Countless wars? Countless enemies? Galaxies? Who ******* cares.
None of that shit matters when it comes to skill. For all we know fighters across the galaxy are average or possibly even below average compared to earth's standards. Emphasizing the fact that countless battles happen across the galaxy doesn't do jack shit. We need more details on those battles and wars. We need feats.
For all we know the Vader's skill feats in the blog up there are enough to take down practically anyone in the galaxy. Not to mention Vader has too much power and hax compared to almost anyone. So yeah the only skills I recognize here in this match are what is in that blog and Theresia alone no diffs it with her own skill feats, and skill based abilities. She is the pinnacle of sworrdsmanship. She is so skilled that the most skilled swordsman below her thinks her skill can never be reached in a lifetime or eternity. Anyone who can correct imperfections in fighting styles can never match her in said fighting style meaning perfection is meaningless. That's how skilled she is.
Anything unknown to her will never work on her again after she sees it once. And I doubt there is shit unknown to her considering she knows and transcends all (except like 2-3 people above her) of the skill based abilities from vastly skilled swordsmen in that blog
@SatellaTheWoE sent.
Also she can use 6 arms with 6 swords on them thanks to Erza so uh... that enhances Theresia's skill with just one sword.
Concerning all these Force Shenanigans,
LS is equal so TK can be resisted in a general sense, as for the unconventional usages of TK, Neguna and Thereza are still fine via a multitude of ways especially via distraction or adaptation and so on.
Neguna would just heal any non lethal damage Thereza might get, infact the deer can use RCT on Theresia to heal missing body parts even lethal ones like the heart, while simultaneously disorienting Vader with shadow clones, sound based paralysis inducement (temporary), rendering the Force Sense useless with Mana Zone since its not layered (Nacht's mana zone turns the whole area into a silent pitch black and renders those with ESP+EH with the ability to sense life force and predict the future useless, while simultaneously attacking his opponents relentlessly from every direction; besides even if Vader sees the future all he will see is more darkness, he wouldn't even be able to see or hear his ass get beat). Thereza even has their own regen so all these dumb Force annoyances aren't a factor in this match anymore. Note: The only way to affect Nacht's shadow magic is to have NPI that affects things that don't physically exist (because Nacht is manipulating actual shadows and not some darkness magic shit in most fictions)
Also, Mahoraga would simply adapt to any lethal effects of the force after some time, its not like anyone can one shot it while simultaneously dealing with other shadow shinigamis of equal stats, shadow clones of equal stats, mana zone darkness, shadow arms, and Thereza (who can already defend herself with not just her skill and abilities but with the help of shinigamis healing her). So Vader's multitasking is good, but not THAT good. So Mahoraga is most definitely a wincon here and can counter annoying shit like Obito's Izanagi+regen+Kamui+TSO combo (he is most likely gonna counter regen by copying Sukuna ability to attack the soul, the effects of TSO can also be countered considering phenomenon exists in JJK similar to TSO's effects; Izanagi can't be spammed and its used defensively anyway and to cause someone to drop their guard, which isn't happening for Thereza thats for sure). Neguna doesn't even need to summon Mahoraga considering he just put his wheel on his back summoning is probably just better strategy wise.
Neguna has shit like damage reduction and can further amp themselves with more and more devil power, infact by combining devils their power massively increases. an increasein magic power leads to an increase in speed as well. On top of magic power boots, Nacht has a devil power called Felis Mode that boosts speeds to the point that he can dodge danmaku and massive attacks that litter the battlefield all from those already faster than him. Mana Zone is also a magic power amp that allows the user to manipulate the space around them thus allowing them to evade attacks mid air or at point blank range while also casting spells from any where in the space and at any direction making dodging quite literally impossible. Natch's mana zone has a special property to induce darkness in the whole area and ive told you how effective this is already. So Vader's rage amps or any other amps are taken care of.
Note: cursed energy is not negative emotion, its born from it. There's a difference. Not to mention Vader wouldve gotten cursed and ******* died if he tried to take in cursed energy.
Edit: You should probably check the restricted abilities for Obito... i dont think Izanagi can be used since thats Reality Warping
