Goten is a fictional character in the manga and anime series Dragon Ball Z, as well as appearing in Dragon Ball GT. He is the second son of Son Goku and Chi Chi. Goten is a Human-Saiyan hybrid, just like his older brother Son Gohan.
Son Goten's natural physique almost perfectly replicates his father Goku's, even though his appearance such as hair style and clothes change from time to time. Goten is generally seen wearing an outfit that mimics his father's, with only slight differences. As in the case of the last few episodes of Dragon Ball Z, his hair has grown long, no longer looking like his father's he also wears a blue and white shirt with his name printed on it. In Dragon Ball GT, he wears a white shirt with purple jeans, and his hair is much shorter. His skin color stays lightly tanned for all of his appearances in Dragon Ball Z/GT. Goten, unlike his brother, was never shown to have a tail. This is never explained.
In Dragon Ball Online (which takes place 216 years after Dragon Ball Z, and unlike Dragon Ball GT, Toriyama had a lot of creative control over the story), it is stated that in 800 Age, Goten, along with Present Day Trunks had created the Kikoukenjutsu Sword School
