I'm gonna start by saying that most of what Kojiro has is from
his skills long surpassing human limitatio. Now, of course, on its own this would be impressive but meaningless, however, in the context of fate, he scales above all of the skilled warriors and mages in all of the Nasuverse. I'm gonna be trying to match your points beat for beat with feats from the nasuverse, but where I can't, I'll put in other impressive feats. Some of these will be recycled from the Musashi vs Ikki thread, just a heads up.
Cool, Kojiro's mentality and fighting style allows him to f
ight in such a way that an enemy will never be able to get used to his attacks/techniques no matter how many times they percieve or analyze them, and this includes analytical precog users and the many skilled swordsman in fate. As for animal arts, one of the people who Kojiro scales up from is
Rider (Red Hare) who has mastered every single martial art there is. No matter what situation you put him in, whether that be the vacuum of space, under water, etc. he will still have a martial art to respond to it.
One of the people Kojiro scales above is
Lancelot, as user of Eternal Arms Mastery. Now, Lancelot has a bunch of really good skill feats, and if the sword saints weren't a thing, he would be one of the ones I would be nominating for a most skilled list, so expect to see a lot more from him thoughout this lol. Out of his many skill feats, he was able to keep up with Numeral of the Saint amped Gawain despite a massive stat difference on his own. There is also
Lancer Purgatorio, who's Eleven stances are such an absolute defense, that they can block attacks from
Saver. Here's a little more on Hozoin, which I wrote about in a previous thread:
- Someone else who Kojiro/Musashi naturally surpass as they have surpassed the bounds of human limitations, is Hozoin. The Lancer of Purgatorio who's noble phantasm, which is just his raw skill and technique btw, is able to cope and repel any technique or attack he encounters within the Nasuverse (obviously he isn't gonna be repelling the incineration of humanity from Goetia, but almost anything else is up for grabs), including basically any of the wierd ass weapons, most OP forms of magecraft, and extensive techniques, he can repel and then immediately follow with a counter attack. Oh btw, it doesn't matter if he has never seen it before. Geronimo's AoE Scorch the Earth Sun Magecraft? Nada. Billy the Kid's ability to slow down time to the point that he will always have time to respond to an enemies attack and line up a shot with time to spare? Gone. The Zabaniya techniques of the Hassan (You can find basically all of them on False Assassi's page)? No good.
Sorry for being so long-winded, but I hope this can successfully respond to the various blocks of Poseiden's attacks from your Kojiro, as well as his thousand image defenses
Yagyu (who just to be clear, is only slightly worse than them, and right on the cusp of surpassing human limitation himself) has a
technique that is capable of accounting for all possible outcomes of a situation, and staying a step ahead of all of them. It is so absolute that Musashi had to create a completely new possibility to manage to bypass this technique.
The power copying is impressive. Here's some good stuff from fate on that. Users of Eternal Arms Mastery, such as Lancelot, gain that ability from surpassing the skills of everyone else in their era. This includes Imperial Privilege users, who (depending on the level of the given user) can gain any martial art or skill set they want on a whim. Some of them need a basis to gain a new skill, some of them don't. One of the most notable Imperial Privilege users is Cleopatra, who is a servant so weak that she isn't even supposed to be able to engage in direct combat with other combat applicable servants, but her with her use of IP she can now keep up with most of the Knight Class servants (Sabers, Archers, Lancers, etc. all legendary folks of their craft).
As kind of a counter to Power Copying, Okada Izo the Manslayer, is capable of copying any sword technique or noble phantasm. Of course, there are limitations on this, but they aren't crazy. The techniques have to be Anti-Unit (meaning, he can't copy a tactical nuke or anything like that lol), and they can't be relient on the nature of the weapon itself (meaning, he can't copy Siegfried's Balmung because the release of True Ether comes from the blade itself). Anything other than that is fair game, but even he cannot copy the mystic sword techniques of Musashi or Kojiro.
Before I stop, I'm gonna toss this description I wrote before about some of Lancelot's abilities before in here, so you can get an idea of him:
- Eternal Arms Mastery users have reached such a state of mastery that their Mind, Body, and Technique/Skill have perfectly merged, and their technique has been ingrained into every facet of their body. Even when insane to the point of not being able to form a proper thought, they can still fight just as well as if they had a clear mind. You could give them all the mental illnesses you can think of and it wouldn't interfere with their combat at all. Lancelot (one of the EAM users) is so skilled that he gained the ability to pick up basically any object that he views as a weapon and use it as if he had trained with it his whole life. His Noble Phantasm, A Knight Does Not Die with Empty Hands, which was sublimated from this allows him to enhance them to the level of a D-rank Noble Phantasm and even allows him to sieze weapons from he enemies, and although the latter two effects are obviously more effects that came with the legend, the ability to use these weapons effectively is all his skill. He could pick up a stappler, chopsticks, a rubber band, a pair of glasses, a tree branch, Guns (keep in mind, he's a knight from medivel times), a fighter jet, etc. and use all of them perfectly for combat.
