Movie 12 is by far the best animated Dragon Ball material ever created.
Moving back to Super, we now know that Vermout is stronger than Beerus, and that Jiren is stronger than even Vermout.
So, combining all the material at our disposal, excluding Zeno, the Grand Priest, the Angels and the other Gods of Destruction, SSB Vegetto and Jiren are currently the only two characters who are confirmed to be stronger than a God of Destruction (and, maybe, also anime Merged Zamasu could probably fit in here).
I am of course assuming this is Jiren Whis was talking about, since 3/4 of the intro is dedicated to him and to Goku.
This fact is interesting also for two other reasons:
- It confirms once and for all that there are Gods of Destruction who are stronger/weaker than the others (see the supposed Vermout > Beerus > Champa power chain). Regarding this point, I still stand by my opinion for which Liquir is the strongest God of Destruction (or, at least, one between Liquir, Ivan and Gene is).
- It is basically telling us that the new form that Goku will reach will surpass Beerus.
