The Tournament of Power is not the last Arc in "Dragon Ball Super." Just before the start of the Battle Royal, this hint of what is in store for the popular anime is announced by TOEI Animation.
"Dragon Ball Super," episode 86, showed that Dende talked to Goku regarding a young boy possessing an exceptional talent in Martial Arts. This boy named Uub is said to be living in a certain village and believed widely as evil Majin Buu's reincarnation. Soon, Goku and the so-called reincarnation of Majin Buu will cross each other's path.
For the avid fans of "Dragon Ball Super," it will be noticeable that it is not the first time Uub is introduced in the series. For countless times, the boy was already mentioned, however, he was not put under the spotlight or have not received much attention. On the other hand, for those who are not familiar with Uub, he came from an underprivileged village.
According to US Blasting, he then joined the tournament in order to get the prize money. Through that competition, Goku started to notice Uub because he is special with a bit mysterious skills in Martial Arts. Both of these powerful beings showed their talents in the tournament, fortunately, they still end up being friends. There is also a little foreshadowing on who the real Uub is in Episode 86.
Dende did not directly state that he was talking about Uub but the eager followers of the series already hinted that it was referred to the boy from a poor village. Dende called him the good reincarnation of evil Majin Buu. According to some theorists, it was believed that when Majin Buu died, his DNA possibly scattered and then transferred to another being.
Fans are also speculating that in his name alone, Uub when reversed it is Buu. It can already be guaranteed that Goku and Universe 7 will be triumphant in the Battle Royal but it is still unclear what would the Universe 7 do in order to win against multiverse's other members. In addition, Cali The Female Broly is speculated having a link with Uub and Universe 6. Fans have a lot to look forward in the upcoming episodes of Dragon Ball Super.
