way he acts, he is very innocent. Goten also eats a lot.
Unlike Gohan he isn't responsible, and he doesn't study.Chichi never makes him study and instead she trains him
a little.
Goten's best friend is Trunks. They are both always getting in trouble because of Trunks' great ideas.
Gohan taught Goten how to fly before the Budokai, Gohan was surprised whn Goten turned SSJ.
Goten lost the Budokai against Trunks, and he was very mad, but Trunks promised him that he would give him
3 of his toys if he would just forget about it, which Goten of course accepted.
Later in the Budokai they stole Mighty Mask's costume so they could participate in the adults Budokai, but
Juuhachi-go figured out who they were and beat them easily.
Goten also fought against Majin Buu, and he also died once in the series.
Ten years later he participates in the Budokai and he is beaten by his 4 year old niece Pan.
In Dragonball GT he was supposed to go along with Trunks and Goku to space to search for the Dragonballs
but Pan launches the spaceship before he gets in, so he satys in Earth.
Later he fights against Bebi and the Evil Dragons.
