It has been five year since Goku fought Piccolo Damiou. In this time, Goku has married Chichi, and have had a son together named Gohan, after Goku's grandfather. These years have been peaceful, but a new enemy is headed straight for their peaceful planet. Goku and Gohan at Kame House for a reunion, and everyone there is shocked that Goku has had son. Soon after Goku arrived a Saiyan named Raditz came looking for a man named Kakarot. Goku didn't know who this strange man was or who Kakarot was, but he knew exactly who Goku was, and called him by the name Kakarot. Raditz proceeded to explain Goku's origins, and how he was born on Planet Vegeta. According to Raditz he was a race made for killing. He explained how the Saiyans destroyed the inhabitants of planets and then sold them for high prices, on the Planet Trade. Raditz asked Goku why he hadn't completed his mission, and destroyed all the inhabitance of Earth. Goku at this stage was somewhat confused, and asked what the moon had to do with anything. Raditz explained that when Saiyans looked at a full moon they transformed into giant apes. This ape form, or as it is commonly referred to as Oozuru form, makes a Saiyan extremely powerful. Master Roshi then told Goku what Gohan (Goku's grandfather, not his son) had told him many years ago. He said that Gohan found the infant (Goku) in a strange pod in the wilderness near his home on Mt. Pauozu. Goku was a vicious baby who constantly lashed out at him and tried to attack him. He was uncontrollable, and as a result, one day jumped off of Gohan's back into a ravine where he hit his head. The fall would have killed normal people, however Goku had incredible recuperative skills. When Goku finally awoke, he was no longer hostile, instead he cared for the world and everything in it. Raditz then demanded that Goku rejoin his race and help destroy a planet with his fellow comrades. Goku refused without giving it another thought. Raditz then noticed Gohan, he threatened to take the five-year-old and kill him unless Goku killed 100 humans and brought him their corpses by that same time the next day. Goku tried to defend Gohan but it was useless. After Raditz had left Goku, Master-Roshi, and Krillen all were planning to attack Raditz, but right before they left, Piccolo appeared. Having previously encountered Raditz (before Raditz met up with Goku) he knew how strong he was. So Piccolo proposed he and Goku team up to kill him. They agreed and took off towards Raditz, with the others following slowly behind in an air-jet. Raditz had put Gohan in his pod to shut him up and immediately after, Gohan's power reading rose to 750. Raditz took it as a malfunction and ignored it. A few minutes later, Goku and Piccolo landed in front of Raditz. Raditz easily fought both of them. He overpowered them both with brute strength, speed, and ki level. Raditz kept attacking and after a while he shot two ki blasts at Goku and Piccolo. Goku barely dodged his, however Piccolo didn't react in time and his arm was torn off by the blast. Piccolo came up with a plan. He told Goku to fight off Raditz for 5 minutes while Piccolo powered up. Piccolo put 2 fingers up to his head and started powering up. Goku fought Raditz off as well as he could until Piccolo finally gathered enough energy. At that time, Piccolo shot a makankansappou (literally translated means screw beam of the devil) and the attack sped towards Raditz and ended up destroying a mountain in the distance. When all the dust cleared, Raditz was still standing, only with a large chunk out of his armors shoulder. Goku, who had been severely beaten, got enough energy to sneak up behind Raditz and grab his tail, which was dangling carelessly. When Goku had hold of his tail he squeezed as hard as he could. Goku told Piccolo to power up his attack again, to which Piccolo was happy to do. Raditz reasoned with Goku that if he let him go he would leave Earth and never come back again. Goku, who was very gullible, believed every word even though Piccolo was screaming at him not to listen. Goku finally let go and swiftly received an elbow to the top of his head. Raditz started attacking the already weak Goku who had no chance of even putting up a fight. Raditz tortured the helpless Goku as he lay on the ground. Gohan heard this while he was trapped in the pod, and this enraged him. He burst out of the pod, which sent debris flying everywhere. He hurled himself through the air into Raditz's chest cracking his armor and taking his power down considerably. Raditz was about to kill Gohan when he finally noticed Piccolo who was almost done with his makankansappou. Raditz went