History
Powerless as a child on the night that his entire family were slaughtered by a monster, Rio was taken in by Gekijuken's Kensei Sha-Fu and was motivated to become strong enough to never feel weak again. But Rio's obsession for power consumed him, seeing his senior Dan as a rival while becoming disillusioned with Gekijuken. Rio proceeds to revive the Rinjuken Akugata school to learn its technique, abandoning his friends after Dan was mortally wounded by someone before their fight could conclude. Years later, having revived all of Rinjuuken's long dead practioners to serve him, Rio gains the Bracelet of the founding Kenma and sends his minions to cause as much suffering as they can to increase their Rinki. It when the Gekirangers oppose him that Rio finds his new rival in Jan, the two fighting each other on numerous occasions before learning his entire life was orchestrated by his family's killer.

Ringi
Rinju Lion Fist:
 * Rinki Triumphant Armor: Transformation Ringi
 * Brave-Roar Wave: Generates his Rinki in the form of RinLion that runs at the opponent, mauling them.
 * Brave Strike: Similar to the Brave-Roar Wave, Rio charges at a person with an aura of Rinki around him as he slugs his fist though the opponent's body.
 * Lion's Roar Wave:: A stronger version of the Brave-Roar Wave.
 * Violent Kick Fist: A Physical attack that does not require much Confrontation Ki, but is deadly.
 * Thunder Hard Bullet: Produces an explosive orb of Rinki to fling at his opponent.
 * Brave-Roar Bullet: A stronger variation.
 * Great Charge Roar: Rio's strongest attack, a last resort move where he expels all his Rinki at once in a suicidal attack to destroy his enemy.

Feats
