The ambient energies of Nadd's spirit and his tomb. Lol, one of these entities might be helping him along. If it's the "energies of the tomb", we'll given that Kun is still a Jedi at this point and yet to turn to the dark side (force lsd, or a cheat to reach a higher level), we can probably say he's past the point where the Tomb amps his abilties as a Jedi beyond that of his final iteration as dark lord of the sith. This is especially true considering that Kun becomes the "darkest power in the galaxy" according to the same comic. Putting him above the energies of a tomb and probably serval other dark side organisations and worlds mentioned in the same comic.I see no reason to believe it wouldn't be both, given that even Darth Bane felt the energy of the dark side saturating Nadd's tomb millennia later, when it would have begun wearing off. And yes, it is heavily implied that Nadd, who has a history of amplifying the power of individuals in his spirit form (see Ommin and Amanoa), was the power "moving around him" that "wanted to help him."If it's Nadd who's helping him. Then there's two possibilities, either Nadd is unlocking some of Kun's own potential, which would happen when he turns to the dark side anyway. Or Nadd is giving him some of his own power, which is irrevant seen as Kun one shots him later, while still before his prime.
Kun with a nexus amp + Nadd's spirit actively empowering him (unlocking his potential is said nowhere), could well have been absorbed into his full power later on, but I find it important to note that he had a not inconsiderable amount of external power helping him during the feat.
If you're going to use this as a benchmark for comparing their power, why not use a more standard benchmark; their ability to destroy lightsaber-resistant weapons. As we saw, both Vodo's staff and Mighella's sword are lightsaber-proof materials. Vodo's is the result of him actively pouring energy into the weapon, meaning when Kun destroyed it, it was likely when Vodo was near the end of his reserves after receiving a thrashing both times. Whereas Maul was able to snap Mighella's perpetually lightsaber-proof weapon under the weight of his strikes after a brief clash. Add in Maul's own considerable feats like frequently tussling with larger-than-life monsters in strength contests, destroying durasteel droids with his strikes, casually deflecting Savage Opress' blows (which have hurled Dooku, something even Anakin has failed to achieve despite his own immense strength feats) and then bending his wrist out of shape, and decapitating a varactyl with his bare hands (the latter being without active Force augmentation), and I see no reason to suggest Kun is more powerful than Maul physically.
Not in any way that aids your forced comparison of what are Kun's most notable and distinct feats (which, no surprise, is why your argument seems to rest entirely on two feats which virtually nobody else has attempted and which are the only areas Kun could conceivably have an edge in, that is knocking down a Beskar wall and Force stunning non-Force sensitives - hardly compelling proof overall).
And again, by your own logic, legends are marred by embellishment and the like, so why not point out that such incredible feats as destroying a wall of Beskar are far from the truth?
If he can not maintain the same super-human levels of acrobatics as he did in his youth, then it implies that a large part of his fighting prowess is reliant on his own human physicality, which does indeed cheapen Maul. If someone like that presents a reasonable challenge to Maul, then the odds of finding people in others era's (particularly ones with more duelists) who can do the same is very very likely.I'm not aware of any grandiose acrobatics on Vodo's part, and given that Jinn would easily outduel many people who engage in the over the top acrobatics, like Aayla Secura for example, your argument seems to fall short. Just because someone doesn't expend unnecessary energy using acrobatics, it doesn't mean that of the energy they do choose to expend they are "cheapened as a fighter." It means that as far as Jinn's fighting style is concerned, his ability as a fighter stands on it's own. He frequently humbled Anoon Bondara, who engaged in plenty of acrobatics in the short time we saw him, so again, your argument makes little sense, however cunning it may have been. Jinn was just as fast and stronger than his much younger apprentice, Obi-Wan. Jinn has to conserve more energy because of his flagging stamina, but of the energy he does utilise, he still operates at a high level.
And let’s make it clear, not only was Maul thrashing Jinn on Tatooine, having him within one strike of death and totally exhausted within just 30 seconds, but when he was fighting the pair of Jedi, he did so comfortably, eclipsing both of their skill, leading them through the battlefield at his leisure, and was not even breathing hard by the end of it; so explain to me how this cheapens Maul as a fighter.
I think you can appreciate that there are many different ways we can compare Maul and Exar, different types of feats, accolades or any combination of them, but if you're just going to spend the entire debate trying to force comparisons on incredibly narrow areas that best suit Kun and worst suit the opposition, misrepresent information and make fallacious arguments for which I can only assume is pure sport, then I'm not sure I want to waste time on this debate. Ball's in your court, either way.
