1. In the process doesn't mean completely dusted. Her body still had shape.
2. Even a casual punch from Saitama would absolutely obliterate her. 7-B vs High 6-A? That's an absolutely massive gap, and he vaporized far more potent foes with just one punch.
3. Her determination in the given scenario is certainly not as high as in the Genocide Run- even if it was, she'd still get one-shot.
4. She won't have time to know he was a strong foe since... She'd be dead.
If you really want to argue that she has Mid-High or High Regen, make a CRT. But she doesn't. Even in the Genocide run, her body still had a semi-consistent shape and wasn't completely gone. And that was with far more determination than she'd have here.
Until you can prove she has High Regenerationn in a CRT, your vote can not be counted, since your entire argument relies on her having High Regenerationn.
1. Her having shape was the particles of her body being held together, her body had still separated regardless and thus qualifies for that level of regen.
2. See Mosquito Girl only being pasted to a blood spatter, not fully obliterated, see Vaccine Man, Deep Sea King, etc. (All within Undyne's range, mind you)
3. It does not need to be, as I've already stated it was still enough to her to persist beyond death and hold herself together.
4. Pointless statement. See above.
She was on the verge of bursting, her body had been reduced to particles as the visual in-game was clearly trying to represent, if she was able to hold shape and reform based on this it qualifies for that level of regen.
"And that was with far more determination" Not really? In both interactions with her she starts off by feeling defeated, but only afterwards continues to fight on. In fact, she seems more angry and motivated to not die in the Neutral route, in which she still fights as she's splitting apart and reforms with enough determination to mush herself.
She performs her reforming feat in Genocide prior to mustering up the Determination to become Undying, which happens during her monologue. Undying only comes into fruition with the stakes presented, as in Neutral it was about everyone in the Underground, in Genocide it was about Earth.
You haven't exactly presented an argument that holds water to the idea she doesn't have Mid-High. Being split into dust is still just that, regardless of her using her determination to retain her shape and regenerate. So I see no reason my vote should be discounted.
It should be pointed out that Undyne has Regen on her page as well, but the degree is unspecified.
