Jade is the biological son of Brocken Jr., a departure from the original Japanese version where Brocken Jr. served solely as his trainer. This familial connection was established in the English dub of the series.

His identity is deeply rooted in his father's legacy. Brocken Jr., a former antagonist turned Idol Choujin, competed in the 21st Choujin Olympics and later became a vital ally to Kinnikuman. After losing his arm in a match against Ramenman, Brocken Jr. continued wrestling with a prosthetic. Jade inherits this legacy of rivalry and resilience, positioning himself as an early adversary to Mantaro (Kid Muscle), driven by his family's history with the Kinniku clan.

Within the "Ultimate Tag" storyline, Jade allies with Scarface (Mars) and another character, forming a team that emerges as formidable opponents. This alliance highlights Jade's role in the ongoing narrative of intergenerational conflicts and alliances among Choujin wrestlers.
