Goten

Goten is Gohan's brother and Trunks' best friend. In a special movie their fathers fuse into Gogeta, and they follow by turning into Gotenks and perform a super ghost kamikaze attack. Like the rest of his family Goten has a huge appetite. In the Brolly story, Goten shows up and helps out his dad, Trunks, and Piccolo get rid of Brolly. In the final movie it is up to Goten, No. 18, and Trunks to finish off Brolly because Jaguar genetically cloned him.

More to come if I can find it.
