Goten is the second and youngest son of Goku and Chi-Chi, and the smaller brother of Gohan. His best friend is Trunks, who is spoiled at Capsule Corp by his family. Before the Buu Saga, Goten had never seen his
father since Goku had been in the Otherworld. He has a striking resemblance to Goku and where's a similar outfit. In the World Tornament, he was beaten by Trunks after fighting in his Super Saiyan transformation. This transformation was first seen when he practiced with Gohan, saying that he wanted "to be like him". Gohan said that maybe when he got older he would teach him but Goten surprised him by turning into a Super Saiyan right there. In DBGT, he is mainly a minor character seeing as all he wants is to have a girlfriend.
In Bragonball Online, he worked together with trunks to form the Kikoukenjutsu Sword School.
