Després de cinc tranquils anys pare i fill es dirigeixen a Kame House per a una celebració però aquesta és interrompuda per un misteriós guerrer alienígena.

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 fleetfooted 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 ZFighters 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 ZFighters 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 ZFighters 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 into 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!

Vegeta has been defeated, but there’s no time to celebrate. The Z-Fighters must find a way to resurrect the friends who died stopping the Saiyan invasion. Fortunately for the fallen, Krillin has a plan!

Preparations for the journey to Namek hit a snag when Bulma accidentally blows up the remaining Saiyan spaceship. Mr. Popo may know of another vessel, so he and Bulma travel to the Earth’s end for a closer look.

A bad case of space boredom makes Bulma a pain to share close quarters with, and Vegeta recovers from his injuries only to discover that Frieza has a head start on tracking down the magic Dragon Balls!

Gohan and Krillin beat up on Frieza’s henchmen, but their spaceship is destroyed in the process. Vegeta is headed for a showdown with Cui, and the shrewd Saiyan is keeping his true power level under wraps!

Goku blasts off in a brand new spaceship specially equipped with a device designed to help increase his strength! On Namek, Krillin and Gohan watch in horror as Frieza’s men slaughter innocent Namekians.

Gohan and Krillin risk their lives to rescue a young Namekian, and Vegeta goes on the rampage after learning the truth about the destruction of his home planet!

After easily defeating Dodoria, Vegeta begins his violent search for the two remaining Dragon Balls. Meanwhile, Krillin and his new friend Dende set out to warn the eldest Namekian of the horror headed his way!

King Kai telepathically “phones” Goku with a warning to stay as far away from Frieza as possible! Back on Namek, Vegeta is shocked to discover how much a simple transformation can increase Zarbon’s power.

The eldest Namekian unlocks the full force of Krillin’s dormant power, so the bald brawler can better protect his Dragon Ball. Elsewhere, a Saiyan-related premonition prompts Frieza to call for reinforcements.

Vegeta lays it on the line in a daring attempt to steal the Dragon Balls right out from under Frieza’s nose. Krillin’s riding high on a Namekian power surge, but he’s about to wander into a dogfight he can’t survive!
