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.
8: Home for Infinite Losers
Goku, still riding on the back of the street washer, is asleep, and rolls off of the vehicle, and off of Snake Way altogether. He lands in the "Home for Infinite Losers", spelled "HFIL" on the shirts of the ogres who live there. (I thought it was creative to turn "HELL" into "HFIL" :) ) To get out, Goku had to defeat the two ogres that ran the place; one with super strength, and one with super speed. When he had done this, he ate some of King Yemma's special fruit that bolstered strength, and left by way of a secret exit. However, it was the ogres who had the last laugh, because the secret exit led Goku back into King Yemma's Palace; in his desk drawer, to be exact. Goku, with raised and renewed energy from the fruit, set out again on Snake way.
9: Princess Snake's Hospitality
Goku catches up to where he was when he originally fell off of Snake Way, and Comes across a large house, thinking it to be Kiou-sama's place. He is literally sucked inside, and finds a beautiful princess there. The princess makes every effort to get Goku to stay there with her, but Goku insists on leaving. Enraged, the princess reveals her true form, a giant snake that Goku is trapped inside of. Goku flies out, and manages to tie up the giant snake. After this brief interlude, he flies back to Snake Way to continue his journey.
10: Escape from Piccolo
Gohan escapes the wilderness only to willingly return to training as Piccolo reminds him of his mission: to save earth.
11: Showdown in the Past
The warriors experience the awesome reality of the overwhelming power of the Saiyans in the virtual reality of the Pendulum Room and renew their vow to train and fight for the future of the earth while Gohan begins his intensive fighting training under Piccolo.
12: The End of Snake Way
Goku finally reaches King Kai and begins a rather unorthodox form of training in the 158 days that are left before the Saiyans arrive while Gohan is continuing his fighting training under Piccolo despite the fact that Gohan almost killed Piccolo during another metamorphosis as a giant ape.
13: A Fight Against Gravity...Catch Bubbles!
Goku conquers gravity and displays amazing speed and thus is about to be trained by King Kai himself in the KAIO-KEN while the rest of the good guys polish up their skills for the showdown against the Saiyans.
14: The Legend of the Saiyans
Goku continues his training under King Kai, as King Kai reveals to Goku his unknown Saiyan heritage.
15: Black Day For the Planet Earth
Goku finishes his training with King Kai. King Kai helps Goku contact Master Roshi through his psychic powers, and Roshi wishes Goku back to our dimension with the Dragon Balls. However, even at the rapid pace Goku travels through Snake Way, he won't make back until the day after the Saiyans reach Earth. The Saiyan ships crash onto Earth in the middle of a huge city, and 2 Saiyans, Nappa and Vejita, come out of the ships. Nappa easily destroys a large portion of the city, and explains that the Saiyans have come to Earth to use the Dragon Balls to wish for immortality. Its up to Goku's friends, and Gohan, to defend the Earth until Goku arrives.
16: The Battle Begins; Goku, where are you?
Nappa and Vejita fly straight to the two strongest people on Earth: Gohan & Piccolo. Krillin, Tenshinhan (Tien), and Yamcha all come to help defend the Earth. Nappa asks for the Dragon Balls and tells Piccolo he's from a different planet: Namek. Nappa also "grows" six green SaibaMen from seeds, and the fighters agree to a tournament, in order to stall until Goku arrives.
17: The Saibamen Strike
The tournament between Earth's defenders and the Saibamen began with Tien defeating one of the Saibamen. Yamcha was next, and defeated another Saibaman. However, the Saiba man jumped onto Yamcha and blew both of them up; a kamikaze attack. Bulma, at Master Roshi's house, cried, but Master Roshi said they could wish Yamcha back with the Dragon Balls. Krillin, out of anger, destroyed three more of the Saibamen with an enormous fireball, and shot the Saiyans. Nappa and Vegita were unharmed, however, and Piccolo killed the last Saibaman. Nappa decided it was time to finish off the Earthlings and started to charge up his attack. Will Goku make it in time?
18: Nappa...The Invincible?
