The story logic stated that he held apart the planets from colliding, not the entire universes, and only survived because he was in-between the two universes. He was consistently treated as planet level, and possible to damage by much lesser forces, afterwards.
Thor is not usually portrayed at anywhere near the level we have rated him as, due to Marvel's characteristic inconsistency. We can scale Hyperion from Red She-Hulk though, due to being rated roughly the same, if I remember correctly.
I see. Thanks. I guess I'm good with Hyperion's current upgrade. It is Thor's physical league anyway (what he was rated as before physically iirc) where Hype is now rated at, which they are portrayed to be rough equals, and he's not really known for his energy projections.
