The Uchiha's eyes are the swiss army knife of eyes, they have everything and can do everything.
Speaking of their eyes, can someone explain to me how does transferring ones Mangekyo eyes into another give you Eternal Mangekyo.
I mean my understanding of how it's suppose to work is that once you gain the Mangekyo you start losing your sight, the more you use its powers the quicker you lose your sight. And in order to regain your vision and more powers even, you have take the eyes of another Mangekyo sharingan user. That's what I remember.
Now maybe I'm the only one that thought about this, but how does transferring the eyes of someone who's losing their vision gets you back your vision? My understanding is that in order to get the Eternal, you need the eyes of someone who's got the Mangekyo, so someone who's losing or lost their sight. How does getting rid of your bad eyes and getting another's bad eyes gets you good vision?
I mean I know the whole transferring eyes thing was mainly so Itachi can scare Sasuke, at least in that point, but eventually it became the rule of how it works.
Story wise I'd guess that the intent of the transfer is to basically how do I put this. its combines the two eyes into one super eye effectively wiping out the weakness of the individual eyes. and opening access to the full power of the eyes
individually the sharingan while powerful cant handle the raw chakra needed to use all the special powers the human eye can only take so much power flowing through it without damaging it
so the double mangekyo reinforces the eye to superhuman levels which allows it to channel chakra more easily meaning there's no risk of blindness as the eye no longer deteriorates with each use
Cat gave the best excuse for how it possibly works; a single set is incomplete and damages the eyes causing blindness, combining two sets somehow stabilizes the eyes' power, and also restores the sight.
As for story-wise the problems with it was a mixture of kishimoto's habit of trying to keep powers and Ninjas balance, a reason for Itachi's actions, and his obsession of the Sasuke Naruto rivalry.
1) Kishimoto tends to prefer not to make broken characters or abilities. Characters tend to be specialist that are good at one form of fighting while poorer in other fields to justify teamwork...that never really happens. While powerful abilities tended to have draw backs.
From what I recall Dosu of the Sound was killed because Kishi thought he was too well balanced compared the rest of the genin during the chunin exam. Neji and Lee were close range fighter that lack range attacks. Gaara was a defensive stationary fighter, Shikamaru's shadow powers lack offensive abilities at the time, Kankuro relied on surprised and his puppets, Temari her fan, and Shino his bugs. Look at any fight Dosu was in, he was very versatile with his vibration gauntlet that made any fight lean in his favor unless there was a massive power discrepancy.
Team 7 should had in part one in theory had: Naruto was their close combat focus fighter that could scout, Sasuke a close-mid range ninjutsu fighter, Sakura a long range genjutsu support, and Kakashi an all-rounder with a problem with his stamina.
The Rasenshuriken couldn't be thrown at first for example of powerful abilities having limits and damages the users showing drawbacks. So, the same with the Mangekyo a fire that can't be put on, instant unbreakable illusions, and summons a giant invincible armor spirit all for the price of slowly losing your eye sight.
2) Originally, at least before he finally drew him, Itachi was suppose to be evil. An evil power hungry monster that murder his entire family to gain the power of the mangekyo sharingan and his reason for not Killing Sasuke was; he needed him to be his second set to gain even more power. Of course that was abandon for what both consumed both Kishimoto and the story all things to fuel that drawn out Naruto-Sasuke conflict.
3) As all should know Kishimoto was obsessed with the final battle being a final fight between Sasuke and Naruto and spent large portions in trying to justify it. One of his obsession was Sasuke and Naruto must be equal in power no matter how strong Naruto got. The thing due to being the container of Kurama once he gained access to his power Naruto would become instantly one of the strongest ninjas to ever exist. How was Sasuke suppose to match this? At first Kishimoto gave him the curse seal, but he clearly thought it would be stupid if it got passed the level 2 staged. So that left him with things like the Sage mode which Sasuke doesn't seem the type, or power up the sharingan till it could match the power of the nine-tailed fox. He went with the latter. So, the more powerful Naruto got the more broken the Mangekyo sharingan had to be to match him.
