Lock i really not gonna bother explaining why he will be able to block it because it seems that you are confusing that the reason why he can't defend agains't the attack its because of durability when in fact its not, killerbee was in pain when he was hit with amaterasu despite the fact that his body is more durable then v1 kyubi cloack what matters its that what amaterasu went in contact with is energy and the other is not. And that what NE is an invisible Phisical energy.
Even if you keep denying that doesn't matter naruto can still dodge it using frog kumite his feat of dodging the raikage support this and no you have zero statements proving that ay is faster by tha way.
Durability is important because even if we give Naruto the imaginary ability, the flames would burn through it and reach Naruto just like it did to Ay's lightning armour, I'm giving this fanfic way too much attention and you should be ashamed of actually wasting my time with it.
How is dodging Raikage make his movement speed comparable to any of them? That's a reaction speed feat not a movement speed feat.
Ay dodged Amaterasu by leaving Sasuke's line of sight, Sasuke can't track Ay's speed in V2, who's faster by feats but ignoring that, Naruto still doesn't have the movment speed that puts him on the same league as V2 Ay's shunshin, don't confuse movment with reaction speed since both are very different.
And thus Naruto can't dodge it unless he can move faster than Sasuke's MS can track, which he can't unless you have feats of SM Naruto being cabable of doing so.
