I'm of the opinion that Marvel's High 1-A scaling is kind of rough right now.
I don't think it makes sense for characters like Storm or Thor to scale above Multiversal Abstracts at all, all of the things used to scale them to that level seem like enormous outliers to me, Yggdrasil should not scale above the Living Tribunal that is only ever implied one time in a non-Thor comic it makes no sense at all for it to even be above Uni Eternity because Thor absolutely does not scale to Abstracts that is never implied anywhere in any story. But, I digress, that's not the topic of discussion now, so I'll drop it.
For this specific situation, I don't really know. The actual Black Winter story makes it look like Thor used up all the power, since it says Thor unleashes
all of it and immediately afterward reverts to his normal form and never enters his Herald form again. So, I have some questions before I decide which side I'm on here:
- Is the idea that Herald Thor absorbed the full power of Lifebringer Galactus, and so after he kills the Black Winter retains all of that power and continues to scale to High 1-A?
- Where does the evidence that it is Herald Thor as opposed to Odinforce Thor in the Knull fight come from? I don't see anything in Knull's justifications.
- The other piece of evidence shown that Thor kept that power is a fight against Hulk (which admittedly I have not read), but I don't see any indication in those scans that he has his Herald powers.
Regardless of the conclusion this thread reaches, I think both profiles need better explanations for the High 1-A tiering. Knull's profile needs to prove it is High 1-A Herald Thor that he is fighting, and Thor's profile needs to indicate the High 1-A tiering is something he keeps and isn't just a one time attack.
