You guys are all fools, this thread is pointless and is based on a bias intention to godmode kakashi. Kakashi was completely outmatched in both speed and strength by itachi and sasuke was able to do a MUCH better job than Kakashi was able to do against itachi in both dubbed and shipuuden, heck kakashi couldn't even keep up with a 30 percent power itachi clone, his speed and strength is no where near sasuke, nor is his mastery of the sharingan, even tobi hailed sasuke's use of the sharingan is something out of this world.
If you are going to introduce the raikiri, which is supposedly a superior attack to chidori, how about making A fully activate his raiton armour, or have you fools forgetten that the raiton armour that sasuke penetrated was not the full activated armour, he only fully activated his armour after that incident, when sasuke used sasuno'o to protect himself against A's liger bomb. And then what happened huh? Sasuke, who has demonstrated superior speed feats to kakashi was unable to see or even keep up with A's speed and forced to use sasuno'o and blaze release for defense.
Can raikiri penetrate A's armour? Maybe if you directly substitute him with sasuke at that scene. But what makes you think A would use the v1 raiton armour against the student of the only man to match his speed, he would obviously use the fully active version of his armour like he did after the liger bomb and kakashi would not even see him and die, his raikiri would be useless against the full vertsion that karin, the best sensor in the series analyzed as a jutsu that produces bijuu level chakra, raikiri won't work, sorry, kakashi godmoding attempt fail.
