Oni vs. Nemesis

Modern nem would ruin the Oni. I bet he could pick the oni up with one hand just like the survivors. Keep in mind that Nem is shrunk down in dbd.

Nemesis bruh. He has a Hulk form. XD Look at that big #########!

From a DbD perspective, Oni is clearly more dangerous. Nemesis' tentacle strike doesn't even inflict damage on first hit, it only infects the victim - with a mild cough... And from there it only deals 1 health state damage. Oni's demon strike not only inflicts 2 health states damage instantly, but it can in theory even inflict 8 (or more), if people line up or run into it while it lasts. His kanabo has much more destructive force than Nem's tentacle in DbD. Oni is also much faster.

Oni does need to draw blood to get access to his powers, but not only does that seem easy enough to do given that he can slash Nem's arms during punches or tentacle during strikes, but there's also those zombies with him, which are easy targets for Oni to slice and fuel up on blood from.

Pitting him against RE Nemesis would be more interesting, but ultimately Nemesis is merely biological, whereas Oni is supernatural - rather than being brought back from the dead with science/a virus, he's an undead spirit, a sort of demonic force propelling a body that should already be dead. There's a cosmetic showing him with serious wounds all over his body, and yet he's still as fast and strong as usual. So we have to assume he would be able to keep fighting fiercely even in drastic stages of being injured, and who knows, maybe this demonic force could even achieve what Rin, his relative, did: be able to keep moving limbs even after they're severed.

I agree with the well written take from @TheRockstarKnight both of them can win it depends on what factors we take into account etc.

But if we're talking about DBD lore wise Nemesis got really nerfed compared his to RE counterpart which is fine of course because he can still deal with most of the killer roster easily.

Oni lore wise might be in the top 3 most powerful killers right behind Cenobite and Pyramid Head.

Like tell me what's Nemesis(DBD lore wise don't forget)gonna do against a Japanese demon rushing at him full speed with his Kanabo about to blow his head up,whip him with his pathetic tentacle ?

Oni might even be stronger than Nemesis in term of raw strength especially while in Blood Fury and don't forget that Kazan is a experienced warlord true he never fought against some creature like Nemesis before but I am sure he'll manage and eliminate him quickly.

So yes in this case if we talk about DBD's Nemesis against Oni,Kazan will get the W and it wont be even close.

RE's Nemesis would completely murder him tho and the whole killer roster included.

Isn't good ol Micheal Myers also up there for the top 3? Being the whole incarnation of evil itself and more powerful than, or at the very least equal to the entity.

You even specifically quoted me saying "From a DbD perspective", and then you talk about regeneration and rocket launchers. Again, from a DbD perspective Oni is stronger since his attack deals much more damage. Nemesis' raw muscle strength is at best equal to Oni in DbD - both deal 1 health state damage on basic attacks, both take the same time to break pallets/walls at base and can destroy them in 1 hit with their abilities, they also take the same time to pick survivors up, carry and hook them, and both get stunned by pallets for the same duration and move at the same base speed. While these are obvious, it's not like BHVR is unable to adjust base stats like this for different killers (and particularly for Nemesis I had actually hoped they would do so, at the very least with increasing "mutation" tiers, to do justice to how much physically stronger he should indeed be expected to be compared to most other killers).

And yeah, once in Fury, Oni is propelled by some supernatural, demonic force that not only gives him objectively more powerful characteristics than anything Nemesis can do in DbD, but again, even when facing RE Nemesis I would not write Oni off due to this. It could be entirely possible and plausible given his backstory that Oni is essentially immortal, since even after being tortured to death and beyond, he came back to haunt the lands, stronger than before despite his wrecked body. Like with Spirit, it's even possible that being a demon, he isn't even strictly bound to his body and can move limbs even after they've become detached, which would of course go to show that physical strength in the sense of muscles, tendons, joints loses most of any meaning, and it's a magical strength.

My main angle with my post was honestly more of a "Nemesis is completely neutered in DbD and a shadow of his menacing self from the originals", but even if I were to take the premise of the topic more seriously in a general sense and ignore what has already been said about that being more or less impossible given that these are entirely fictional entities, I would not see as much of an imbalance there. Of course Nemesis at latest in his mutated forms appears like he should be able to toy with Oni, but I mean, freaking Jill killed Nemesis, and survived encounter after encounter against him, including of course all the mutated forms. While this would probably entail Oni using firearms (lol), at the very least we can say that if Jill is able to consistently dodge/survive Nemesis' attacks (including the rocket launcher), then Oni certainly should be too, given that he can achieve superhuman speed and has a superhuman ability to endure.
