1. Pre-Retcon Beyonder is Omnipotent by Jim Starlin.
2. HP Lovecraft/Umineko isnt based on any real life terms of scientific knowledge you are placing REAL LIFE Terms,research, and or any theories in fictional community's that dont do logic 24/7 because RL terms are logical and more than Illogical as you state Yog-Sothoth is above infinity?......yet you claim to use scientific terms which by laws of physics/scientific evidence you cant be above Infinity which you just contradicted your own statements about how they use fake terms but yet Cthulhuverse is above infinity? That's you being hypocritical/Biased toward the fictional communities of Marvel/DC so first off.....
1. Marvel has been confirmed the many levels of infinity in their respective series/characters and to let you know the living tribunal who is LIKE Yog-Sothoth exist beyond space and time hell it was stated HE is Beyond infinity why? Because the simple terms never described his powers.
2. Megaverse/Omniverse are canon regardless of what you say Alpha as it seems you know very little of the given series and you believe what you read online which is very noticeable.
3. You failed to show proof/evidence/feats/sources of any of the fictional series you are trying to prove has Hilbert space theory where also keyword "Theory" which its speculation/assumptions and not been proven AT ALL!
