Don't expect me to contribute much.
The obvious thing is that Ketheric's abilities operate on a 4-D scale. I state this now, and presume that Naruto also has that. If it doesn't, then problems arise. Given that Ketheric isn't actually a hax god, I don't think this would intrinsically make this a stomp (although any of Madara's hax would not work on Ketheric, given his wide range of resistances- it would need to be very niche indeed, or be 4-D and layered significantly).
How good is Kethrics immortality exactly? Could he survive getting smashed into a paste by a Susano? I'm not knowledgeable about DND lore or scaling, but from what I remember from the game he never had any super impressive feats for his immortality.
Also, it would be worth noting that Madaras Genjustu's mind manip is layered while Kethric's resistance is not.
He doesn't have Mid-Godly, he has immortality stolen from a being that has Mid-Godly. As long as that creature lives, and is within the Soul Cage created for it in the Shadowfell, Ketheric will rise again, wounds vanished. As said, this is because it is stolen from this divine being (Dame Aylin), so being smashed to pieces would obviously not really be a problem- Mid-Godly being what it is. To your later point ("it should be on the profile")... eh. It isn't now, because technically he doesn't have it, but I can see the point. It could probably be added.
Because you seem knowledgeable about the game, at least, I will elaborate on Dame Aylin, since you acknowledge you're not familiar with D&D and what all that would entail. Dame Aylin is what would be known as a "quasi-deity"- the direct child of a deity carries in themselves a Divine Shard, functionally rendering them a Deity with a Divine Rank of 0. This extends a range of abilities to the creature, but the one we're most interested in is the Mid-Godly regeneration that any creature with a Divine Rank enjoys.
He doesn't have godly regen in this key on his profile. I feel like that should be included in his profile if he has that.
Going off what you said I'm assuming that if magic in general is 4-D in DND, then Madara would be screwed if Kethric hits any soul hax on him. Madara's precog and speed amps should be useful here as from what I can see Kethric has to actually hit Madara to use his soul manipulation. Susanno would be pretty useful for this also since it's essentially a big forcefield made of chakra.
I'm leaning toward Madara rn as it seems like Kethric has to land a Smite (which to my knowledge is a melee spell) to kill him and as soon as Madara enters his Susano that essentially becomes impossible for him since Madara's susaano is huge and has a higher durability than Kethrics AP. Madara on the other hand, can just seal Kethric in a chibaku tensei.
Ketheric's soul hax isn't an instant kill. It's a bit complicated, because D&D is first and foremost a game- but the damage Ketheric deals is to the soul, but it is not something that immediately annihilates it. Generally speaking it should be viewed as a way to bypass traditional durability and to damage souls for those who require it- it does kill targets faster than without, but it's not a trump card, one feels.
Sealing wouldn't work unless it was greater than Ketheric's 4-D resistance to it. It's far from comprehensive but currently accepted general resistances of D&D can be found
here. Anything listed here, Ketheric resists on a 4-D level. Again, I don't know much about Naruto, so it's plausible this match was made with that in mind, in which case we get to discuss layers. Otherwise, Ketheric can't be touched by these abilities.
I don’t recall ketheric using energy beyond the netherese stone, and even then that’s specific to the whole elder brain control. He might use it with his oathbreaker powers but I’m not sure how it meshes with Preta.
Divine smites have variously been considered energy depending on the description, although the more consistent representation is that the attack is simply blessed. I would suggest his force attacks are most certainly energy (albeit made of magic, I will assume verse equalization covers this).
Now, my suggestion outside of responses. Ketheric isn't a particularly flashy fighter in the context of this wiki. His main shtick is that he will attack people in melee for huge amounts of damage via divine smites, and he will attack often. At a range he tends to prefer the aforementioned force attack. It's worth noting that Ketheric transforms into the Apostle of Myrkul by right of being his Chosen- this introduces a number of complications, among them that the Apostle of Myrkul is abstract in its physiology, which can make fights essentially impossible should his opponent be unable to hit him.
Incapacitation aside, killing Ketheric Thorm requires two extraordinary caveats to be fulfilled over the usual:
- Dame Aylin must be freed from her Soul Cage. Killing her is also acceptable. While she is typically Low 6-B just as Ketheric is, she is extremely weakened while within the Soul Cage, and does not have access to her abilities; it would be a fairly easy task to kill her or free her, provided one could reach her within the Shadowfell.
- The Apostle of Myrkul must be destroyed following Ketheric's first "death".
It is not my intent to contribute to this match much, for what I hope are obvious reasons. I aim to clarify and little more.
