Goten is the second son of Goku. He is the best friend of Chibi Trunks. Goten turns Super-Saiyan at age 5. He is one year younger than Chibi Trunks. Goten and Trunks fuse and make Gotenks. Gotenks can reach SSJ-3 like Goku. Goten would have been in the GT series, but Pan closed the Capsule door on him and Goku, Trunks, and Bra left to the world of GT. Goten likes to fight more than do his work. He never signed up for school like Gohan, but he is a better fighter.
