Kamen Rider x Super Sentai x Metal Hero: Superhero Taisen XD!

This is the fourth installment of the Superhero Taisen movie series. And, for the first time ever: ALL Metal Heroes will join in, other than the Space Sheriffs!

SYPNOSIS:
Hatching a plan to defeat their respective enemies and get rid of the Space Sheriffs, the Spitemax Empire and the Mutnoms decide to split up and team up with other villain organizations and kidnap two teams named Kabutack and Robotack. The Mutnoms form an alliance with the Black Cross Army, and to abduct Kabutack and frame Kamen Riders Sirven and Gunner for the crime. Also, the Spitemax Empire have formed an alliance with Jamahl, and to capture Robotack and have the Royangers framed for this incident. Then, the Space Sheriffs witness those two following incidents on the screen: the B-Crushers from Jamahl, disguised as the Royangers, capture Robotack, and Dr. Hinelar and Gaija from the Black Cross Army, capture Kabutack while disguised as Sirven and Gunner. Sirven and Gunner then rush in and battle the unsuspecting Royangers, so they can arrest them, thinking that they are responsible for the Robotack's kidnapping. But, the Royangers and the Riders were all arrested by the Space Sheriffs for the Kabutack/Robotack incident. When the two teams were jailed, little do they know that the Space Sheriffs were tricked by villains in disguise, and they are transported into a deep space forcefield. Discovering taht the Kabutack/Robotack is a diversion to get rid of all heroes, the Royangers and the Riders put aside their differences and escape. Will they defeat the four villain teams, rescue Kabutack and Robotack, free the Space Sheriffs, and clear their names?
