Second son of Goku, Goten was conceived a little before the Cell Game. Goten has amazing power for a  6 year old in that he can already transform into a Super Saiyan, something that surprised and even made Gohan a little angry since it took him a long time to master it. He and Trunks are best friends, probably because they are the only ones that can play together and not hurt each other. When Buu is resurrect, and Vegeta and Gohan fail to defeat him, Goten is the worl's last hope, as he trains to master the fusion technique with Trunks. In DragonBall GT, he becomes more of a lady's man, constantly worrying  about dates instead of  focusing on training.
