Goten (孫悟天Son Goten) is the second and last child of the protagonist of the series, Goku and his wife Chi-Chi, making him a Saiyan and Human hybrid. Goten was created in the series to replace Goku as Akira Toriyama wanted to retire Goku from the series, allowing Gohan to take command. However, Toriyama was forced to bring Goku back when the fans disapproved of the decision to replace him. He is Gohan's younger brother, and Trunks'best friend.

— Goku, when seeing Goten for the first time.
Goten's appearance is very similar to Goku's childhood look, including messy, unkempt hair and a playful face. He also wears a similar Gi to Goku's. However, Goten's appearance drastically changes as he grows older, resembling his brother Gohan more than his father as a teenager, he has the same long messy hair as Gohan at a younger age. Towards the end of Dragon Ball Z, Goten is seen with a shaggier hairstyle. He also shares the Saiyan appetite of his father.
Goten is the second son of Chi-Chi and Goku, and younger brother to Gohan. Goten is born shortly after the Cell Games Saga, and did not met his father Goku until he reached the age of seven. Goten is not pushed in school as much as Gohan is and instead is trained in martial arts by Chi Chi. The reasons for this are never fully explained, but it seems to have something to do with Goku's death.
Goten is incredibly strong as a child, far stronger than either Goku or Gohan ever were at his age. Chi Chi first discovers that Goten can become a Super Saiyan at only seven years old, making him the youngest Super Saiyan ever at that point. When Gohan asks how his transformation occurred, Goten said that he was learning Martial Arts from his mom. The ease at which he does so has been a matter of controversy, seeing as it took years for Goku, Vegeta, and, to a lesser extent, Gohan to obtain and master the technique. Whatever the reason, Goten displays exceptional power at a young age, rapidly increasing his strength. Goku was not a Super Saiyan when Gohan was conceived, but he is at the time of Goten's conception. During Goten's childhood he is good friends with Bulma and Vegeta's son Trunks, who he would have "fight games" with. This serves to increase their respective strength significantly, compared to the other Human-Saiyan hybrids that are seen at that age.

— Goten questioning Gohan.
Goten's first appearance in the series is when he is seven years old. Discovering that his father Goku will be returning to Earth for a day to compete in the 25th World Martial Arts Tournament, he trains with his older brotherGohan for the event. During this training is when it is discovered that Goten has already mastered the transformation of Super Saiyan, and ironically, it is also discovered that Goten is not able to fly (something Gohan describes as "learning how to run before you learn how to crawl"). Gohan trains Goten in fighting and flight, along with his friend, (and later on, wife) Videl.
Goten meets Goku for the first time at the tournament. In the manga, he is rather shy upon first meeting his father, but in the anime, he embraces his father and they play airplane for a little bit. Goten then competes in the Junior Division. He and his best friend,Trunks, both make it to the finals with ease and battle each other. The two powerful, young Saiyan warriors place rules limiting their powers during the fight, prohibiting their Super Saiyan transformations. Trunks comes out victorious due to breaking the rules and transforming. With the two boys wanting more of a challenge, they disguise themselves and enter the Adult Division, as Mighty Mask and are later exposed by Android 18.
After Gohan is attacked, and the Z Team pursues the attackers, Goten and Trunks fight Android 18 and Mr. Satan in a battle royale. They are disqualified when Android 18 exposes them by destroying their costume. Goten and Trunks leave and are informed by Videl that Gohan and the others are in pursuit of an evil wizard named Babidi who is attempting to awaken his monster named Majin Buu.
The two fly toward Babidi's Spaceship, and upon arrival see that Piccolo and Krillin have been turned to stone by Dabura. Trunks breaks Piccolo's statue, and is afraid he might have killed him, but Piccolo regenerates himself when Dabura is killed by Majin Buu and he reverts from his stone form along with Krillin. With Gohan and Goku knocked out, Vegeta arrives to fight Majin Buu, only to be severely beaten by the monster. Goten and Trunks attempt to help Vegeta, but Vegeta knocks the boys unconscious, knowing that Majin Buu is too strong for them to help him. He then blows himself up, hoping that will finish him, but fails, as Majin Buu regenerates himself.
Goten is taken to Kami's Lookout to take refuge from Majin Buu's assault on the world. Babidi makes an announcement to the world to tells him where Piccolo, Trunks, and Goten are hiding. The boys wake up and attack Mr. Popo. Goku stops them and tells them that Vegeta and Gohan are dead. Goku teaches them the fusion technique with remainder of time he has left on earth. Babidi tells the world that he is going to West City to blow it up. Trunks rushes to the capsule corp to get the Dragon Radar. Goku intercepts Babidi and Buu to give Trunks time to get to Capsule Corp. Goku shows them Super Saiyan 3 and starts to fight Majin Buu. Trunks got the radar and Goku returned to the Lookout. Goku teaches the boys the fusion technique and shows them Super Saiyan 3. Fortuneteller Baba tells Goku his time is up and leaves the rest to Piccolo. Goten hugs his father one more time before going back to Other World.
A day later, with Goku in Other World Piccolo teaches the boys the rest of the fusion dance. After two days, Goten and Trunks are ready to fight Majin Buu. Goten then witnessed Super Buu turning his mother to an egg and crushed, thus prompting Goten to train as hard as he can. They fuse and create the warriorGotenks, who fights Majin Buu twice, almost defeating him. Gotenks is absorbed by Super Buu after Gohan arrives from the Sacred World of the Kai's (being there training) to assist the boys.
