The invasion has begun! A youthful Piccolo Daimao sets out to vanquish the world, sector by sector, and he's starting out with the peaceful inhabitants of the King's realm! Meanwhile, Goku hopes to regain his strength by visiting Karin Tower, if he can climb it, exhausted and frail.

Goku's reunion with Karin is filled with hope and disappointment as the hero receives shocking news! Meanwhile Piccolo Daimao attempts to force the King's obedience through a horrific display of brutality towards his kingdom and subjects as Tenshinhan prepares for the long journey to learn the secret of the Mafuba.

Something stirs in the cold, deep black below. Moans bellow from a hallow cavern beneath the ice. The Dark is alive! And it calls for Goku, as he sets out on a dangerous quest to find the Super Spirit Water. One sip could mean amazing power - or painful death!

Goku and Yajirobe seek the Super Spirit Water, a mystical beverage that will grant either great power or death. But surprise follows surprise as Goku finally finds Darkness, the keeper of the Super Spirit Water. After Goku proves himself worthy, Darkness allows him to drink the perilous potion. But will he be empowered or perished?

Tenshinhan masters the Mafuba, deciding to use it against the evil Piccolo Daimao. One problem: if used against an opponent the Mafuba will kill its user! Meanwhile Goku and Yajirobe return to Karin Tower where Goku discovers his new powers and is given another Kinto'un. Can Goku reach Piccolo Daimao before Tenshinhan sacrifices himself?

Piccolo Daimao has declared annihilation of the world, one sector at a time. First up, Metro West, home of Bulma's parents. Tenshinhan, having mastered the Mafuba, prepares to fight Piccolo Daimao, but a new menace threatens all. Goku race to offer aid, but will it be too late?

There's a new beast in town and his name is Drum. Tenshinhan must go through him before he can fight Piccolo Daimao. The problem is, Drum moves faster than Tenshinhan's eyes - all three of them! Goku is on his way, but will he arrive in time to save the day?

Goku is back to face Piccolo Daimao, and not a moment too soon! As Tenshinhan and the rest of the resistance endure their most desperate hour, only Goku stands between Piccolo Daimao and the destruction of Metro West. It's more than just a rematch, it's the battle to save the world!

Piccolo Daimao puts all of Metro West on edge when he invades the King's Castle, but Goku is not about to let him take over without a fight. While Tenshinhan watches from the sidelines, the young warrior takes it on the chin and refuses to go down. It's a fierce battle but even Goku has his limits. How much can he take?

The fierce battle between Goku and Piccolo Daimao continues, but Piccolo gains the advantage when he breaks Goku down limb by limb. To make matters worse, Tenshinhan is used as a pawn in the battle. Goku is forced to make an awful choice. Will he surrender to Piccolo Daimao and save his friend or choose to fight and risk his own life?
