After the Three Fist Demons were disposed off and Rio solidified himself as master of the Rinjuken Akugata, Long presented himself to Rio and offered him a chance to master the Genjuken style. Rio accepted and Long conducted the Blood-Oath Ceremony to grant both him and Mele new Genjuken forms. However, Long secretly intended to use Rio as his candidate to embark on the Infinity Path and become a "Destroyer" who would reduce the world to ruin.
Eventually, Long would succeed in molding Rio into his destroyer after Rio was defeated by GekiRed and his anger over losing caused him to awaken as the Destroyer. However, Rio was deconverted from his transformation by his own right-hand Mele and his love for her. With Rio no longer the Destroyer, Long attempted to finish off the Gekirangers and Rio so he could find a new candidate to be his Destroyer, but was destroyed by the Gekirangers.