As 10 years pass, Goten is trained by Goku, and then forced to enter in the 28th World Martial Arts Tournament. Due to Goku and Uub's departure, the tournament is cancelled, and Goten and Pan decide to fight to entertain their family and friends, with Pan emerging as the victor (due to Pan being Goten's niece and four years old, Goten allows Pan to win). Goten in the end of Dragon Ball Z does not exactly look like Goku anymore because his hair changes but he continues to retain Goku's facial features. Though it is the same at the front of his hair, the back Goten's hair has shown to have grown slightly. Goten also wears the same gear with the exception of removing his long sleeve blue shirt from his gear.
Goten was intended to fight Majin Buu at the tournament's line up, but due to Goku and Uub wrecking the arena, the tournament was cancelled. In the last few moments of Dragon Ball Z Goku approaches Goten and Trunks and tells the two that he will be leaving to train Uub and for both Goten and Trunks to continue their training. Goku states that in the future, Uub would be looking at the two Saiyans (Goten and Trunks) for guidance.
In Dragon Ball GT, Goten has a girlfriend named Valese. Later on, he was supposed to aid Goku in the search for the Black Star Dragon Balls, but he was left behind in the Black Star Dragon Ball hunt when Pan went aboard the spaceship - which should have carried him, Goku and Trunks. But an eager Pan hit the launch button before Goten could get on board. Like the other Z Warriors, it is unknown what Goten was doing during the Black Star Dragon Balls search. Probably still training, and spending time with his girlfriend Valese are the only obvious clues as to what Goten was doing during the search of the Black Star Dragon balls.
On the trio's homebound trip back to Earth with the complete set of seven Dragon Balls, Goten encounters the parasitic Baby, and is forced to fight him. When Goten tries to destroy Baby with a Kamehameha wave, Baby liquefies himself and invades Goten's body, taking advantage. Continuing in his search for Vegeta, Baby Goten returns to Capsule Corporation, where he encounters Bulma, Chi-Chi, Videl and Gohan, who are unaware that Baby has taken control of Goten. Sensing Gohan's superior strength, Baby makes plans to transfer himself into Gohan. Baby Goten punches Gohan, but the others shrug it off as sibling rivalry, and Chi-Chi requests that they "take it outside".
Once in a secluded place outside, Gohan reveals that he knows Goten has been possessed, and Baby Goten launches an offensive against him. Not wanting to injure Goten, Gohan refuses to fight back, but is forced to transform into a Super Saiyan 2 to ward off Baby Goten's attacks. Baby uses the opportunity to transfer himself into Gohan's body.
Gohan and Goten appear at their house and they start to fight Goku and Pan right away. Goten powers up to a Super Saiyan and Gohan to a Super Saiyan so that they could force Goku to fight them. Gohan even promises to kill Pan, and he knocks her out. This makes Goku mad, and he starts to fight at full power, but just before he launches his Kamehameha wave at Goten and Gohan, Videl and Majin Buu show up and explain what has happened. After being revived by the Sacred Water, Goten helps restores Goku's Super Saiyan 4 powers, along with Gohan, Trunks and Pan. Soon afterward, Goku finally defeats Baby, and Goten assists in evacuating the Earth before its destruction (due to negative energy from the Black Star Dragon Balls, which had been used by Baby to create a New Planet Tuffle).
Goten is seen in a restaurant with Valese when an interview with Hercule shows up on a television in the restaurant. Hercule states that he is going to retire. Goten comments on the interview, stating, "And as long as I don't enter, I won’t have to take his place" (meaning the tournament would be a breeze for him, and he can surely become champion if he competes). Goten is seen in the city with Valese, and as soon as the villains from hell appear in the city, Goten, along with the rest of the gang, fight the villains that escaped from Hell. Most of these fights are easily won by the Z-Fighters. Immediately after destroying the villains, Goten, Gohan, Trunks, Vegeta and Majuub team up to try and take down the powerful Super 17. They attack altogether, but cannot take down the Android, even in their Super Saiyan forms. Goten is then seen, when Old Kai is explaining to Goku about the negative energy of the Dragon Balls. When Goku decides to fix the problem at hand Goten and Gohan both wish to help their father, but Goku insist he needs to do it on his own.
Goten (along with Majuub) helps to save his father's life during his battle with Syn Shenron. The Z Warriors then appear ready to fight the Dragon, but Goku has a better idea. Goku asks for Goten, Trunks and Gohan to give him their Super Saiyan energy, while Majuub tries to hold off Syn Shenron. Goten, along with Trunks and Gohan, helps to restore Goku's energy during his fight with Syn Shenron. Goten, Trunks, and Gohan try to help Goku and Vegeta fuse by holding off Omega Shenron. They succeed, and Goku and Vegeta fuse intoGogeta. Later on, Goten watches as Omega Shenron attempts to destroy Goku and Vegeta and says, "I can't take it anymore.". He goes to help, but is stopped by his older brother Gohan. Later on, when Goku is presumed to have been killed by Omega Shenron, Vegeta decides the Earth's best bet is for him to try and defeat Omega Shenron while everyone else escapes. Before sending them off, Vegeta requests that Goten, Gohan, and Trunks continue the fight if he fails. The three half-Saiyans say goodbye to their families and decide to go back to help Vegeta in the fight. They are all easily defeated, but they do succeed in distracting Omega long enough for Goku to charge his Universal Spirit Bomb which destroys the Shadow Dragon. Goten is last seen taking his mother back home after the fight and telling her his father will probably come back when he gets hungry. Goten is the only warrior who seemed relaxed and confident that Goku would return, unlike the other warriors. This shows that Goten's father-son relationship with Goku has a lot of trust, understanding, and faith.
