Kaizoku Sentai Gokaiger vs. Kaizoku Sentai Gokaiger!?: The Savage Villain-World is a fan-made movie that takes place after Tokumei Sentai Go-Buster vs. Gokaiger, serving as a psuedo-sequel. It is based on an on-going fanfiction by Klom99. Rather than mash-up specific teams, the film instead introduces a Super Sentai "Mirror Universe." It also serves as the first unofficially canon appearance of a character from Hikonin Sentai Akibaranger.