to kill Piccolo before he could fire the attack, but before he could get to Piccolo, Goku gathered enough strength to get up and grab Raditz. Raditz again pleaded with Goku, but this time Goku didn't believe a word he said. Instead, he prompted Piccolo to hurry because his ribs were broken and he couldn't hold Raditz much longer. Piccolo finally gathered enough energy and happily fired the shot that he knew was going to kill both of his enemies. The makankansappou hit Raditz and went through him and straight out the other side of Goku. You saw Goku's ki bulge slightly, then a tremendous light shot out from his back and he went hurdling backwards. Goku was shown falling with a gaping hole in his stomach gushing out blood. Both were mortally wounded and had no hope of surviving, but before Raditz died, Piccolo told him about the Dragon Balls. When Piccolo was done telling him about the Dragon Balls, Raditz told Piccolo that he had transmitted that message to two other Saiyan who were much stronger than him. Piccolo quickly killed him in a moment of great rage. By that time the others had arrived and saw that Goku was going to die. Goku said that he loved them all, and slowly faded away. Piccolo took the fainted Gohan from the hands of Bulma after he had rejuvenated his arm. After Piccolo left, Krillen was forced to take Raditz's scouter off of his corpse so that Bulma could program it into their language. Gohan finally awoke because Piccolo threw him into a small pond. Gohan did not remember how he attacked Raditz, or how he got such a huge power. So Piccolo decided to prove it to him. He grabbed Gohan's head, and flung him towards a mountain. Gohan cried for a second, then got a serious look on his face, put his hands in front of him, and shot a huge ki blast that demolished a mountain. With that proven, Piccolo took him farther into the desert to stay in isolation for 6 months. Krillen went to Goku's house to try to tell Chi-Chi about Goku and Gohan, but couldn't get enough guts to go through with it. Krillen snuck out and Chi-Chi eventually found out what had happened from Master-Roshi when she drove to his house. While Krillen and Bulma were still searching for the Dragon Balls, Yajirobei showed up. He told them not to wish Goku back for another year, and although they were confused, agreed to do so because they were Kami orders. The reason behind this was that Goku was traveling along the Path of the Snake to meet a martial arts genius named King Kai-sama. Before he left he also told them that Kami had requested to train all of the Z Senshi at his palace. All of the Senshi gathered and met Kami-sama to begin training. They all trained with each other for quite some time. After learning nothing at all from Kami-sama, and simply training together just like they would have done on Earth, they got mad and asked for something more difficult. Gohan continued training and met many friends as he trained, he met up with a robot that sacrificed his life to save to save his own, and grew stronger in some way. Near the end of the 6 months however, Gohan made a small boat and sailed across the ocean to find his mother. He was caught in a storm and thrown ashore by a huge tornado of water. Gohan was awoken by two orphan children who had given him a bed to recover in. He learned that it was a community of orphans and that they had lost their families in a great tsunami. Gohan helped them steal their food, and even avoid the foster home a few times. But finally he decided he couldn't stay away from his mother any longer and tried to sneak out at night. The leader of the orphans, who was on duty watching for the orphanage, spotted him. Gohan told him about what had happened and he decided that all the orphans were going to help take him home. They all waited the next day to ambush the orphanage van and steal it, but when the van crossed the horizon, so did police cars. All but the leader and Gohan got away, although Gohan couldn't believe that he had left them. Gohan made it to his house, and was merely a few steps from home, however, he decided to fight the Saiyan, as well as all the others. When Goku had finally arrived at King Kai's planet, there was little over 100 days for him to train. The first task King Kai had Goku do before he would be willing to train him was make him laugh. After Goku had accomplished that he had to overcome the gravity of the planet, which was 10 times that of earths. The way King Kai had Goku do this was by catching Bubbles, the monkey. After a lot of hard work, Goku finally caught Bubbles after 3 weeks and went onto the next test. He had to hit Gregory, a small