> It took a loooooooong while and unlike the Colossal titan, Eren wasn't aiming to make it permanently hard. Not to mention he had to tank the entire force collapsing and protecting himself too. He's basically outstretched himself.
Why are why discussing this again? I hope you're not trying to argue that Eren could somehow catch Deku with his Hardening, because first he had never used his Hardening in that way, and second Deku could just simply dodge it.
> I saw some arguments and justification where Deku only improves his striking power/attack potency by his Quirk and still suffers from attacks tossed at him. If he gets hit his momentum can be slowed down and that won't spell well for him.
The first part is partially right, Deku's normal durability is already Building level+, Full Cowl doesn't increase his durability as far as I know, but if Deku suffered from attacks tossed at him, then those attacks should be Building level+, anyway I don't remember something like that happening in the manga.
About his 20%, I was talking about when
Fusion Chisaki tries to attack Deku, the latter dodge the attack and then jump several meters away,
while Chisaki is still looking down where Deku was before.
So my point still stands, Deku doesn't need 20% to keep his distance with Eren while attacking him with Building level+ air bullets from a safe distance, and the air bullets are even hard to dodge for people like Gentle who is faster than Deku himself, Eren can throw chunks of buildings yes, but their are not going to be faster than the speed of sound like the Beast Titan's throws, which means that Deku can easily dodge them, and even if they were at that speed they can't still harm Deku since they can't generate Building level+ energy, there is a reason why he never throw things to Titans comparable to him like Annie or Reiner, it's simply useless unless your name is the Beast Titan.
