Hanuman and the Five Kamen Riders

With an unquenchable thirst for the blood of virgin women, the wicked King Dark enslaves the brilliant Thai scientist Dr. Wisut to create an army of monsters to put an end to the chivalrous efforts of the cyborg warrior Kamen Riders. When their efforts fail, can the Hindu god Hanuman help? Semi-official Thai/Japan co-production between Chaiyo and Toei. Toei allowed the usage of the Five Riders vs. King Dark film while Chaiyo forgot to license the characters out (Source: Dubbing Wiki).
