Goku

Origin

Baby Kakarot was born while his father Bardock and his warrior team were on a mission to conquer planet Kanassa and kill all of its inhabitants. Kakarrot was a very weak baby, compared to the norm for the Saiyan race, so he was sent to a planet with weak inhabitants (Earth) to exterminate all the life there. This was done because Saiyan warriors are needed for harder missions, so they use their children Saiyans to exterminate their unworthy opponents.

Youth

Kakarot was found by an old man named Son Gohan in a small space craft. Gohan tried to raise the young boy, but Kakarot was extremely hostile and strong by human standards. During a trip one day, young Kakarot fell down a deep ravine and bashed his head. The permanent amnesia from this fall prevented the young boy from completing his initial mission. He was named Son Goku by Gohan.

He had amazing strength, speed, and loved fighting, so Gohan trained him in the ways of martial arts. Young Goku even had a tail which resembled a monkey's tail. This tail would allow him to turn into a huge ape at the sight of the full moon but Goku had no memories of anytime he has ever gone into that form (Oozaru) and was completely unaware of this until later told by Vegeta. It was this form that killed Gohan when Goku accidentally stomped on him.

After Gohan's death, Goku would meet the genius girl Bulma Briefs who sees the four-star Dragon Ball his grandfather gave him and told about how there were the seven mystic artifacts that could grant one wish. Goku went with her and met several characters; Master Roshi, the Turtle Hermit, Yamcha the desert bandit and his shape shifting cat companion Puar, Ox-King and his daughter Chi-Chi, and Oolong, a shape shifting pig. On the journey, they manage to collect six of the Dragon Balls.

In the end, the evil imp Pilaf and his cohorts Mai and Shu would gather all seven of the Dragon Balls so that Pilaf can rule the world. After Oolong wished for a pair of panties, Pilaf ordered him and his friends executed and it was at this time that Goku saw the full moon and became Oozaru, smashing up Pilaf's castle in the process. Puar managed to cut off Goku's tail and after that debacle, Goku decided to train with the venerable old Master Roshi. After Goku and Kuririn brought him a multiple-personality woman named Lunch, Roshi began to train Goku and Kuririn, a Buddhist monk also seeking training, in the ways of the Turtle Hermit and taught them the legendary energy blast: the Kamehameha, which Goku had already known from witnessing it. Goku and Kuririn would then test their skills by entering the 21st Tenkaichi Budokai. Goku fared well and defeated Giran and Namu before being defeated by Jackie Chun, his master's alter ego.

After the Tenkaichi Budokai, Goku traveled around the world to find the Dragon Balls, but a military criminal organization known as the Red Ribbon Army also wanted them for world domination. Goku found two Dragon Balls after defeating Colonel Silver and General White and also managed to get one while escaping General Blue. He would later fight hired assassin Tao Pai Pai and defeat him before storming the Red Ribbon Army HQ and killing Commander Black, the new leader of the organization, taking the two Dragon Balls the Army had. 

After defeating the Red Ribbon Army and finding the last Dragon ball, Goku once again entered the Tenkaichi Budokai and made it to the finals, defeating King Chapa, Panpoot, and even Kuririn in the process. His opponent was Tenshinhan, prized student of rival Crane Hermit and the match ended with both flying out of the ring and Goku losing by hitting a truck and downing first. After the match, Goku made a horrible discovery; that Kuririn had been murdered. Goku rushed out to confront the killer who had also stole his Dragon Ball and it turned out to be Tambourine, an offspring of the recently freed Piccolo Daimao. Goku was defeated and lost his Kintou'n cloud in the process. He then met Yajirobe, a mountain samurai, and the two would later venture for the Super God Water after Goku had killed Tambourine and lost to Piccolo Daimao. After drinking the potentially fatal water, Goku's strength had extremely increased and he saves Tenshinhan from the youth-restored Piccolo Daimao. Goku has a better chance in the rematch and kills the demon with one punch, but Piccolo Daimao spits out an egg with his essence in it.

 Adult Life

As an adult, Goku married a woman named Chi-Chi and had a son named Son Gohan.

