Kamen Riders Eigem, Luster, Jade, and Onok battle the Jewelariats while questoning Kentaro for his evil side, the Youthengers take on the Qado Army, and Yin, Yang, and Jack stop Kevin Irons and his agents from stealing a power core, with Gavan Type-G's help. Then those four hero groups meet, and share their stories. Just then, three villain groups from past Superhero Taisen movies (Space-Shocker from Z, Dai-Makuu from Beta, Black Cross Army from XD) start rising. And the current villain groups form an alliance with those evil organizations in order to find the Hero Eraser, an ancient anti-WooFoo artifact that can wipe the living existence out of the older tokusatsu superheroes that came before the current, once it's activated. Yin, Yang, Jack, Gavan Type-G, and Kamen Riders Ichigo and Nigo hold off Space-Shocker that's attacking their hometown, Kamen Riders Eigem, Luster, Jade, and Onok, and the Himitsu Sentai Goranger take on the Black Cross Army that's attacking Kyoto, and the Youthengers, with the original Gavan helping them, battle Dai-Makuu who is attacking Tokyo. Just then, a familiar face is watching them over the horizon---it's Toei's very-first hero: 7-Color Mask!!! While that, it was a diversion for the Jewelariats and the Qado Army retrieve the Hero Eraser and allow all Kamen Riders, Super Sentai, and Metal Heroes to vanish out of thin air(except Eigem, Luster, Jade, Onok, Youthengers, and Gavan Type-G since they are still current). How will the heroes find the artifact to bring back those teams? Who will help them? Will they be able to defeat Space-Shocker, Black Cross Army, and Dai-Makuu before the entire universe is in their hands?!
