In the previous manga chapter of Dragon Ball Super, we read as we discovered that there is another power that can rival the Angels Ultra Instinct. Furthermore, this power is preferred by the Gods of Destruction’s and it’s more suitable for Vegeta’s fighting style.
Vegeta is more like Beerus, while Goku is more like Whis, an Angel and that’s why Ultra Instinct suits him. Meanwhile, for Vegeta, Ultra Instinct goes against his nature and as a result, Beerus has confirmed and alternative that will allow Vegeta to keep up with Goku.
So, what is this power? Well, it could be similar to the power that Toppo showed us during the Tournament of Power as a God of Destruction in training. However, that power was only canon in the anime and not seen in the manga. As a result, the power that Beerus is referring to could be something else entirely.
For Vegeta to learn this power, whatever it is, he will need to train under Universe 7’s God of Destruction in Beerus. However, Beerus has stated that he isn’t the teaching type in the latest manga chapter. Though, he did state that Vegeta could accidentally learn something while watching him.
I think that this is a hint that Beerus won’t directly train Vegeta as Whis is teaching Goku but will mentor him instead. Therefore, we will likely not see Vegeta sparring with Beerus but at least we will see Vegeta progress in the story and keep up with his rival.
Hopefully, we will see a glimpse of this power soon though in the upcoming arc. However, the Dragon Ball Super manga is a monthly edition, which means longer waiting for new content to arrive.
