Cooler's Revenge

Cooler watches as his younger brother Frieza destroys the Saiyan home world. His henchmen prepare to destroy a space pod fleeing the doomed planet that is transporting a Saiyan infant to Earth; but Cooler allows it to go, accounting that it is Frieza's responsibility. More than twenty years later, this Saiyan, Goku, defeats Frieza. After learning of his brother's death, Cooler takes his men – Salza, Neiz, and Dore, on a mission to reclaim his family's honor. On Earth, Cooler's forces ambush Goku and his friends while they are on a camping trip. Goku is badly wounded when he protects Gohan from an energy blast launched by Cooler.
