The latest episode, episode 84, of the highly popular anime television series, "Dragon Ball Super," featured Goku starting to gather up his team of ten warriors for the upcoming Tournament of Power. However, warriors from other universes are apparently also preparing themselves for the ultimate battle royale that could seal the fate of their respective worlds.
As per a report from Blasting News, the biggest threat to Universe 7 is currently the warriors from Universe 11. The most powerful warrior in Universe 7 is, of course, Goku, but during the previous episodes, he was shown to be just an equal to the second most powerful being in Universe 11, Toppo.
It was also revealed that there is someone even more powerful that Toppo, called Jiren the Gray, as per MobiPicker. Given that Goku has yet to fully unlock his limit, it might be possible that Goku is actually more powerful than Toppo, but it is yet to be seen if he can match Jiren.
In the preview clip at the end of "Dragon Ball Super" episode 84, an additional warrior from Universe 11 was featured. As of the moment, the only known warriors from Universe 11 is Toppo and his friend Jiren The Gray. The clip, however, showed another warrior that looks quite similar to both Beerus and Champa. The cat-like warrior is seen wearing the same Pride Trooper uniform as Toppo, which means that he is definitely one of the ten warriors that will be competing for Universe 11.
The final scene in the preview clip shows Jiren in his entirely as he is meditating. The most powerful warrior in Universe 11 is even shown to have a menacing red glow, similar to that of Goku's Kaioken aura. The next few episodes of "Dragon Ball Super" will be featuring the gathering of the ten warriors of Universe 7. So far Goku has already convinced Krillin and Android 18 to join, with Majin Buu to be next on the list.
