Awakening Dojutsu twice?

[Mitarashi]

So, as the title suggests, can you awaken Dojutsu ( Sharingan/Rinnegan ) Twice?

As Tobirama ( The font of Uchiha wisdom ) said, the Uchiha love the most ( They are the hippies of NV ) when a Uchiha that has known love looses it, It turns into an ever more powerful hatred 'Special chakra sprouts from their brain and effects their optic nerves and produces a change in their eyes'

So, if you were to implant a new eye, wouldn't it become a Sharingan?
The chakra is still linked to your optic nerve, is it not?

Even if it didn't, if you were to experience a trauma again, would the eye you had ( Any eye at all ) Become the sharingan? As it's really their brain that's doing it?

This may be obvious to some of you, but I'm an idiot, so enlighten me.

Yeah, i believe you can.

 

[johnny scars]

well done nice finding!

 

[questin1]

idk about that though, it would make sense.

 

[Kishi Uzumaki]

Yeah But there is a problem . if it's their Special chakra sprouts from their brain effects change in their eyes how did kakashi awaken mangkyo .

It was because Obito awakened his, Or the Hatake family has Uchiha blood.

Anyway, would this mean that the Mangekyo sharingan created from the 1 person would be the same every time?
Would Obito keep making Kamui sharingan?

 

[Kishi Uzumaki]

It could because obito awaken the mangekyo when kakashi awaken his or hatake have uhiha blood some how . obito must have awaken it in his left eye but it was just a sharingan . tobirama doesn't know this that's why I'm waiting for kakashi to come out from other dimension see how tobirama respond .

Ah took a second read to follow you.


Theoretically you'd be correct. The only issue would be if the chemicals in the brain have to specifically react to a particular genetic code found in Uchiha eyes.


If so then only taking some other Uchiha's eyes would work as other eyes would lack the genetic code the brain's mutated chakra interacts with.


It is good to note that opposite to the Hyuga, Uchiha have noticeably black and somewhat pupiless eyes...a unique eye trait for the most part.



But under the idea that its the chakra alone....you'd technically be right.

Maybe we will find out some day, eh?

In the meantime, all uchihas give your Eyes to Madara to awaken ultimate MS.
