Peace has seemingly returned to Earth following Goku’s monumental victory over Frieza, but a new celestial threat soon materializes. A sentient, biomechanical entity known as the Big Gete Star approaches the planet, seizing control of New Namek and draining its life force to fuel its insatiable technological expansion. Dende, the newly appointed guardian of Earth, senses the impending catastrophe and urgently summons Goku and his formidable allies to rescue their beleaguered Namekian friends.Responding to the call, Goku, Gohan, Krillin, Piccolo, Master Roshi, Oolong, and Yajirobe board a spacecraft and travel to New Namek. Upon arrival, they are horrified to find the once-tranquil world overrun by an army of relentless, faceless Cyclopean Guards. Piccolo immediately engages the mechanical hordes, demonstrating his immense power by decimating wave after wave of foes, while Goku confronts
the mastermind orchestrating the invasion: Cooler.To the shock of the Z Fighters, Cooler has miraculously survived his fiery plunge into Earth’s sun. Rescued and resurrected by the Big Gete Star, his battered body has been fused with advanced cybernetics, creating a supreme metallic juggernaut known as Metal Cooler. Driven by an obsessive, burning desire for revenge against Goku and a cold directive to conquer
the universe, Metal Cooler initiates a brutal assault. Goku transforms into a Super Saiyan, engaging his rival in a catastrophic, planet-shaking duel that showcases their staggering capabilities.Despite Goku’s immense power, Metal Cooler proves nearly indestructible. The Big Gete Star continuously repairs his injuries and instantly upgrades his combat programming, allowing him to adapt to every strategy Goku employs. Overwhelmed and battered by the relentless onslaught, Goku falls into a desperate trap when countless duplicates of Metal Cooler emerge from the shadows, easily subduing not only Goku, but also coming to the aid of the other Z Fighters who are swiftly captured and imprisoned aboard the technological behemoth.Drained of their vital energy to power the Big Gete Star, Goku and Vegeta—who arrived to join the fray—find themselves on the brink of death. However, their sheer, unyielding life force creates an overload within the ship's massive power core. Goku and Vegeta channel their remaining fury into a coordinated, explosive double-team assault, shattering the central computer and causing the supposedly invincible Metal Cooler to disintegrate into dust. As the Big Gete Star collapses and crumbles into the vacuum of space, the victorious warriors escape safely, securing a hard-fought and glorious triumph for the universe.
