This is how I think the matches would go with Deku
Deku Vs. Ruby Rose
So Deku has some big advantages right off the start, has better flight than Ruby, and he can out range badly her Sniper only goes to hundreds of meters and Deku using OFA has range up to tens of kilometers. Deku already has experienced in dealing with sniper shots since he fought Lady Nagant the best sniper across the country and Ruby doesn't even come close in skill compared to what Nagant can do. She can fire curved bullets from kilometers away and that's with pure skill and combined with Danger Sense, Deku has no problem dodging any of these shots from her. If she gets bind with black whip, the fight is over, Class T Vs. Class M the only thing that could pose a problem for Deku is dealing with her intangibility, but Deku could easily come up with a plan to counter it. Also with Fa Jin he can blitz Ruby and if he decides to use it for offense Fa Jin + 45% can break the bones of people comparable to him and since AP is equal Ruby will take serious damage if she gets it buy it with all these advantages on Deku's side, he should win this with little to mid-difficulty.
Deku Vs. Senku
I don't think any explanation is needed for how badly Deku will fold Senku all he needs is black whip and the fight is over lol Deku wins with negative difficulty
Deku Vs. Asta
Already explained how Deku would pull off a win against Asta, so I'll just paste it here since it's basically the same rules and settings and since Fa Jin is available Deku gets even more chances to win
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. Goku
Fight begins and Deku gets thrown into the sun lmao against Goku he has ZERO chance against him self-explanatory
Deku Vs. Byleth
So this match was already done officially and Deku won with mid-difficulty, the only reason it got removed is that Byleth got downgrades to 7-C is his Base key so nothing really changes
Deku Vs. Red
I'm not that knowledge on Pokémon, so I can't really say how the fight would go, but looking at the profiles, Red does have a good amount of hax that can put down Deku. So if no one can argue this match, I'll just give the fight to Red
Deku Vs. Legionis
So Deku has superior skill compared to Legionis and can out range since her highest range only goes up to hundreds of meters while Deku has tens of kilometers she can easily bind her, and she won't be able to break out since she is only Class M the only thing I see that could pose a problem for Deku is her Invisibility, Paralysis Inducement, Absorption. Invisibility shouldn't be a problem thanks to danger sense and I don't think she can absorb air blasts from Deku and only one legion can be active at one time, so Deku should be able to counter easily and plan out this fight, leading him to a low victory win. Maybe mid-diff
Deku Vs. Rick Sanchez
If Rick has prep time then he stomps Deku badly he has way too many ways of taking Deku done not to mention his IQ is on another level compared to Deku's if Rick doesn't have any prep I'd still give it to Rick, I don't think I need to explain the amount of hax that rick has and Deku's only win con is binding with black whip, but it's unlikely since Rick has so many options available and that is his only win con so Rick stomps and dog walks in every other scenario I'd say he wins this fight with negative to no difficulty
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. So Ichigo wins with little to no difficulty
Deku Vs. Jotaro
This match was already done officially and Deku got stomped or Jotaro won with little difficulty it was a long time ago, but I doubt anything Deku has gained now changes the fight, so another L for Deku
Deku Vs. Saitama
Self Explanatory Saitama stomped Cosmic Garou with one hand and Deku Vs Garou was already done and Deku got stomped and that was Human Garou not even Half Monster form so yet again Deku gets bullied
Deku Vs. Sonic The Hedgehog
So game sonic is being used her and not Archie but still Deku has no chance here Sonic can overwhelm him with his wall of hax, and all he really needs is BFR and Deku is gone also not to mention Deku only has like 2 to 3 resistances in total anything Deku does get easily counter and Sonic sets up his next move with Dura nega, teleportation, time stop there are too many options he has available so Deku gets folded like those cheap chairs on WWE
Deku Vs. Luke Skywalker
Not much to explain here it's a skill and hax stomp in Luke's favor Deku can't win
Deku Vs. Ben 10
Alien X gg ez
Deku Vs. Nastu
This match was already done officially and Nastu won with little difficulty and now that Nastu is in his strongest key Deku stands no chance he gets turned into Katsu Pork
Deku Vs. Henry Stickman
How does a ******* stick have so many hax wtf Deku lost again lol
Deku Vs. The Imposter
Bruh Deku skill stomps and basically just stomps in general
Deku Vs. Inklings
So the Inklings have Mid-High regen which makes this a stomp for them even if Deku binds with black whip then can just go intangible and reset the fight
Deku Vs. Steve (Minecraft)
So Deku takes this with little difficulty there is not any potion or piece of equipment that would take Deku, especially since Deku just skill stomps the only potion that could pose a threat is Decay which is basically like Shigiraki's decay so if Deku gets hit by that he is done for but throwing the potion can be easily picked up with his danger sense and prediction plus the range is only tens of meters at best. Deku can also out range and the Elytra doesn't have true flight unless he has fireworks which I'll just assume he has but that changes nothing. If Steve has the totem of undying he can revive once but Deku would just easily kill him again, or he can just bind with black whip, plus if he dies all of his items will drop. Any potion he tries to drink would take too much time, and Deku wouldn't allow his opponent to get stronger. So yea, I don't see Steve winning this at all.
Deku Vs. Gingka Hagane
I still can't believe a metal spinning top is uni+ but nonetheless Deku can't do anything about Reality Warp or BFR, so he gets stomped
This match was already done and Johnny won, so nothing else can be said here
