Episode 1-12
The Arrival of Radditz:
episode 1: Goku learns the truth about his past as a Saiyan from his long-lost brother Radditz. Radditz wants Goku to join with him in destroying Earth's population, but Goku refuses, and so an angry Radditz takes Goku's son, Gohan, as a hostage.
The World's Strongest Team:
episode 2: Goku and Piccolo form a temporal alliance and decide to "take out" Radditz and free Gohan from his clutches. Radditz notices that Gohan is extraordinarily powerful for his age.
Gohan's Hidden Powers:
episode 3: Goku and Piccolo engage Radditz but Radditz proves to be too powerful for them. Gohan, being the Saiyan Goku's son, displays his once untapped powers and blasts through Radditz's spaceship.
Goku's Unusual Journey:
episode 4: Gohan, having burst free from Radditz's ship, charges his uncle and proceeds to beat him until his energy is gone. Radditz recovers and is about to kill Gohan when Goku grabs him and tells Piccolo to blast them both. Both Saiyans are dying (but Goku can be wished back to life), and before his end, Radditz tells that two more Saiyans will be arriving on Earth in a year's time to finish what he started. Goku, now dead, trains on the Serpentine Road and Piccolo takes on the task of training Gohan for the imminent arrival of the two Saiyans.
Gohan's Metamorphosis:
episode 5: Gohan was left alone in a wasteland by Piccolo for survival training. For the first time in his life, Gohan sees a full moon and then transforms into a giant ape. Piccolo is amazed.
Gohan Makes a Friend:
episode 6: Gohan finds an injured dinosaur and tends to its wounds. Unfortunately, a bigger and carnivorous dinosaur attacks and Gohan (though he tries) can't defend. Gohan is knocked out and the sick dinosaur is eaten.
Trouble on Arlia:
episode 7: Gohan's training works! Gohan, in an ironic twist of fate, kills the carnivorous dinosaur he met earlier and devours him. Vegeta and Nappa (the two Saiyans that were supposed to come to Earth) make a change of plan and go to an insect-planet called Arlia. After killing the evil King of the planet and re-uniting the imprisoned Prince with his bride (awww, how kind), Vegeta decides Arlia is worthless and blows it up with a powerful blast (my God!).
Home for Infinite Losers:
episode 8: During Piccolo's self-training exercises, he levitates then accidentally drops a pyramid which causes a gigantic earthquake-type event. Gohan almost gets swallowed by one of the crater's Piccolo's mistake created. Elsewhere, Goku falls asleep on the Serpentine road and falls off. Oh my! That's a LONG fall. Goku falls and falls and falls until he lands in Hell. Using great cunning, he manages to get two of Hell's demons to agree to let him back on the road. Unfortunately for him, the only way back involves Goku having to start from the beginning of the 100 million kilimoter road.
Princess Snake's Hospitality:
episode 9: Goku is charging down the Serpantine road once again when he sees a tower that he hadn't seen before. Once inside this tower, he meets Princess Snake (who tries her best to keep him there). Goku manages to escape (it turns out Princess Snake is an evil reptilian Goddess), and then finds that the tower is not really a tower, but the Goddess's body: a giant fire-breathing snake. Using swift maneuvers, Goku gets the snake to tie itself into a knot and he continues on his way.
Escape from Piccolo:
episode 10: Piccolo clones himself so that he can have someone to fight against (all in the name of training). Meanwhile, Gohan finds out that this training ground he was dumped on was really an island. He makes a raft and sets out for home. Along the way he washes up onto the shores of a village and is helped by a local orphanage. He finds his way just in reach of home, but before he arrives, he changes his mind and turns away. Piccolo sees him and returns him to the island. Here we go again.
Showdown in the Past:
episode 11: Goku's friends (called the "Z Warriors") are desperate to begin their training with the mysterious Kami-sama. Unfortunately Kami-sama doesn't appear to be doing a thing to help them. Bored, the friends stumble upon a strange device that causes a battle simulation. The opponents? Two Saiyan warriors. The outcome? The Z Warriors are slaughtered. The irony? The two warriors in the simulation were only HALF as powerful as the Saiyans that are to come in a few months. The outcome? The Z Warriors must prepare harder.
The End of Snake Highway:
episode 12: Gohan attacks Piccolo in a rampaging frenzy? Why? As it turns out, the spaceship that first brought Goku to the planet is controlling him. Piccolo solves this inconvenience by destroying the ship. Meanwhile, Goku has reached the end of the Serpentine Road!!!
