My man there was a 700 Megaton cap for a reason, if you're going to say that his actual basic punches are stronger (they are) than these AoE screen clear level punches that cant be avoided, why is All Might even here, or any MHA character if that's the case? He'll just AP stomp everyone.
All Might is always at 100% thats kinda like is whole thing and we accept that his punches are much stronger than his air pressure. his Air Pressure is 784 and has been shown more times to match other characters in that level like All For One's air cannon quirk. the times the air pressure is weaker are times when All Might is explicitly stated to be holding back like against Deku and Bakugo.
Which gives Kaizo an advantage over him due to his cunning and would purposely draw out the fight to the point all might is too weak to become a threat to him.
just because Kaizo is cunning doesn't mean he'll suddenly have prior knowledge on All Might and know he needs to draw the fight out against him, he has no clue about the 3 hr time limit that All Might has also All Might doesn't get any weaker the less time he has, we've seen him fight at peak condition with only like 3 minutes left against the USJ Nomu and even after being extremely weakened still fought against All For One.
That's not the point. the issue is All Might's shockwaves never really affect anyone that's gonna underground most of his instances involve clearing out the sky but rarely affect the ground and when it comes to CQC Kaizo could dodge his punches fairly easily by spamming teleport without getting hit by the shockwaves as he had been able to avoid attacks that were very up close to hitting him without fail.
I never said they'd be effective against someone going underground, nothing is exactly stopping All Might from punching the ground and creating a massive creator if he knows his opponent is below him which is what happen after his United States of Smash against All For One. All Might's fought plenty of CQC fighters before, he could dodge plenty of Kaizo's attacks as well, TP is obviously an advantage but it'll only delay All Might getting the necessary hits in.
Same could be said for Kaizo's barriers whom a 6-C only broke through only one out of the 3 with a twin punch once multilayered. so Kaizo's multilayer barrier wouldn't break from a single punch and requires more than a single smash to do so for each barrier
said 6-C was one tapping the barriers and even did so shortly after with a
single punch (12:49), just because he did so once with a twin punch doesn't mean his barriers are suddenly able to withstand 6-C strikes cause thats not what is being shown. All Might should be more than able to break through them even if it'll take a solid minute and we've seen him get launched right after his barrier was broken leaving his staggered, more than enough time for All Might to do something with.
Kaizo is pretty much a cqc fighter as well but he mostly has the greater quickdraw between the 2.
what does being a greater quickdraw have to do with anything? speed is equalized so no one is quicker than the other.
I'm still sticking with All Might, Kaizo's only reliable way of winning would be drawing the battle out but because he has no prior knowledge on All Might then he wouldn't know to draw out the battle OR the 3 hr time limit, just because he's cunning and intelligent doesn't suddenly give him information analysis on an opponent that would be like me saying All Might can counter his TP cause he's smart enough to know where he'd land (which given his enhanced senses and might sense that might not be completely impossible).
