I've read my share of comics since the 90s not very knowledgeable on recent books. The scans are debunked unless you can prove validity of them, I first agreed with the infinite-directions scans since Antvasima referenced similar earlier but
@Ovy7 proved the invalidity of it as infinite directions could still mean anything of a higher plane even and not necessarily Higher infinites or dimensions and as for the beyonder that was in secret wars II after the secret I event where he finally showed himself plus it was from "infinite-dimensional" to 3-D thing is in multiverse state didn't prove qualitative superiority over the multiverse and they could interact with him fine and even fight and give him trouble, then thus characters shown in secret wars I were impressed by Galaxy level destruction done by beyonder further more to entire event of secret wars II which he never showed quality superiority. But I feel even if he gets to keep High-1B it should be in a separate key where his one with the Beyond Realm.
My opinion is like this:
2-A up to High-1B with powers and possibly High-1B.
That's for him reducing his self from infinite-dimensional to 3-D in multiverse which would mean the Beyond Realm is possibly High-1B for it to say he reduced his dimensionality from infinite-dimensional to three dimensional.
