He didn’t have 4 of the 6 quirks in OFA the first time he fought Shigaraki. What he had was no where near the full power of OFA. So I don’t see how he’s a “liar” if he’s gotten better at mastering ALL of them and has none left to awaken.
His percentage has 100% gotten better, his body is stronger, his skill is higher, he has all the quirks he should have. Time doesn’t care about whether he thinks he’s ready or not. I’m simply saying that regardless of what he believes, he has the tools to perform far better against Shigaraki than last time, who so far has shown no noticeable improvements physically, though he does seem to have better quirks.
If he’s stuck at the same way he was in the war, then yes, he’s ******, but he’s literally been training TO unlock OFA’s full power. So him being more prepared now doesn’t make him a liar, especially when “OFA’s full power” is vague and either alludes to having all the quirks or using 100% with no problem. The first one he has, the second he doesn’t have the time to get.
The biggest issue for Deku is regeneration from Shigaraki. If he gets some way to stop his regeneration, Shigaraki is ****** and gonna wind up like he did when Aizawa entered the battlefield. None of his other quirks are helpful much if Deku can avoid most of them, and the strength difference isn’t going to be as high as it was.
Shigaraki’s best quality is surviving like a cockroach and then striking when people have tired out. That’s how he wins. He’s nowhere near as strong as 100%, or as fast, he just survives. It’s a matter of breaking through the regen, then he’s just dead or forced to overexert himself again.
And yes, Deku wanting to save him is going to matter a lot in the fight and probably help or damn him. I’m just stating that Shigaraki is overrated in a rematch unless he gets New Order. Without it, I’m saying it would be even, and at absolute worse, slightly tilted in Shiggy’s favor due to regen + variety.
Stats are not going to be the sole factor for their next fight like they were last time, I feel. So it’s going to come down to skill with quirks and how to get around your opponents advantages, of which I believe they are even. Shiggy tanks damage and regens, Deku avoids it all together or just deals with it. Far be it from me to predict how their fight is actually going to go, especially assuming Shigaraki gets New Order, but that’s just what I’m seeing currently. They are around each other’s level.
