Uub

Uub is the human reincarnation of Kid Buu. He is the eldest of five children and martial arts pupil of Goku. Uub is very timid in his personality, despite his amazing power, becoming frightened at someone's slight expression. However, after training with Goku for many years, he becomes a confident fighter, wanting to make sure all evil is vanquished. Like Goku, Uub is pure of heart as he has the ability to ride the Flying Nimbus. He trains with Goku for many years.