Goku led a relatively peaceful life until a Saiyan warrior named Raditz landed on the planet Earth. Raditz revealed himself to be Goku's brother and told him of his original mission on Earth; to exterminate mankind. Goku refused to join Raditz in the extermination of Earth's citizens. So as an incentive to fight him and reveal his true Saiyan roots, he took Goku's newborn son Gohan hostage and decided that if Goku wouldn't fight for him and destroy Earth, then he kill the boy. To make things more complicated, Goku's old nemesis Piccolo showed up as well, but to help Goku fight the Saiyan as he disliked him too.

Goku and Piccolo fought side by side in an attempt to defeat Raditz but the Saiyan was three times stronger than his brother. Goku would have to sacrifice his life by holding Raditz in a full-nelson, giving Piccolo time to kill them both with his Makankosappo beam. Afterwards, Piccolo would tell Raditz that Goku would be revived via the Dragon Balls and Raditz transmitted the information over to his Saiyan comrades, giving Earth a new threat.

After death, Goku was allowed to keep his physical body and chose to travel to Kaio-Sama to train under him. Kaio-Sama's planet had many times Earth's gravity and helped Goku to become stronger. Goku left Kaio-Sama's just in time to fight the Saiyan warriors Vegeta and Nappa who had landed on the planet in search of the Dragon Balls. By this time, Nappa had killed Yamcha, Chaozu, Tenshinhan, and Piccolo before being defeated by Goku's new Kaio-Ken technique.

Goku would then fight Vegeta and would lose the match when Vegeta made an artificial moon to transform himself into an Oozaru and squashed the hero. Yajirobe would then intervene and cut off Vegeta's tail to revert him back. Luckily, Goku had prepared a Genki Dama and while Gohan fought off Vegeta, Goku transferred the Genki Dama to Kuririn who managed to hit Vegeta with it. But the Saiyan had survived and it was when Gohan's tail grew back and the moon transformed the boy too that Vegeta would be defeated, crushed by Gohan's body. Vegeta would then flee the planet at Goku's discretion and the planet was safe. However, Piccolo was dead and without him, the Earth Dragon Balls were useless, so Gohan, Kuririn, and Bulma traveled to Namek while Goku came behind them in training.

Unfortunately, Vegeta also came to Namek for the Dragon Balls to achieve his goal of eternal life. Vegeta's former master Freeza had also arrived on this planet seeking eternal life, having learned of the Dragon Balls from Vegeta's scouter. By the time Goku arrived, Vegeta had allied with Gohan and Kuririn and the three had taken a beating from Recoome, a member of Freeza's elite Ginyu Special Force. Goku saved the three and defeated Recoome with one elbow. The Saiyan then fought Jeice and Burter and mystified Vegeta that he might be a potential candidate for the legendary Super Saiyan status. Goku defeated Burter with two quick strikes and Jeice would flee and arrive with Captain Ginyu, the leader of the Special Force. Goku fought Ginyu and revealed to him his Kaio-Ken and Ginyu fancied Goku's body, using his body change ability to switch for it. Goku managed to get his body back and threw a frog into Ginyu's change beam when he tried to steal Vegeta's body, defeating him.

Goku would then recuperate in the rejuvenation chamber before fighting against Freeza, whom he could not defeat even with the Kaio-Ken technique. He tried using the Genki Dama, but Freeza survived and killed Kuririn before Goku's eyes. Goku was filled with angst and hatred and he had become what had been considered a legend; a Super Saiyan.

But a mysterious young man came to confront them first. Both Freeza and Cold were clearly outmatched by the youth, who had revealed himself as a Super Sayian, and are defeated in a matter of seconds.

The young man then goes to the Z-Fighters and tells them that Goku would land on Earth soon. Goku did land, having escaped Namek via a Ginyu Force space pod and with a new technique learned from Planet Yardrat: Instant Transmission. The youth is Future Trunks, and says that two Androids will be here in three years. He gives Goku heart medicine, claiming that he died of a heart virus in another time line and this would save his life. They all go their separate ways and start their training. After three years, Goku and the Z-Fighters face off against the Androids and Goku would fight against Android 19. He then caught the heart virus and would then be saved by Vegeta who had become a Super Saiyan himself. After healing, Goku would make ready to train with his son Gohan in the Hyperbolic Time Chamber for quite a while. While waiting for Vegeta and Trunks to finish, an evil bio-android from the future named Cell was wreaking havoc across Earth to absorb the Android units 17 and 18. The Hyperbolic Time Chamber was where Goku and Gohan learned how to maintain their Super Saiyan limits, and where Gohan learned how to manipulate his Saiyan strength. This was also how Goku and Gohan became able to hold themselves in these forms for elongated periods of time.

