Aight, how did I miss this one? So I'll be responding directly to the OP
I feel like the best way to describe this is AP vs DC. Mjolnir could definitely be 5-B (Or High 6-A if you think the statements are vague) and still not be destroying the planet with every hit. I'd like to believe the World Serpent's interpretation is the same as the myth where he's big enough to encircle the world but that's likely headcanon. And while yes, Heimdall does hype up characters, notice just how consistently the planet-level statements are brought up. Also, the Low 7-B feat was performed by a pre-Volund Lu-Bu, and all the feats performed by humans on their own weren't considered a threat to them during the very first chapter. Even Jack the Ripper with the Volund took clean hits from Hercules yet was still standing, and that guy was 9-C in his human form. It's clear just how much the Volund really amps the humans to those levels
Idk about everyone but some seem to agree this is the most straight forward statement and thus would grant a "possibly 5-B" rating. Also, the planet level statements really arent constantly brought up like they seem. And I don't care about your Volund explanation since PowerToScale did a better job at it.
Again, it's literally consistent with the multiple planet-level statements. Also, considering Shiva has 2 statements of his own, this could very well be confident that Zeus can indeed do that. Especially since just Base Zeus made Shiva sit out a fight just by threatening him. Be aware, this is the same Zeus who thought the Big Bang was a thrill, an actual phenomenon.
I'm just going to copy and paste
@Antoniofer thoughts on this since I agree with him.
Same as Hajun, destroying half Helheim is not necessary destroying clearly and half a planet, by creating havoc destroying haf of the citizen and infraestructure is already considered that the domain (Helheim) is half destroyed. Same reason can apply to Shiva's statement on Zeus, he could simply not hold himself and spread havoc in Heaven.
Or even if we literally interpret Zeus destroying heaven then it can be done over time with whatever his actual AP is.
First, the world they were on could simply just be another planet, looking back at it, it was never stated to be Earth.
What? The story literally takes place in India and nothing even implies other planet creation or destruction other than the Earth or that his backstory would take place outside of it. Even narratively it makes more sense since Shiva is from the Hindu pantheon IIRC.
So yes, he very well could've created the Earth well after fighting all the gods.
Never stated and he was a kid when Earth was already created and all we know is that Shiva lived in India.
Also, creation feats do scale to AP, this would be Planet level with Heimdall's 'on a whim' statement implying little to no timeframe being required.
On a whim simply means suddenly deciding to or something along the lines, it has nothing to do with time frames. And no, creation doesn't scale to your AP unless it has a good reason to. Here, it doesn't.
And again, back to the AP vs DC argument, just cuz their fight didn't destroy the planet, doesn't mean they don't have the AP.
Problem isn't that they didn't destroy planets in the tournament, the problem is there are no such feats even outside of them and can just as well be interpreted on a lower level.
Also, titles actually do hold meaning for gods, Poseidon was stated as being the most feared god because the gods literally piss themselves around his presence.
No, they don't.
Also, no one seemed to be against Zeus being the Grandfather of the Cosmos.
Because it's just a title and means nothing.
Also, you pretty much answered your question, Shiva only after combusting would recreate the world. He went back to the entrance because he was able to end the fight before he could combust.
Uh, no. Once he started combusting, the world would be destroyed and recreated from ash with Shiva himself burning to ash and being reborn. The myth literally contradicted itself.
The issue with this is that we never see the realms in their entirety (we only see the walls of Asgard and few city blocks, we only see a garden in heaven). But there is a map that indicates that all the realms are of the same size so it should be similar to Earth. So no, them just showing the buildings doesn't mean that's all that was destroyed, they usually mean a civilization resides there, which is why they need to reconstruct buildings so civilization can continue.
Except that isn't the context. All we know is Hajun creating havoc, destroying buildings and landscapes and then disappearing. If it was rebuilt and it shows buildings, then least amount of assumptions would just mean city level type of destruction, not literally planet level or inter galactic.
The planet-level statements as well as the powerscaling just make the statements more consistent if anything.
It doesnt. Powerscaling does the opposite if we compare them to humans. Hell, even Gods themselves vary from canon ball level to tearing the seas.
Though if you do still think that the statements are somewhat vague, then High 6-A could be a possibility.
They are vague save for Thors statement which most seem to agree would allow them to have their "possibly 5-B" ratings. Other than that they should be at least city level or whatever stadium feats someone else wants to calc. Or cloud feats Idc. (Don't even know if someone will do it, would be great)
And I have pretty much responded to your arguments made by different people so yes, this is a pretty bare bones response since I'm merely waiting for staff to evaluate it and too tired to care today.