insect, on the head with a huge hammer. Goku had trouble with this as well, but eventually managed to get a good shot on Gregory and passed that test as well. Now Goku could move onto the real training. Over the next few months Goku learned the Kaioken technique, and the extremely powerful and dangerous Genki-Dama (spirit bomb). All the other Senshi had trained extremely hard and improved their power levels tremendously. Finally the day arrived when the evil Saiyan arrived on the Earth. At approximately 11:53 A.M, the two Saiyan landed on the outskirts of a populated city. The two stepped out and the large one named Nappa raised his two fingers and instantly obliterated the whole city. King Kai suddenly got extremely scared, and told Goku that he had forgotten to calculate the time it would take him to get back to the check-in station. King Kai-sama had Goku immediately contact Master-Roshi and tell them to bring him back to life. Piccolo and Gohan were first to notice that Shenlong had been called. When Piccolo noticed that Shenlong had been summoned he knew that it meant the Saiyan had arrived. At 12:20 the Z Senshi began gathering. The Saiyan arrived shortly after Krillen had met up with Piccolo and Gohan. When all of the fighters had arrived, the Saiyan decided to make a game out of the whole ordeal. Since there were 6 fighters, they decided to use their last 6 Sabai-men to fight. They dropped seeds in the ground, added a strange liquid, and watched as the strange creatures sprouted from underneath the ground. The first to fight the Sabai-men was Yumcha. He had the upper hand throughout the battle, and after a short while gave the Sabai-man a near fatal wound. Yumcha, thinking the Sabai-man was dead, let his guard down. When the Sabai-man saw this he immediately jumped onto Yumcha's back and self-destructed, taking Yumcha with itself. Krillen became enraged and shot a huge ki beam headed straight for Vegeta and Nappa. Before the blast hit the two Saiyan, it split into 6 separate beams and hit each Sabai-man, except for one, and the last one hit the Saiyans, but did no damage at all to them. The last Sabai-man lunged out at Gohan from his hiding place, but was cut short by Piccolo who easily killed it. Finally it was Nappa's turn to fight. Nappa defeated all of the fighters with ease. Nappa fought all the Z Senshi, however, the only person to be seriously injured up to that point, had been Tein, whose forearm was ripped off by Nappa with a single punch. Despite this the first to die was Choutzu. The fight continued until Choutzu snuck up behind Nappa and latched onto his back. He said his goodbyes and self-destructed for the good of the Earth. When the dust cleared, Nappa was still there, without a scratch on him. Tein, enraged that Choutzu sacrificed himself for nothing, decided to perform one last Kikoho. He had a short flashback of his life with Choutzu, and all the things they had done together. He started gathering Ki in the palm of his hand, and when he finally gathered it all, yelled, "Choutzu, this is one last Kikoho." As the massive Kikoho flew towards Nappa all Nappa could do was watch and prepare for it in the split second he had to react. It hit him dead on, but once again, as the smoke cleared, there was Nappa, barely injured. The remaining fighters kept on mentioning Goku, and how if he were there they would have chance of winning. Vegeta became interested in this, so he decided to wait for this Goku to arrive and postponed the fight for 3 hours. Nappa took off because he was bored while the others waited. When the 3 hours were up Nappa returned from reeking havoc on the world, and Goku still hadn't shown up. Since Goku hadn't shown up in the time given, Vegeta decided to let Nappa battle the remaining fighters. Piccolo devised a plan between himself, Gohan, and Krillen. He told Gohan and Krillen to fight Nappa while he went around and grabbed his tail. Every thing worked perfectly, Gohan distracted Nappa, and Piccolo grabbed his tail. However, after Piccolo grabbed his tail, Nappa simply put his elbow into the top of Piccolo's head. Piccolo was down and now only Krillen and Gohan were left to fight. Krillen formed a Kienzan and challenged Nappa. Nappa, thinking it would be another weak attack, stood and watched the attack speed towards him. Vegeta yelled at Nappa and told him to duck before the attack struck him. He moved in the nick of time as the disc narrowly missed Nappa and cut his face. Nappa couldn't believe this so he formed a ki blast in his hand and threw it straight at Krillen. Krillen barely survived this and he fell to the ground paralyzed. Nappa was