After Goku and Gohan got out of their training time in the Hyperbolic Time Chamber, they decided that since they still had much time left, they would just stay and relax until the tournament that the evil Cell had set up began. At the Cell Games, Goku would fight first and would then give the fight to Cell, knowing that he cannot win.

Goku had known since Gohan was a child that his strength comes from his anger. He was intending to wear down Cell enough so that Gohan could finish him off. Gohan had indeed become so powerful that he reached Super Saiyan 2 and broke down Cell, even punching Android 18 out of him. Cell then started to self destruct so Goku quickly used the instant transmission to teleport the Android and himself to Kaio-Sama's planet. He sacrifices himself so that Earth is safe, but Cell was able to regenerate and regain his Perfect Form. Cell would then make ready to annihilate the entire world and it was up to Gohan to defeat him. Gohan, with the help of his father's coaching and Vegeta's interference, would win a Kamehameha power struggle with Cell and destroy the vile Android. When the Z-Fighters gathered the Dragon Balls to wish everyone back to life, Goku tells them that he thinks the world would be safer if he stayed dead.

Low and behold, it is not until Goku gets a day to walk among the living that Babidi comes and resurrects Majin Buu. earlier that day Goku had met all of his best friends, like Krillin and Vegeta, along with his sons Gohan and Goten, who he'd never met before. During the World Martial Arts Tournament, Two fighters with an M insignia in their forehead stole some of Gohan's power and fled. Goku and the others followed them to Babidis ship. After the fighters gave Babidi the power they had stolen they were immediately killed. Goku, Vegeta, and the Supreme Kai went into Babidi's ship where they faced a few trials of combat. Goku fought a creature that came from the darkest corner of the universe. The creature had the ability to absorb energy. Once Goku realized this, he powered up and let the demon absorb his power until he exploded. Vegeta was secretly trying to get Babidi to see that he was evil so he would increase his power. Babidi noticed and did so. Babidi transported them to the World Martial Arts Tournament where Vegeta proved he was truly evil by blowing up part of the arena in an attempt to gode Goku into a fight. Goku asked Babidi to transport them to a place away from people to fight Vegeta. He transported them to the mountains. Goku and Vegeta went blow for blow until they realized that Majin Buu had been released, then Goku tried to persuade Vegeta to partner up so they could defeat Majin Buu. Vegeta agreed but when Goku went to grab some sensu beans, Vegeta knocked him out. Vegeta gave his life trying to defeat Majin Buu, but afterward's when Goku awoke he had to go back to the afterlife because his 24 hours were up. Gohan would later be trained by the Supreme Kai and would remove an ancient sword of power that released an elder Kai. The elder Kai would later exchange his life for Goku's afterlife so Goku could go to earth and find some one to use the Supreme Kai's fusing earrings to permanently bond with. Goku fused with Vegeta after his resurrection, becoming Vegito. In the end Goku used his Spirit Bomb to defeat Majin Buu's original form (Kid Buu). Before Kid Buu's defeat, Goku asked that Kid Buu be resurrected later in life so Goku would have the chance to fight him again. Years later Buu was resurrected as a boy named Uub, and at a martial arts tournament Goku tried antagonizing Uub into releasing his hidden power. Goku would soon stop the fight and take Uub off to train.

Powers

In Dragon Ball GT, he achieves the final Saiyan transformation called Super Saiyan 4. A Super Saiyan 4 is the most ultimate form of a saiyan, but it only can be achieved by a pure blooded saiyans such as Son Goku or Vegeta. To achieve Super Saiyan 4 for pure blooded saiyans, they must first achieve a Super Saiyan and then transform into a golden oozaru. Once the saiyan has gained self-conscience, he/she then can now transform into a Super Saiyan 4. The aspects of a Super Saiyan 4 is that it gives more power (obviously) and other things that powering up gives. Unlike the other Super Saiyan forms, a Super Saiyan 4 does not have that draw back of reverting back to normal form when a saiyan is either too worn out or knocked unconscious. The only draw back of a Super Saiyan 4 is the tail, the series has never shown what happens to Son Goku ot Vegeta when their tails get cut off, but if an oozaru gets revert back to normal, then a Super Saiyan should do the same.
