Dragon Ball Z: The World's Strongest
In his lab, biotech specialist Dr. Kochin collects the dragon balls to free his master, Dr. Uirou-a deranged scientist obsessed with world domination-who remains trapped in the eternal ice of the Tsurumai-Tsuburi Mountains. While searching for the dragon balls, Gohan and Oolong arrive at the site, only to be ambushed by strange creatures called "Bio-Men." Piccolo, training nearby, tries to rescue them but is interrupted by three unknown fighters. The ice suddenly cracks beneath them, halting the fight and burying Gohan and Oolong in the collapse. After waking up, Gohan and Oolong return to Kame House, where Bio-Men confront them, demanding that Muten-Roushi come with them. He refuses and effortlessly defeats them, catching Dr. Kochin's attention. Believing Muten-Roushi is the world's strongest man, Kochin kidnaps Bulma to force Roushi's cooperation in his cryptic scheme involving his master. Who are Dr. Kochin and Dr. Uirou? And what is their true goal?
