Pa-Pa-Pa the Movie: Perman 2003

Directed by Ayumu Watanabe

An origins and highlight film showing how Mitsuo met the alien that gave him the equipment to become a superhero (which for some reason was never explicitly shown in the two main anime, both just start with Mitsuo already having the powers), how he works together with the other Permans, and the rowdy fight with the antagonists.