gathering another shot as Gohan came up and kicked him into a large pile of rocks. Piccolo, who was back up by this time, was amazed by Gohan's powers. Nappa, who was extremely mad at Gohan, gathered ki to make the same attack that almost killed Krillen. He shot the blast at Gohan and all he could do was sit and watch his impending death speed towards him. All of a sudden Piccolo jumped out in front of Gohan, and took the blast instead of Gohan. Piccolo fell to the ground, without any hope of living, and told Gohan that he was the only person he had ever cared for in his life. Gohan watched Piccolo fade away, along with Kami and the Dragon Balls. Gohan turned to Nappa with rage in his eyes and shot a massive Masenko at Nappa, which he blocked easily with his arm, however, this did nothing to Nappa. Gohan was the only fighter left standing, he had no chance against Nappa, and so he simply put his head down, and waited for his death. Nappa's foot sped towards Gohan and landed, surprisingly, hitting only the ground. Goku had arrived in the nick of time! Goku fought Nappa alone after giving Krillen and Gohan each half of a Senzu Bean. Goku easily beat Nappa, and took Vegeta to an isolated place to fight. None of Goku's attacks had any effect on Vegeta, until Goku used the Kaioken x 3. Goku jumped off the ledge he had been on, and headed straight for Vegeta. Vegeta was helpless and was thrown around like a rag doll by Goku's new attack. Vegeta enraged that he had been beaten so easily by such a low-level soldier decided he would simply destroy the Earth. He went into the sky and started gathering Ki. Goku started to do the exact same thing, he got in the stance for the Kamehameha and started muttering those famous words. Vegeta finally gathered enough Ki and yelled, "Gatling Gun." About that time Goku had finished his Kamehameha. The two massive Ki beams sped towards each other and when they met, there was a huge explosion. The two blasts were equal in strength and it was a total stalemate. Goku decided that he had to force himself to use the Kaioken x 4. Even if it might kill him, he had to for the good of the Earth. He yelled at the top of his lungs, "Kaioken, times 4," and immediately a huge shot blasted from his hands and overtook Vegeta's blast. Goku sat on the ledge, short of breath as Yajirobei came out from hiding to congratulate him. Yajirobei, unaware of how far Goku had pushed his body, gave him a friendly slap that made Goku cringe in pain. Yajirobei asked Goku if Vegeta was dead to which Goku replied that he wasn't near dead. He said that Vegeta was probably getting off of his Kamehameha by now, and that he would soon be back to get revenge. Yajirobei left without giving it a second thought. Not much later Vegeta pulled himself away from the Kamehameha and started looking for the moon. When he realized it wasn't there, he decided to go back down to where Goku was resting. When he got there he told Goku that to transform into Oozuru form, the Saiyan needed to see the full moon, but since there was none, he was going to use a ki blast that simulated the full moon. He formed it, threw it into the sky, and almost instantly transformed into Oozuru form and immediately attacked Goku. When Gohan and Krillen saw the strange light in the sky they began to worry about Goku, so they decided to turn back and see what was happening. Goku kept trying to run from Vegeta, but it was useless, finally. Goku used the Solar Flare technique to blind Vegeta, found a place that was stable where he could stand, and started gathering energy for a Genki-Dama. Goku had finally gathered it when Vegeta regained his sight and saw him. So as Goku prepared to throw the Genki Dama, Vegeta shot a blast out of his mouth that hit Goku head on, making him lose almost all of the Genki-Dama. Vegeta walked over to Goku and started toying with him. First he stepped on him, crushing the half portion of his body. Next, he picked him up and started crushing him slowly. At that time, Krillen and Gohan showed up. They tried to cut off Vegeta's tail with a Kienzan (Destructo disc) but at the last second, Vegeta heard it coming from behind and jumped, sending it under him. As Vegeta was taunting Gohan by slowly killing his father, Yajirobei snuck up behind him and quickly chopped off his tail, and then ran as fast as he could into hiding once again. Vegeta slowly returned to normal size. He was shocked that he had lost his tail, and was ready to kill whoever cut it off. Vegeta told whomever cut off his tail that he would soon die. However right now he had to finish off the remaining fighters. He easily got rid off Krillen