" He is a goofYes, yes he is lol.
Yeah Apu caught him by surprise too. Now if he is caught by surprise with someone who has haki sure but since no one in naruto does it is up to other jutsu and genjutsu.Ok, even ignoring that Chakra may work similar to haki (both are energies that can be infused into weapons, as seen on Amazon Lily) Something like the ethereal sword of Totsuka would work. Once Kizaru materializes he falls to below lightspeed, and in that form Itachi has the reaction time to put up Susanoo (as seen with Kurin) and use said sword, putting him out of commission for eternity. Not to mention a genjutsu as well, which Itachi can even cast with his finger.
Apu looked up and notice the light when Kizaru kicks down? the same thing with the first guy it is simply slowed for out convienience.Yes, he can travel as light with Yata no Kagami, then he must materialize, he has done this every time. When he blitzed Hawkins he materialized right in front of his face, Hawkins simply lacked the reaction time to do anything about it. Kizaru can turn his foot into light for a kick, but his body is still materialized and thus not light speed.
. Not to mention he shot that light speed laser at the guy while solid. "Thats true but that seems to be one of his weaker attacks (he's never really used it to finished anyone, he used it to blind someone though), his stronger ones involve him getting in close.
