Uchiha in Sword Art Online

A guy reincarnates in SAO in Kirito's place, and he has the Uchiha bloodline from Naruto with the bonus of an Eternal Mangekyo Sharingan that is allways on! A/N: I've been thinking about a fic with an mc that has the sharingan for a wile now, BUT THE THING IS TOO OP TO FIT ANYWHERE!!! a sharingan with no mangekyo is no fun, a mangekyo that drives you blind as well. so i wanted to have it at the eternal stage from the start, but the the real problem is the initial stages of the sharingan! most anime universes can cope with susanoo, and i can try to make the 2 personalized abilities balanced, but the ability to copy every spell and martial art to perfection with just a glance is streaching, and the ability to put anyone under illusions so strong that they have been used to enslave gods is just plain reality breaking! like, meet the last boss and turn it into a slave before he can do anything! oh, and if you have the sharingan, this also means you are a ninja from naruto world and can use chakra and cast jutsus -_-... so i decided for SAO. i don't usualy like nerfs, but this was just needed! mc will not be able to use most of the sharingan's powers in the digital worlds, he will prety much just have te enhanced perception and eyesight the sharingan gives for most of the fic, in the material world he will have acess to all of his bloodline's powers but he will not have a good mastery over it as he never practices
