But in this case, it was a one on one against Irene, it wasn't exactly a multi directional attack you know.
Acnologia aimed his attack at Irene and her alone, and she dodged it quite handily.
That's basically the case here.
It's debatable whether he was serious or not (I think he was slowly warming up to the fight personally), but the point is, Irene reacted to an attack that most mages couldn't react to, so that's a pretty notable feat
Personally, I don't see how a 1 on 1 makes a difference. Acnologia wasn't aiming to kill anybody.
Sure, Acnologia attacked in their
direction or
area, but that doesn't mean he was attacking
them.
In both cases, Acnologia allowed them enough time to get out of the way, to show his true power, but he didn't have any intention on killing them.
If he wanted to kill them, all he had to do was treat them like God Serena.
Acnologia was never serious with anybody. Not Makarov, not Tenrou Laxus, not Tenrou Gray, and not Irene.
Acnologia is on the levels of dragons, there is no way somebody from Alvarez or FT (at the moment) can dodge a single attack from Acnologia (whether that be magical or physical).
August is on Irene's level... and when Acnologia oneshotted God Serena within a fraction of a second, August was wide-eyed and sweating.
That tells us that Acnologia clearly still outclasses everybody in terms of strength, durability,
and speed. Nobody is dodging anything.
You brought up a point where you said "Irene reacted to an attack that most mages couldn't react to".
I never had anything against that statement. For all I care, that statement could potentially be true. You or anybody else here can hype that and Irene all you want. I'm not against that.
But to say that "
Irene dodged Acnologia's eruption" is a completely different statement...
I stick to my opinion and I honestly don't know why people recently don't see it that way.
There has always been a general consensus in the community that
anybody would be killed if Acnologia meant to aim his attack at them.
By the current feats, there is not a single human being alive in FT capable of dodging anything from Acnologia.
Acnologia is several tiers above Zeref, August, and Ishgar for a reason.