with a few blows and preceded to attack Gohan. Gohan was a bit more formidable because his emotions were unusually high. Vegeta had very little problem defeating Gohan, and when he was finished, kicked Gohan down to where Goku was lying. Goku told Gohan that he had to fight Vegeta and that he could beat him. Gohan told his father that Vegeta was just too strong, but Goku told Gohan he could do it. Gohan reached out to touch his father and moments before their hands met Vegeta jumped down and kicked Goku forcefully in the stomach. Goku coughed up a pool blood, while Gohan just got even angrier. Gohan got up and started fighting Vegeta again, they kept fighting and Gohan even hit Vegeta once. However, while they fighting Goku called Krillen over and gave him the remaining energy from the Genki-Dama. He told Krillen how to use it and he went up onto a ledge to wait for a chance to hit Vegeta with it. He finally saw what he thought was the perfect opportunity, and threw it straight at Vegeta. Vegeta saw it at the last second, and jumped over it, sending it straight towards Gohan. Goku told Gohan to put his hands up so that he could deflect it towards Vegeta, since Gohan had a pure heart and the Genki-Dama would only hurt those who were evil. Gohan deflected it and Vegeta saw it coming straight towards him. All he could do was stare in shock, as he knew he had been defeated. The Genki-Dama hit him sending him sending speeding upwards. Gohan and Krillen gathered around Goku happy that they had finally beaten such a formidable opponent. As they were talking suddenly they saw something falling from the sky. Everyone was in disbelief when they saw that it was Vegeta. When he landed he wasn't moving so Krillen went over to figure out what happened. He thought that Vegeta was dead, so he was about to walk away when Vegeta suddenly got up. He stood up and let out a huge ki blast that destroyed everything that was within its range. Gohan was knocked out as well as Krillen and Goku couldn't do anything. Vegeta walked over to Gohan and noticed that he had a tail. Vegeta then looked up and saw the artificial moon that he had made. He realized that Gohan could become a huge problem if not dealt with then and there. He was about to rip Gohan's tail off, when Yajirobei snuck up behind him again and slashed his back with his sword. This lowered Vegeta's power level even more, and next to that it got his mind off of Gohan's tail. He got up and attacked the cowering Yajirobei. As he was attacking Yajirobei Goku told Gohan to look up at the light. Gohan finally did and changed into Oozuru before Vegeta could cut his tail off. Gohan was uncontrollable at first, then Goku started telling him what to do, and for some reason, Gohan obeyed him. Vegeta fought him as well as he could, but was doing nothing. Finally Vegeta got a chance to shoot a Kienzan at him, and cut off his tail, however, by doing this, he made Gohan fall on top of him. This was the final blow of this fight. Vegeta slowly pulled himself towards his pod that he had called. Krillen saw that he was going to get away and quickly got Yajirobei's sword and moved in for the kill. He raised the sword on the helpless Vegeta and as he was bringing it down for the deathblow Goku suddenly cut in and told him to stop. Krillen was baffled at why Goku would want to let him live, but he said that he admired his strength and that he wanted to fight him again. After a long discussion, Krillen finally gave Goku his one wish and let Vegeta go. The legendary battle was finally over, and as Bulma and the others pulled up in their air ship, every one was extremely emotional because of the losses of their friends, and the deaths of so many other innocent people. They still had one task to perform. They went and collected the corpses of Yumcha and Tein. On the ride back to the Kame House Bulma couldn't help but think of Yumcha, and how she had spent her life with him, and all she could do was cry. Later on they remembered that they could use the Dragon Balls to bring back the dead. However, then they realized that Piccolo was dead and the Dragon Balls no longer existed, it was a very sober moment until Krillen realized something. They could go to a place called Namek. He had heard Vegeta mention that the original Dragon Balls were on the Planet Namek. Everyone was overjoyed until Bulma contacted King Kai-sama and got its coordinates, calculated them, and realized that it would take an impossible amount of time to get there with their fastest space ship. As they all thought of what they could do they finally realized. They could use the space pod that Nappa arrived in.
