How did Itachi even had a chance to defend himself?

[Dantee]

Proof

No proof needed for common sense.

Unless you have sharingan lol.

Sasuke wasn't going to stop the technique regardless of whether or not he saw Itachi activate something. And Itachi's Susano'o disintegrated upon impact with Kirin, so there was nothing to see after the Jutsu had been used - until, Itachi re-activated Susano'o.

50/50

I think he didn't activate it before impact but meanwhile

He took some damage and his akatsuki robe was teared

another itachi thread

most overrated anime character ever

who cares about a dead person anyway

stupid fanboys

 

[Frikid]

itachi have sharingan which can predict movements.
itachi knew sasuke gonna do something big, so he activated susano at that very moment.

 

[Gaara]

Itachi activated it before Sasuke sent the lightning down. Not to hard to understand.

This^
If your gonna stand there and tell them the whole plan before you do it. Saskue might aswell of been Dr. Evil lol
