Unlike Gohan, Goten manage to merge into Super Saiyan at age 7 along with Trunks who was young at the time. He like to fight but by he reach teenager age he lost interest and Chichi tries to make him study unlike Gohan who continue to fight on the team. Goten would rather find himself a girlfriend in which he tries to do so. Without any doubt he probably grow up and look identical to his father Goku but still would fight.
Actual
he looks really cute doesn't he. The grown up version of Goten doesn't
look the same as his father anymore but more like Gohan with his first
shaggy hair style. I think he does about 3 out of four power levels.
