Information On Goten
Goten, born shortly after the Cell Saga. He is Goku's second son and was conceived shortly before Goku's death in the Cell Saga. Goten plays a big part in the series after he goes super Saiyajin at the age of 5. During his childhood he becomes great friends with Chibi (baby/non-future) Trunks. They help each other alot during their battles and eventually they learn the fusion technique with the help of Piccolo and Goku) where Goten and Trunks become Gotenks.
However while Goten always had much potential, he never fully lived up to it because of his fun loving nature and his lack of real discipline. Nevertheless he is a very important figure near the end of DBZ but by DBGT his role as a main character faded.
