Dragon Ball Super: Super Hero

Years after his defeat by a young Goku, Magenta seeks revenge against Goku's family and allies. He revives the Red Ribbon Army and hires Dr. Hedo, grandson of the evil scientist Dr. Gero, to create powerful androids. Hedo, believing Earth's heroes are alien villains, develops Gamma 1-gou and Gamma 2-gou. While Goku and Vegeta train elsewhere, Piccolo mentors Pan, Goku's granddaughter, as he once trained Gohan, Pan's father. Gohan, now a scholar, must return to his warrior roots when the Gamma androids threaten Earth. The Gamma androids believe they fight for justice, but a sinister plan is brewing at the Red Ribbon headquarters. Gohan and Piccolo must protect Pan and defend the planet from the new robotic threat.
