1: The Arrival of Raditz In this episode, Raditz, Goku's evil brother, arrives on Earth. Goku brings Gohan to a reunion on Roshi's (Kamesenin in the Japanese version) island. After a brush with Piccolo, Raditz finds Goku on the island and offers Goku a place with the Saiyans. When Goku refuses, Raditz beats him up and abducts Gohan 2: The World's Strongest Team After Goku was beaten up in the last episode, Piccolo arrives on Kamesenin's island as well, and tells Goku that they should fight together to defeat Raditz. Goku agrees, and they use the Dragon Radar to home in on the Dragonball on Gohan's hat. The fight began, and Raditz shot two beams at the two, missing Goku, and blowing off Piccolo's left arm. Goku was then beaten to the ground, and the episode ends. 3: Gohan's Hidden Powers In the beginning of this episode, Goku and Piccolo regrouped from being thrashed by Raditz, and discussed their strategy. Piccolo unveils his "Beam Cannon Fire" technique (makankosapo in the Japanese version) on Raditz, but misses, and only grazes his shoulder with it. Goku grabs Raditz's tail while he's distracted, an Piccolo prepares his attack once again. However, Raditz talks Goku into letting him go, and Raditz turns on him the moment he does. Raditz steps on Goku a few times, and Gohan, hearing his father's screams, busts out of Raditz's pod, where he was imprisoned. Gohan preforms an all-out head butt on Raditz, and Goku gets up and grabs Raditz in a lock. Piccolo prepeares his Beam Cannon again, and the episode ends. 4: Goku's Unusual Journey This episode starts up with Piccolo shooting through Raditz and Goku with his Beam Cannon, and both of them collapse. Raditz tells Piccolo before he dies that his scouter (the thing over his eye) also acts as a transmitter to the other Saiyans, and that they overheard Piccolo's talking about the Dragonballs. Sure enough, Nappa and Vegeta, the other two remaining Saiyans, overhear this and decide to head for Earth. (What planet were they on? Was it Namek?) Meanwhile, Goku dies and is led to the place where souls go when they die by Kami(-sama) and is told to go across the Snake Way where he will train. Back on Earth, Piccolo regenerates his arm, and takes Gohan with him when he leaves, so he can train Gohan for the fight with Nappa and Vegeta. 5: Gohan's Metamorphosis Piccolo has taken Gohan to an isolated area to train. Piccolo leaves Gohan there for survial training, but he stays close by to watch over him. Kulilin is unable to tell Chichi or the Ox-King where Gohan and Goku are, and sneaks away to Kamesenin's island again. Bulma gets Raditz's scouter to display numbers in our language, and finds out that Kamesenin has less fighting power than Kulilin. Yajirobe knocks on the door, and asks them to come train, and tells them not to revive Goku until the year is up, so he can train in the afterlife. Back with Gohan, he's stuck on the top of a mountain. He sees the full moon and turns into a giant ape, like all Saiyans do. He starts to shoot everything around him, until Piccolo destroys the moon. When this happens, Gohan reverts, and Piccolo yanks off his tail so that this wouldn't happen any more. He gives Gohan a fighting suit and a sword, and flies off to train on his own. 6: Gohan Makes a Friend Gohan wakes up to find that he has new clothes given to him by Piccolo, and no tail. Animals constantly try to eat him, and Gohan seeks refuge in a cave. When he wakes up the next morning, Gohan discovers that the cave was home to a wounded dinosaur. Gohan tends to it, but just before it was totally healthy, the same Tyrannosaurus Rex attacks Gohan again, and the friendly dino is killed. Goku, up on Snake Way, is still running, and finds a street washer. He hops aboard, allowing him time to sleep on the back while he can travel a distance. 7: Trouble on Arlia Vegeta and Nappa are travelling through space when Vegeta decides to stop and "strecth his legs" on the planet Arlia. When the two evil Saiyans land, they are taken as prisoners, and forced to fight for their lives for the entertainment of the Arlian royal court. When Nappa blows up all the members of the royal guard, a large monster is released for them to fight. Nappa destroys this monster easily. Just when all the prisoners thought they were finally free, Vegeta and Nappa depart, and Vegeta takes a shot at the planet, utterly destroying it.
