Goku is a legendary warrior and the strongest fighter on the plant, but he's about to encounter a foe from out-of-this-world. What brings this new menace to Earth? And what's up with his tail?
When Raditz abducts Gohan and announces his plans to conquer Earth, Goku and Piccolo are forced into an uneasy alliance. The two rivals don't trust each other, but neither of them can defeat the Saiyan on their own!
Despite the fury of their attacks, Goku and Piccolo are unable to land a death blow in their battle against Raditz. Gohan's unexpected outburst manages to weaken the powerful Saiyan, but it may be too little, too late.
Now that he's dead, Goku must fight to survive in the afterlife, especially during his treacherous trek down Snake Way. Back on Earth, Gohan endures his own punishment as a student in the house of Piccolo!
Piccolo tries to toughen up Gohan with some wilderness survival training, but things get hairy when the young Saiyan sees his first full moon! Meanwhile, Yajirobe summons Earth's strongest fighters to Kami's Lookout.
As the deadly Saiyan invaders approach Earth, Gohan makes slow, but steady, progress under the watchful eye of Piccolo, and Goku struggles with the "gravity" of his training under King Kai.
To prove himself worthy of King Kai's training, Goku must test his mettle against a fleet-footed monkey and a powerful cricket that's big on respect. Meanwhile, in the land of the living, Gohan takes a beating from his monstrous master!
Goku's training under King Kai is finally complete, and he's eager to return to Earth. Master Roshi uses the Dragon Balls to summon Shenron, but will Goku make it back in time to stop the Saiyans?
The Saiyans have arrived, Goku isn't even on the planet, and the overmatched Z-Fighters represent Earth's last line of defense. When Vegeta and Nappa unleash the gruesome Saibamen, Yamcha picks a fight that could be his last!
Krillin's furious attack wipes out the Saibamen, but the Z-Fighters are powerless against the Saiyan warlords. One by one, Earth's defenders suffer devastating injuries or fall in battle. Goku's return is their only hope for survival.
Piccolo hatches a desperate plan to prolong the battle until Goku's arrival. When Vegeta senses an awesome source of power approaching, he orders Nappa to dispose of remaining Z-Fighters starting with Gohan!
Goku arrives in time to save Gohan and Krillin, and the resurrected warrior is eager to put the hurt on Nappa. When it becomes clear that Goku is no ordinary fighter, Prince Vegeta steps in to finish the fight himself!
The stage is set for a final showdown between Vegeta and Goku. The Saiyan Prince is stronger, faster, and far more ruthless. Goku's only hope for victory is a technique that may very well destroy him!
Vegeta can't handle the fury of Goku's triple Kaio-Ken technique, so the Saiyan warlord unleashes his inner ape. Weakened by his furious onslaught, Goku's only hope to defeat the beast is the mighty Spirit Bomb!
As Goku lies exhausted and vulnerable on the field of battle, Gohan and Krillin take aim at Vegeta's only weakness: his tail! If they can take the ape out of the fight, they might have a chance to escape with their lives.
Krillin and Gohan team up to blast Vegeta with a Spirit Bomb, but the Saiyan prince refuses to die. Things look bad for the Z-Fighters until Yajirobe distracts the enemy long enough for Gohan to undergo a transformation of his own!
