I am distinctly against this upgrade and RoR being planetary currently for a multitude of reasons. And apologies about the formatting too still new with these forums.
Forgive me, I need to write rant piece before I point out issues with the scaling of RoR's AP I want to point out for those who care at all; Jormungandr does not translate to World Serpent directly it was a title given to it for encircling Midgard. Jormun is for something vast large or super human, gandr meaning river, serpent, staff or a few other variations... Jormungandr just means "REALLY BIG SNAKE" or "Vast River" essentially. Thor PICKED IT UP when it was in the shape of a cat in the epics and fished it up too before fighting the great serpent during Ragnarok to a mutual death in the Edda Prose, while in chapter 5 page 18 of Record of Ragnarok we have a SINGLE mention of Jormungand (no R I guess for RoR's big snake) being called the World Serpent. We need MORE info about RoR's World Serpent I feel before the respectable mod team goes signing off on something like this, after all you could easily have a "World Serpent" be of drastic size differences, it could be several mountain ranges long.. it could be the size of the solar system, we have no confirmation it reached around the world only that its title was that of the World Serpent, are we going to go around granting things upgrades based on titles alone with no substantiation outside of the name? I'd be more than happy to have 5-B and 5-A for Thor and those equivalents of his strength or greater but we are going off of a single name and shaky evidence of them saying "they're going to destroy everything cause The Biggest Most Murderest God is so cool woah"... a lot.
Ranting about nominal miscategorizations aside...
To pull all this together: The arguments for the 5-B and 5-A and my rebuttals are as follows:
1)Jormungand from RoR which we have no way to confirm if it actually could circumnavigate the planet like the Calc suggests currently outside of the assumption based from its name which is shaky at best and if we want to be picky about names isn't even Jormungandr. It just has the title of World Serpent... as Hajun had the title Demon Lord of the Sixth Heaven, crap do we have to scale him to Heaven?
2)While the mention of eradicating humanity has been mentioned plenty about how easy it would be we do not know the method, as someone above mentioned it could be through ritual, as I mentioned it could be through a device assuming it is from their AP
IS a stretch. One of the earliest points in the series is how obscenely proud and arrogant the Gods of RoR are, even the 'Wise' gods of the verse are on some scyophantic 'Yeah I'm the best tho' energy otherwise there would not have been a unanimous vote to kill all of the Humans, and even then.. it is kill the humans
not destroy the planet
3) Zeus is an obscene powerhouse of a God, his statement from Original poster about destroying the heavens was in his Adamas form which we have no way of seeing if others scale to his form or the statement from that form in their base or empowered forms. Shiva is saying 'don't destroy the heavens' as a response to how powerful his form is there is no confirmation he is going to passively destroy the entirity of Valhala, if Shiva can burn it all like the OP said on a whim he wouldn't be making a comment like that if he scaled anywhere close casually or otherwise logically cause after all. Zeus even has a really funny other name;
Jehovah and God Father of the Cosmos.. must we scale him to his epithets too?
4)Shiva CAN NOT destroy and recreate the world on the whim, he uses a technique called the Tandava Karma, which takes time to burn everything up if we assume it to be true however we've seen legends be wrong before (Thor's 100% hit and his gloves for quick examples).
and for the examples of these legends being... wrong:
-if anything Shiva is doing this with more just an over time or through environmental destruction feat it does not scale to his base AP nor to other gods base as Planetary / Large Planetary
5)We have no time frame on how long it took to destroy half of Helhiem it looks like a standard portrayal of 'they raised the city in a savage plundering' we see in media the closest frame is that it was over night and he was gone in the next morning meaning he was there for a part of the night and again this is another Legends piece which we've established can be wrong (RoR's Prose Edda again)
I am fine if the series wants to actually give us a feat of them being planetary or large planetary with more context but as it sits Record of Ragnarok with full context of the story does not really have that sort of capacity, after all... Chaos is one of the strongest attacks in the series and is a single attack with the hype line reading "it threatens to swallow the heavens" oh wait.. yeah that is right a single attack over time... hmm another case of maybe ED via Technique?
No, it is not because he has a limit: We know Beel gets hurt from the technique and he also cannot end his own life given Satan's existence... so sounds like he would never have swallowed up the heavens anyway and we have no way of assessing the level it got to before it stopped previously in Helhiem at its maximum anyway as it is off screen
IF anything it isn't that Thor's feat of off screening Jormangand should be taken as bad it is noted inside the series as impressive, we have to still ask "sure it was a single hit, but how much damage and how did Thor strike the big snake" which we have zero confirmation how he killed it save 'it was 1 strike' RoR's big snake could after all have had a weak spot, it could have been smaller and we only have a singular comment of it being called the World Serpent without ANYTHING else for its size, that isn't vague that literally is a single mention of its title in the two times it was mentioned. The justifications for Planetary and Large Planetary is not enough given prescedent shown in other series and
we are being too generous to RoR and its Attack Potency much like we were with speed before the Apollo fight. To quote the Attack Potency page and Statements page,
We do not have enough information to say these guys are at those Tiers given the lack of a single attack scaling there, there being issues with the assumption of the big snake Jormangand with no confirmation on its size, there are a slew of issues with the original posters other points as presented between this and my previous post on this thread.
If this series has is enough to justify Planetary or Large Planetary, there is work to be done for other series upgrades who have this level or greater of proof for their canon. With this I stay my hand and wish for the people who can approve this to consider my efforts in explaining why it doesn't fit the range.
