Sneak Brother Younger was part of an army of resurrected (mostly Super Sentai) monsters led by Space Raider after the revival of Madou Demon King Psycho. They proceeded to attack the gathering of Kamen Riders and Super Sentai, giving them a hard time. Younger helped beat Kamen Rider OOO with Rhino Doubler, Ayakashi Chinomanako and Action Commander Stargull. The heroes of recent years were in a pinch until the arrival of a force of Sentai and Rider reinforcements led by Akarenger and Kamen Rider Ichigo. The combined forces of superheroes were able to turn the tide against the Madou army, with Younger being beaten back by OOO. They lined up and used their various finisher attacks to destroy the revived monsters.
