// Hmmm.... with the current debate that's going on, I'll need to look up Yubel's feats, and make sure they're canon. It'll take me a while.
For Yubel's feats we have:
the time she defeated the 3 sacred beats (AKA the 3 "phantom demons"). Who are just as powerful as egyptian gods who are planet level. And she defeated them while she possessed a weak and fragile human (Martin). She defeated them in a few seconds using only "her" aura. She didn't even physically touch them.
I took screenshots of that here (the screenshots also directly state the scared beasts are as strong as egyptian gods ... also there are screenshots of her nullifying Exodia's power (who's another planet level character) when she was in Johan's body (so weaker than "her" real body) AND weakened:

Here we have screenshots I took that show Yubel has reality warping abilities. And she can use them even without a fuctional body (when she was in her eye form). Here she changed holograms into real serpents for example:

We know she has "creation" abilities because she created at least the hundreads of death belts (aka bio-bands in the english dub):

We know it's true because once students who used them were not in the same universe than her, then their death belts started to turn into dust (and that's mentionned in Yubel's weakness on "her" profile: objects she created can continue to exist only as long as they're in the same universe than her).
Then when it comes to the force of "her" punches who can cause earthquakes, I once again took screenshots of that (she was in Martin's body btw: and he is known to be weak and fragile):

Here we have screenshots that show she can teleport "herself" and/or others on a multi universal scale:

Here we have screnshots that show she created a dark space in which she trapped Johan's soul:

+ other screenshtos related to her soul manipulation abilities:

And here we have the screenshot when Yubel claims she can send someone in an interval between space and time:

And here, I took screenshots of all time she talked about her project to fuse/destroy the 12 dimensions:

Btw: we know they're universe size because one of them is the "normal universe" who's just as big as our universe (and we know it happens in a fictional version of our universe because there are references to things that exist in our world such as the eiffel tower and many other real life existing things).
Alright so no need to search: you already have all proofs you need to see her feats are canon.