Nappa starts off by fighting with Tien. Tien trys his best, but Nappa is too strong for him. Nappa chops off one of Tien's hands, and Tien goes down. Tien's little buddy, Chazou, grabs onto Nappa's back in an attempt to kill Nappa. Chazou explodes himself, but doesn't even scratch Nappa. And, Chazou's already been wished back to life with the Dragon Balls, so it will be much harder to bring him back. Tien fills with rage, and fiercely attacks Nappa, but to no avail. Nappa easily knocks Tien aside, but Piccolo and Krillin attempt a sneak attack. They stun Nappa, but Gohan is too scared to fight, and Nappa regains his defense. Goku is almost there, but will he make it in time to save his friends?
19: Tien Goes All Out!
Piccolo and Krillin make multiple copies of themselves with the Tri-form technique and, without the aid of Gohan, fight with Nappa to no avail. Tien sees Chazou's ghost, and gets back up for one last fireball. Nappa barely notices the fireball, but blocks it just in time. Tien falls back down, too tired to fight anymore. Vegita then orders Nappa to stop fighting for three hours, so they can wait for Goku. During the break Piccolo tells Gohan he's very disappointed in him, and if he isn't going to help he should go home. Krillin convinces Gohan to stay. Nappa sees a camera man and chases the press away. He sees a huge fleet out in the sea, and decides to destroy it, for fun. Goku finally reaches the end of Snake Way, but is he too late?
20: Time's Up!!
Nappa destroys a building before returning to the fight. Break time runs out, and Goku hasn't shown up, so Krillin, Piccolo, and Gohan plan their attack. Krillin distracts Nappa while Piccolo sneaks up and grabs Nappa's tail, the Saiyan's only weak spot. Gohan prepares to attack, but Nappa is uneffected by Piccolo and gives Piccolo a strong hit on the head. Vegita says Nappa and he have evolved some, and their tail is no longer a weak spot. Krillin shoots a dicing fireball at Nappa, and Nappa is ready to catch it. Vegita tells Nappa not to, and the fireball just barely misses him. Out of anger at nearly being defeated, Nappa shoots a fireball at Krillin, seriously hurting him. Piccolo staggers up and shoots a fireball at Nappa's back. Nappa thinks it was Gohan who shot the ball and goes after him, but Piccolo intervenes. Meanwhile, Goku makes it to the end of Snake Way, and transports to Kami's floating island, where he calls for Nimbus, his flying cloud. He gets two curing Sensu Beans, and is off to help his friends. Piccolo, Gohan, and Krillin sense Goku coming, and Vegita uses his scanner to measure Goku's power level. Its over 5000! Goku and Nappa will duke it out next time on DBZ!
21: The Return of Goku
The fighting continues between the warriors and Nappa. Gohan sneaks in a strong kick and hits Nappa. Nappa fills with rage, and charges a fireball to kill Gohan with. Piccolo shields Gohan by sacrificing himself. Since Piccolo dies, Kamisama dies as well (long story), but before he does he tells Popo that the Dragon Balls on Earth are gone. There are, however, another set of Dragon Balls on Namek. Gohan gets very angry, and shoots a big fireball at Nappa, who blocks it. Nappa gets ready to step on the now trembling Gohan, when Nimbus swoops down and gets Gohan away from danger. Its Goku! Goku gives Krillin and Gohan a piece of his last Sensu bean, which regenerates their strength. Goku slowly and confidently walks over to Nappa, easily dodging Nappa's attacks, hitting Nappa every once and awhile. Its time for Nappa to get a taste of his own medicine on the next episode of DBZ!
22: Goku Strikes Back
Nappa and Goku fight on, Goku easily countering and attacking Nappa. Vegita sees that Nappa can't win this battle, and orders him to come down. Nappa stops fighting Goku, and goes after Krillin and Gohan. Goku uses his Kao Kan attacks, which increases all his senses and strength, to seriously hurt Nappa. Nappa asks for Vegita to help him up, but Vegita throes him in the air, and kills him with a huge fireball. Goku tells Gohan and Krillin to go Master Roshi's house, so Vegita can't hurt them. Goku and Vegita fly off to a remote location to fight. Vegita asks Kakarot (Goku's Saiyan name) to join him in ruling the universe, and, of course, Goku refuses. Goku and Vegita are almost equal in strength, and each is having a hard time hurting the other. Who will win?
23: Goku VS Vegita...A Saiyan Dual
Goku and Vegita continue fighting and defending, each unable to break their opponents defence. Goku tries a Triple Kao Kan attack, which could destroy his own body if he's not careful. He hits Vegita, but doesn't seriously hurt him. Vegita gets very angry, and decides to destroy the planet. Vegita uses his ? Gun attack, and shoots a huge beam at the Earth. Goku block it by using his Triple Kao Kan attack, and a Kamehameah. Goku's and Vegita's beams are equal in strength, so Goku performs a Kao Kan attack -- times 4! Vegita is sent flying up through the air, riding Goku's beam. Yajarobe, who had been watching the fight from behind a rock, comes out to congratulate Goku and claim victory with him. Goku, however, is very weak and tells Yajarobe that Vegita will be back, and probably very angry. Yajarobe runs away, and Vegita returns. Vegita tells Goku he's going to kill him with a move he learned from Goku's father. Vegita shoots a huge fireball that resembles the moon into the sky...
24: Vegeta...Saiyan Style!
The glowing ball causes Vegita to turn into a huge monkey. Goku doesn't transform into one because he doesn't have his tail; he cut it off a long time ago. Goku tries to out-manuver the beast, but he is no match for the huge ape. Vegita easily hurts Goku. Vegita is about to step on Goku, so Goku puts all his strength into one last fireball and shoots it into Vegita's eye. Vegita loses one eye, but becomes VERY angry, and crushes Goku's legs. Vegita picks Goku up, and starts to squeeze the life out of him, when Krillin and Gohan come back to help Goku. They find Yajarobe hiding, who says they're crazy and leaves. Their plan was to have Gohan distract Vegita, so Krillin can sneak up and cut of his tail. Will their plan work?
25: Stop Vegita Now!!
Gohan distracts ape-Vegita so Krillin can cut off his tail. Krillin forms a big cutting fireball, and throws it at Vegita's tail. Vegita's sensitive ears hear the fireball coming, and he jumps over it just un the nick of time. Vegita turns around and slams Krillin into the side of a cliff. Out of nowhere, Yajarobe jumps up and cuts off Vegita's tail, and runs away! Vegita reverts back to his Saiyan form. Gohan gets encouraged from his father, and begins fighting with Vegita. Meanwhile, Goku gives Krillin whats left of his Spirit Bomb, saying its their last hope. Master Roshi telepathically contacts Krillin and tells him he will know when to throw the bomb. Gohan is losing the battle when Krillin decides to throw the Bomb. Vegita jumps out of the way, and the bomb flys toward Gohan! Gohan is able to deflect the Bomb because he has a pure heart, and sends it right at Vegita. Vegita is blasted out into space, but did they REALLY defeat him?
26: The Battle Ends
Vejita's body lands, and Krillin thinks it's just a corpse. But, Vejita isn't killed so easily. Vegita tries to hurry to finish everyone off, before the last of his strength fades. Vegita notices Gohan's tail, and tries to kill the boy before he can see the artifical moon, which he had put there. Then, Vegita senses someone behind him. Yajarobe sliced Vegita's back with his sword, but but it didn't effect him much. Goku tells Gohan to look up at the moon. Yelling that he's blown it, Vegita rushes in. Too late. Trying to kill the changing monster, Vegita keeps pounding away. Then he decides to go for the tail to rip it off. However, neither Goku nor Gohan can control themselves in monkey form. Krillin and Goku tell Gohan to attack Vegita, and he does. Vegita is starting to hurt, and his artifical moon will last for a full hour. His only choice is to cut off the tail. He attacks and cuts Gohan's tail off. Gohan falls and Vegita can't move out of the way in time. Gohan's partially changed body lands on him. Vegita has enough energy to summon his space ship. Elsewhere, some men are excavating the alien craft, trying to analyze it, when it takes off. They are left sprawling, wondering what happened. Krillin picks up Yajarobe's sword and goes towards vegita to finish him. Goku tells him to let Vegita go. Vegita crawls into his ship, and blasts away. Then Master Roshi comes to get everyone.
