It greatly pleases me to announce that upcoming team up movie, Kamen Rider x Kamen Rider Wizard & Fourze: Movie War Ultimatum will feature the 4 main previous Rider from the new Heisei era, Kamen Rider Double, Accel, OOO and Birth!
e-plus broke the news earlier today about this dream team up. The article goes on to give more details about the films plot:
The three Akumaizer demons have been revived after thousands of years. Using magic, Zatan, Eel and Gaara revive previous monsters from the Underworld. The Akumaizer are planning to take over the human world, but in order to stop them, Wizard, Fourze, Meteor and Nadeshiko join forces. Eventually OOO, Birth, W and Accel join the fight in the 8 Riders VS The Great Monster Army.
The article does not confirm if the actors are returning or if the heroes will return in suit only. More news when we have it.
