Ok before I start, I would like to state I am in no away trying to justify everything that happened in Chapter 688. I’m still upset about O-Casper moment in this chapter. What I would like share are my conclusions about the Uchiha’s Kekkei Genkai (UKG) Sharingan and how Kakashi achieved Mangekyō Sharingan (MS) through his non-Uchiha eyes.

First, how the Sharingan is developed: In a moment of clarity I realized that the Uchiha’s Kekkei Genkai (KG) ability is not the Sharingan. The Sharingan is one of the many results of the clan’s KG. The Uchiha’s KG is actually the ability to mutate the biological make-up of the eye. Using unique neuron-signals initially triggered by mental trauma. Like a ware-wolf changing ability or Bruce banner turning into the Hulk.

For example, remove the eyes of an Uchiha child that has not yet developed the Sharingan into an individual that that does not possess the Kekkei Genkai. The user’s (non-Uchiha) eyes will never develop the Sharingan during the indivuals life spawn even though the eyes originally belonged to an Uchiha. The mutation can only be performed by an individual that possess the Uchiha Kekkei Genkai (UKG). This mutation also includes changing the eye back to its original biological make-up. This is why Kakashi and Danzo (non-UKG) could never turn the Sharingan off. The eyes were stuck in the form the non-UKG user received them.

“So if that’s true, how does Kakashi have the ability to mutate his eye from Sharingan to Mangekyō Sharingan (MS)?” The answer is his own unique ability to recreate what he sees, feels, or experience. I imagine that Kakashi was able to copy two UKG neuron-signals when Rin died. This is possible because Obito and Kakashi were mentally connected at the time, as clearly shown that Obtio was receiving visual signals from his disembodied eye. Kakashi’s brain, although unconscious, was able to mimic the experience of the UKG neuron-signals used to mutate a Sharingan to Mangekyō Sharingan and back once Obito calmed himself.

With all that said. I hypothesize that a highly skilled UKG user could mutate a set of eyes remotely (meaning the eyes are not implanted in the user). This has been implied twice at Rin’s death and the Death of Itachi. Itachi was able to store the UKG neuron-signal to trigger when seeing Obito’s face (Dude was ahead of his time).

Now let’s take the next step, if the UKG is the ability to re-map the eye’s biological tissue through neuron-signals this would conclude that a UKG user could achieve the Sharingan through non-Uchiha’s eyes .

“Why didn’t Kakashi mutate a new Sharingan on his own or mutate both eyes long ago?” Remember he never had the opportunity copy UGK neuron-signals for normal eye to Sharingan and vise-versa. So basically Obito’s Ghost (it makes me sick to say that) re-linked to Kakashi and showed him the incomplete UGK neuron-signals; normal eye to Sharingan.

NOTE: Side note although I’m not ready to explain it fully. Technically since its Obito’s UKG neurons mutating Kakashi’s eyes would make Kakashi’s current MS, Eternal Mangekyō Sharingan. Giving him the possibility to use Perfect Susanoo.

That actually makes sense !! But here is my question !! We saw that in sasuke and madara that their MS pattern changed when they achieved EMS . as far as i see kakashi's pattern is the same as before ( MS ).

I think we should wait for an explanation in next chapter.

kakashi is able to use the mangekyou because its original user was still alive, it was actually obito that activated both mangekyous because he was still linked to it thats why he was seeing thru kakashi's eye back when Rin died..you'll also notice that both eyes where in sync during the activation..a non-uchiha cannot activate the mangekyou but if the mangekyou is already activated, then a non-uchiha can switch between mangekyou and sharingan like in danzos case...obito's was a special case since he didn't die....

I think it KkG is the special chakra released from the brain. It's the chakra that mutates the eye. When Obito connected his special chakra from death to Kakashi he was able to mutate Kakashi's normal eyes to his eyes. That's why it looks the same after death. Hints have been giving when Tobirama explained the Curse of hatred. Also it's the reason why EMS maintains both users patterns despite only being one users eyes. The transplanted eye retained chakra from the original donor (Sasuke stating he can feel Itachi chakra) and combines with the new users special Chakra thus giving the combined look.

I think it might because of the residual effect of an existing MS pattern. The combination of two, Kakashi's doesn't have a pattern of his own.

I mostly agree, I just think the only reason Kakashi could switch back and forth between mangekyou and sharingan is because his ability to memorize the mutation at that time. I'm not sure if i ever remember Danzo actually mutating an eye. I'll have to go back and study his battle with Sasuke.

This is very possible too. I see chakra as a combination of energy signatures and brain-wavish thing that can hold memories.

Actually the more i think about it KaKashi and Obito have always shared the same MS pattern. So even tho Kakshi is using EMS the pattern would look the same as MS.

well in kakashi's case, the mangekyou was activated by obito but kakashi didn't know that so he grew up utilizing the sharingan unaware the mangekyou was already activated until he took the time to focus his chakra.that's when he was able to use it agaisnt Deidara ..he said himself he noticed t when he was training back in the "rescue Gaara arc"

I think we are mostly on the same page but i do believe that without Kakshi abilty to mimic he would have never been able to active it again without obtio. I think while he passed out his own ability was still active and record Obito's activation. But as you said could not recall until later in life like a suppressed memory.

This kind of goes back to my own theory that once Kakashi copied a jutsu the inherent brainwave activity is retained in Kakashi's memory. So even though he no longer had Obito's eye the brainwave shift that causes the mutation was still there. Since he is not an Uchiha he couldn't access it on his own.

When Obito's spiritual chakra(for lack of a better term) entered Kakashi's body, that mutation was triggered mutating his own set of eyes if that makes any sense. So I can see what you are getting at here which does lend some credibility to your theory.

Just wish it had actually went down a bit differently in the manga, like Obito's last act before dying was to imprint this chakra of his into Kakashi and not after the fact.

I agree 100%. I hate the whole ghost idea.

Okay but how is Kakashi going to handle the additional stress on his chakra? I suppose now he can deactivate the sharingan to conserve? Or is this asspull EMS just more chakra conserving naturally. All throughout the story Kakashi kept the eye covered because it drains alot of his chakra due to not having uchiha blood....

Although I think the EMS will go away once Obito's chakra runs out. EMS is extremely chakra efficient. Notice that all ems users never shut down their Sharingan.

I suspect that Obito's ghost will shut Kikashi eyes down to normal before he vanishes. Kikashi will retain up to MS.

Best way to defeat Obito: Call Ghostbusters cause logic is not in the manga anymore so they could probably fit in aswell

I think that it wasn't Kakashi that activated MS in the first place because Obito was there aswell. You get MS by experiencing something very disappointing and tragic in your life in front of you just like Obito saw Kakashi kill Rin infront of him. So Obito activated it for both of them.
