Son Goten:

Son Goten is Son Gokou' second child. Unlike Gohan, Chi Chi does not force him to do as well in Academics. But he too is powerful, because at the early age of 7, Goten is able to turn Super Saiyajin. The only disadvantage that Goten has is that he is never able to improve upon his power, and show his full potential, therefore he never has the ability to surpass Super Saiyajin Level 1. Not much changes as he grows older.
