Superhero Wars was indeed a thing, and it was apparently big enough for a sequel to be in the works. With the appearance of Gavan Type G and the return of the Space Ironmen from the Kamen Rider Fourze movie, the next step in the next super heroic disaster was rather obvious. Joining forces with the sequel's Z, the newest crossover film will be known as Kamen Rider x Super Sentai x Space Sheriff: Superhero Wars Z.
I guess the only good thing from this sequel is that the Metal Hero fans will get to experience some fanservice in the new movie. Hopefully, Superhero Wars Z will be an improvement over Superhero Wars, since the movie has a chance of going with a different premise. If the sequel turns out to be another disaster, I hope that we get a sequel to Superhero Taihen, along with a new concert that unites the singers that were involved with Kamen Rider, Super Sentai, and the Space Sheriff Metal Hero shows.
If you are interested in participating in the movie, Toei is looking for some extras. As for the requirements, you can check out their listing for more information.
