This is how I think the matches would go with Deku
Deku Vs. Goku
Deku has Class T and Goku is only Class M he can bind with blackwhip and wail on him gg nah but seriously tho Deku gets stomped badly self-explanatory
Deku Vs. Naruto
Naruto can out hax and out range badly everything Deku throws at Naruto gets countered and in CQC Deku stands no chance he can also use the TSB and just erase Deku his Pre cog and other ways of sensing the opponent's attacks and moves are on another league compared to what Deku can do. Also, not to mention Naruto is invulnerable and can't be hurt by normal attacks, only Senjustu. Deku gets stomped again
Deku Vs. Ichigo
Deku has flight and can out range Ichigo unless he is using the Getsuga Tenshō, but that means nothing when Ichigo out skills and has multiple ways of sensing attacks and countering Deku. Ichigo also has regen which makes the match even harder for Deku. Black whip gets easily counter, and he can cut through it like butter even if Deku does bind him he can easily break out since his LS is superior to Deku's. Deku could avoid a couple of attacks thanks to Danger Sense, but Ichigo is too relentless for him. Smoke screen worthless since Ichigo can just sense him, and he can counter Deku's flight with his own. Since AP and Speed amps are not allowed, Deku does not have access to Fa Jin, which takes a good blow in his arsenal. So Ichigo wins with little to no difficulty
Deku Vs. Luffy
Unfortunately for Deku, this is another stomp match. Luffy’s range, stamina, hax and LS all out class anything Deku can throw out. Especially since Luffy can resist Blunt Force damage and this is Deku's only method of attacking. Deku gets dog walked flipped tossed put on a skillet, you name it, he stands no chance.
Deku Vs. Meli
So Meli has Passive
Status Effect Inducement,
Disease Manipulation,
Mind Manipulation and
Corrosion Inducement all things that Deku can not counter expect Mind Manipulation, but that doesn't matter any way so Deku gets stomped once more
Deku Vs. Nastu
This match was already done officially and Nastu won with little difficulty, putting Nastu in his strongest key just makes things worst for Deku. 2 million degree does wonders for you, so yet again Deku gets stomped
Deku Vs. Denji
Deku can range spam from far away and if Denji gets bind with black whip the fight is over. Deku's skill surpasses Denji's and can dodge any of his strikes using Danger Sense the only thing that could be a problem for Deku would be Denji's regen, he can regenerate from just his heart alone, but there is not much else that Denji can do against Deku. Especially since Denji is using chain saws and Deku won't fight up close against an opponent with bladed weapons when he has flight and range at his disposal. So Deku wins with little to no difficulty
Deku Vs. Asta
I believe this is a close fight, if energies are equal then Asta would win with no difficulty, but if they are not then Deku should pull off a win here. The only thing Asta has available to use is Ki and Range Anti-Magic slashes, most of his arsenal is useless. Deku can counter his pre cog with his own, and he can use Air Force to counter the anti-magic slashes. It comes down to LS and skill and Asta LS is superior to Deku's so Black whip won't work and clashing with Asta is only going to hurt Deku and Asta going by their profiles and what I've read and watched Asta has the upper hand here but not to a point where he gets skill stomped or out skilled. So Deku has range, can counter Asta's pre cog and can predict Asta's moves thanks to his Analytical Prediction which he can predict the moves of opponents that can out pace him in combat speed and can create after images to confuse Asta. Deku should be able to take a victory with High difficulty
Deku Vs. Yuji
Alright, I think it's safe to say that Deku is superior to Yuji in skill Yuji is very gifted and is quick to set up his next move but Deku skill's against Lady Nagant does not compare to anything Yuji has fought. Deku can dodge any attack with Danger Sense when it comes to range Yuji is shit out of luck Deku has range up to Tens of Kilometers with OFA and Black whip and smokescreen has hundreds of meters in range and Yuji only has standard melee range there is not much he can do. If he gets caught in Black whip, the fight is over and the only thing Yuji can kill Deku with is his Soul Manipulation he can damage the soul with his fists, and it might be a one shot, but it won't happen due to range, flight and danger sense from Deku. So Yuji stands no chance here, so Deku takes this with no difficulty
Deku Vs. Tanjiro
Deku skill stomps badly, Tanjiro in this state is borderline stupid and isn't even aware of what is going on and only attacks and screams at whatever he can see. Deku counters Tanjiro's whip attacks with his own whip and can just bind Tanjiro and the fight is over. I don't think I need to go into detail about how this fight would go, except two things. In this state Tanjiro has Muzan's blood which is infused in his attacks, so if Deku gets hit by any of these at any point his body will begin rapid mutation causing cellular destruction and quick melting and vaporization of his body. But can we say that Tanjiro can do the same thing here? Is it passive or an instinct thing? Not sure on that because that could change the way this fight goes. A single scratch would be deadly, but Deku could catch the whips with his own and bind Tanjiro. Another thing is Tanjiro's regen which is High-Mid which is another problem for Deku but if Tanjiro has no solid parts of his body remaining he can't regenerate so Deku would have to rely on this method or just bind Tanjiro. So in the end Deku should win this with little to mid-difficulty.
Deku Vs. Perry
Bruh if your favorite characters can't beat Perry, rethink life, don't even need to explain this fight lol
So 5 Wins and 6 losses for Deku not bad
