This is a fail thread. Kakashi is NO match for itachi.
why?
Kakashi is about 10 years older than itach (proven), but yet itachi out matched him a few times already (and it wasnt even 1v1 fight yet itachi was never injured) ex. itachi vs kurenai, asuma and kakashi vs itachi and then anruto and kakashi vs itachi. kisame admitted itachi was strong, and itachi admitted he wasnt even using half his str fighting kakashi and asuma and kurenai. even Tobi admitted that "itachi never seizes to amaze him"
itachi is an uchiha prodigy, he was in ROOT ANBU while still in his young teens. kakashi had just become jounin in his young teens.
itachi is was diseased, so it affected his stamina greatly, if not for this restraint he would be REAL O.P
itachi developed and mastered his sharingan (to MS) by the age of 8
Itachi has 2 rasengans, with MS, advanced susano'o, amaterasu, izanagi, izanami, he has shisui's eye, tsukuyomi, his genjutsu was so beast he would point at you or just stare at u nd u already fall into it. he has way more skills than this.
itachi easily scared off orochimaru. when no one in konoha was able to do shit to him.
the only thing in kakashi's side is Kamui which is hard to catch an opponent with bcs it takes concentration and time. (seen when he uses it on deidara when they were rescuing gaara)
also kakashi is a copy ninja
but no chance versus a prodigy such as itachi, kakashi was surpassed by his students, including sasuke, yet itachi defeated sasuke at his full strength (he only died from his disease and he never actually meant to kill sasuke only make it seem so) and kakashi couldnt even stop sasuke while he was already weak from fighting samurais, the kages, danzo....
