リアルバウト餓狼伝説
is one of the five playable characters introduced in "Fatal Fury 2". An elderly judo master who was once known as "Yamada, the Demon" during his youth. Jubei Yamada is the best friend and rival of Hanzo Shiranui (the grandfather of Mai Shiranui). Having lost his charm from his younger days, Jubei fights in the new King of Fighters tournament in order to re-establish his popularity with girls around the world. Despite this, he refuses to change his womanizing lecherous ways. Although Jubei does not return as a playable character in later games, he makes several cameo appearances, including in Mai Shiranui's ending in "Real Bout Fatal Fury", where he is shown to have an infatuation with her.
