@ohplease: About as fast as me putting on a bullet proof vest before someone shoots me. It doesnt make me a bullet timer. Only thing Itachi did was set up a Susano'o (wasnt visible yet and remained invisible until Itachi reveals how he survived as it was still protecting him). Even then, Itachi still got hit by the attack and admitted he had no othr way of surviving it, so he couldnt dodge or react to it.
@Whats_out_the_bag: Instance of them doing it? Remember it has to be actual lightning and not the chakra-made psuedo lightning.
Since when does a character actually have to lightning time to be faster lightning?
If you show speeds faster than it then yes you're faster than lightning. Also let's not forget itach reactinb to real lightning.
