Ten years after the end of DragonBall Z,
Goku gets turned into a child again by a wish Pilaf made. The only
way Goku can get back in his normal state is by finding the Black
Star dragonballs scattered across space. Goku, Pan , and Trunks go
on journeys battling minor villains. At one planet, the DragonBall
gang stumbles across Baby. Baby sneaks on board and lands on Earth.
Baby takes over bodies in hope of finding a good host. Baby first
uses Goten and Gohan as hosts, but he finally finds the most
powerful host, it is Vegeta! Vegeta now turns into Baby-Vegeta. A
great battle between Goku and Vegeta begins. It turns out Goku is no
match for Baby-Vegeta. Then Kaiousin pulls out Goku's tail, hoping
he can go into Oozaru stage. It works, but Goku still cannot defeat
Bebi-Vegeta, who now is Super Bebi (Oozaru Bebi-Vegeta). Then
something weird happens, Goku takes control of his body now and
transforms into SSJ4 Goku! Goku soon defeats Super Bebi.
