Gohan's Plight! The Preposterous Great Saiyaman Film Adaptation?!

S4 E27: Mr. Satan reveals to Videl and Gohan that he is starring in a new superhero movie: "Great Saiyaman vs. Mister Satan"! As Videl, Gohan, and Pan check out the film set, the lead in the film - a famous but self-absorbed actor named Barry Kahn - becomes enamored with Videl and tries to woo her. Videl rejects Barry in front of the entire film crew, which angers him. Seeking revenge on Videl for his humiliation, Barry convinces Gohan to take over as the main stuntman for the film in order to embarrass and potentially maim him. As Gohan is the real Great Saiyaman, he uses his powers to easily take on the role. Gohan later dons the suit again for a fight against a pair of bank robbers. When the film crew accuses Gohan of using the suit and stopping the bank robbery, Bulma bails him out. However, Gohan's identity is accidentally revealed to Cocoa, who is a starlet in the movie. Cocoa blackmails Gohan into flying her around the city. Jaco chases after Watagashi (綿餓死) and returns to Earth to arrest it. He suspects "The Great Saiyaman" might be the host of Watagashi (綿餓死), who is an extraterrestrial parasitic criminal that possesses its hosts. Jaco attacks with a massive cannon capable of vaporizing a planet.
