Gorr rapes the shit out of Worldbreaker Hulk.
Current Thor was coming dangerously close to replicating Worldbreaker Hulk's sole feat of note, and Gorr weathered those blows, before proceeding to defeat three Thors, one of whom was more powerful than Worldbreaker Thor and at least a hair from Skyfather status.
Gorr has slaughtered entire Pantheons, and don't forget, he did in fact beat Old King Thor's ass so bad over a period of hundreds of years to the extent that said Thor's Thorforce was nearly depleted.
So he basically crippled Odin, is what I am saying.
Anyway, Gorr eats WBH.
