The fourth Madroneck fighter, following King, Fighter and Z, is a notorious legend, having betrayed the fabled Madroneck Force in its earliest days. He was recruited by Madroneck Z, and it was said that they shared the same ethnic background. The four fighters were charged with protecting the fledgling Madroneck Force from the evil tag-team of Genie and his sidekick Blue Killer. When Satin King appeared, backing the evil duo and claiming to be the new Madroneck King, it was Madroneck X who switched sides. He is the only Madroneck wrestler to betray the group. He is an old man now, and spends his days earnestly training young wrestlers.
