellie, Gofire, and Ryumaou (unlockable).
