�Arrival Of Radditz saga begins with an unidentified spaceship crash landing on the earth. When the door to the spacecraft opens it is revealed that the figure is none other then Goku's older Brother Radditz. After easily disposing of a farmer with his shotgun, Radditz turns on his scouter on discovers a strong ki reading, that belonging to Piccolo. Radditz then proceeds to fly towards Piccolo. now see Goku flying on top of Kinto cloud (Flying Nimbus) with his five year old son Gohan holding on to him (first time we see Gohan). Goku is flying towards the Kame house, when he arrives Goku introduces Gohan to Master Roshi, Krillen and Bulma. Meanwhile Radditz has just caught up to Piccolo, after a little talk, blocking Piccolo's ki shot and kicking his ass, Radditz flys off to find his brother 'Kakarot', Piccolo decides to follow him. arrives on Kame House to confront his brother. Goku doesn't know him and asks what he's doing here. Radditz asks Goku why he hasn't prepared the Earth to be sold yet. He also reveals a secret that will change Dragonball forever, that Goku is a Saiyan (Saiya-jin). Goku says that he is an Earthling and he was raised on Earth, next Radditz finds out that Goku got rid of his tail (the true power behind a Saiyan) and that Goku bumped his head when he was a baby and forgot his mission. Radditz asks if Goku wants to help him take over the world, which Goku denies. Outraged, Radditz kicks the crap out of Krillen and Goku and kidnaps Gohan. When Radditz leaves with Gohan Piccolo arrives to the scene. He says that the only way Goku can beat Radditz is if Goku teams up with Piccolo, Goku reluctantly accepts Piccolo's offer. Together they fly off the find Radditz and to rescue Gohan. and Piccolo arrives on scene to battle Radditz. I'm not going to explain the scenes mainly because Radditz just beats the crap out of Goku and Piccolo easily (plus I can't remember the fights). During the fight Piccolo realizes that they can't beat Radditz hand-to-hand so he decides to power up his signature move, the Makankosappo (Special Beam Cannon). Piccolo charges up and fires it at Radditz which Radditz barely dodges. Radditz then knocks Piccolo flat on his green ass. When it looks like that the fight is over Goku grabs Radditz's tail causing severe pain to him. Goku has Radditz at his mercy but Radditz was clever enough to trick Goku into letting him go. Radditz then pounds on Goku. Gohan who is inside Radditz's spaceship, hearing his fathers cries gets all pissed off and destroys Radditz's ship. Gohan flys at Radditz and breaks through his armor. This really pisses off Radditz and he starts to advance on Gohan, this distraction allows Goku to grap Radditz from behind. Goku then tells Piccolo to charge up another Makankosappo, Which Piccolo readily agrees. Piccolo charges it up and fires it at Radditz, this time he gets a direct hit, the cannon goes through Radditz but also goes through Goku as well. This is Goku's first ever death in Dragonball. After the fight Piccolo tells Master Roshi that he's taking Gohan for a year of training, cause some point during the battle with Radditz, he finds out there are Dragonballs that can grant wishes. Radditz's scouter sends this information out to two other Saiyans, Nappa and Vegeta. The two Saiyans decide to travel to Earth the get the Dragonballs so that they can wish for immortality. This trip will take approximately one year to complete. That explains why Piccolo is training Gohan to help fight the Saiyans. Thus ends the first half of the Saiyan saga.

Arrival of Nappa and Vegeta
is not much to say about the year in between Radditz and the arrival of the two other Saiyans. Krillen, Tien, Yamcha, and Chao-zu went to train under Kami-Sami, Gohan trained under Piccolo, and Piccolo destroyed the moon :) . Goku, who is dead, goes to train under Kaio-Sama (King Kai) which is at the end of snake way. It takes him about 9 months or so to reach the end. Goku trains under King Kai until the Saiyans arrive. Goku also learns about his Saiyan heritage and about the ruthless nature of the Saiyans. Yamcha, Krillen and Caozu are training under Kami-Sama, during this time they enter a room which takes them to this far away planet. On this planet, they get attacked by these two Saiyans, after being horribly beat by them, they are brought back to the room. Finding out that it was only an illusion and that the Saiyans that are arriving to Earth are twice as strong as the two they fought the four are determined to train even harder. day, the two Saiyans have finally arrived, Goku has been wished back to life by the Dragonballs, but will arrive one day late. After the Saiyans destroy part of a city, they fly off to look for the strongest fighter on Earth, who is currently Piccolo. two Saiyans arrive to meet with Gohan and Piccolo who has just been joined by Krillen. Nappa and Vegeta decides to have some fun, Nappa plants six seeds which almost instantly hatches into six green Saibamen. Just as the fighting starts to heat up Tien along with Chao-Zu arrives followed shortly by Yamcha. Everyone decides to take place in a one on one battle between one of the Z fighters and the Saibamen to buy the time needed so Goku came come back. While all of this is going one there is a TV crew filming the fight live and everyone is at the Kame house watching. the fight all of the Saibamen are beaten, but at the lost of Yamcha, when a Saibamen attached to him and performed a kamikaze attack on Yamcha. Now it was Nappa's turn to fight. Nappa begins to fight against Tien first, and very easily beats him. During the fight Tien gets his arm cut off by Nappa, Chao-Zu then jumps into the fight and attaches himself to Nappa's back. Chao-Zu tries to end the fight by self-destructing, which he does but fails to take out Nappa as well. This enrages Tien and he gives it one last effort to beat Nappa with one arm. After Tien's defeat Piccolo and Krillen attack Nappa, but Nappa resists and beat them up also. Seeing his friends get beat up by Nappa Gohan throws a very strong ki blast at Nappa which Nappa barely blocks. This pisses off Nappa and he shoots an even stronger ki blast at Gohan. It looks like the end for Gohan when Piccolo jumps in and takes the hit for Gohan. Before his death, Piccolo tells Gohan that he has changed him and that he is no longer a bad person. With Krillen down and Gohan the only one left Nappa is about to win this fight when Goku finally arrives at the battlefield. who has a senzu bean with him gives half to Krillen and another half to Gohan. Hearing that everyone was killed by Nappa really pisses off Goku. The following fight doesn't even need a description as Goku easily kicks the crap out of Nappa. Seeing his partner down Vegeta who hasn't down anything yet, throws Nappa in the air and kills him. It's like some sort of Saiyan honor to do that. Anyway, the main event has finally come, Vegeta versus Goku. Goku tells Gohan and Krillen to leave the battlefield which they do, by themselves now, Goku powers up to prepare to fight Vegeta. fight between Goku and Vegeta is pretty evenly matched, that is until Goku starts to use his kaioken technique. This gives Goku the advantage, and he starts to beat up on Vegeta. Vegeta sensing that he is losing to a low class Saiyan tries to blow up the Earth but Goku rejects his fireball with a kaioken x4 kamehameha. This really pisses off Vegeta and he decides to use a move that he has never had to do. He artificially creates moonlight which causes him to go Oozaru and increasing his power level 10 times. Vegeta then proceeds to kick the crap out of Goku. Meanwhile, Gohan and Krillen has decided to fly back to the battle area to see how Goku's doing. is starting to lose the fight against Oozaru Vegeta when Yajirobe, the coward who was hiding the entire time cuts off Vegeta's tail causing Vegeta to transform back to his Saiyan form. Vegeta gets ready to kick some major ass when Krillen and Gohan arrives to the scene, Gohan then begins to fight against Vegeta. This buys enough time for Goku to create a second Genki-Dama (Spirit Bomb). Goku tried to make one earlier when he was fighting against Oozaru Vegeta but failed on the attack. Goku who is very weak, transfers the Spirit Bomb over to Krillen. He tells Krillen to wait until the moment is right to throw the bomb. When Krillen gets that flashing feeling he knows the time is right so he throws the ball at Vegeta. Vegeta however, dodges the ball just in the nick of time. The bomb is now headed for Gohan, but Goku tells Gohan that he can block the ball and reflect it if his heart is pure. Gohan does reflect the ball and this time the Spirit Bomb makes contact with Vegeta. Vegeta is not defeated, Vegeta is able to move out of the way of the bomb and he falls back down to Earth. When he lands he is very weak but is still strong enough to beat up Krillen, Gohan and Goku. All seems lost but somehow Gohan's tail seem to have grown back, Vegeta looks on n shock as Gohan glances at the artificial light that Vegeta created and turns Oozaru. In this form, Gohan is destroying everything around him and is able to get a couple of shots on Vegeta. Even though Gohan has no idea what he is doing. Vegeta manages to cut off Gohan's tail but Gohan lands on top of Vegeta. After Gohan to normal, we see Vegeta lying on the ground beaten up very bad. Bruised and beaten Vegeta tries to climb back into his spaceship but is stopped by Krillen holding Yajirobe's sword. Goku tells Krillen to let Vegeta go as he has learned his lesson. Vegeta climbs into his spaceship and flies off. the fight Master Roshi, Bulma, and Chi-chi arrive to the battlefield inside one of the capsule corp. planes to bring Goku, Gohan and Krillen back home. Thus ends the Saiyan Saga.
