Shin Uchiha is an interesting character that many fans have gained an interest in, he creates an antagony within the small Uchiha clan and is a good mirror to Sasuke’s character, often showing how far Sasuke has come from his days of anger and pain in Naruto: Shippuden.
Shin Uchiha, although not really an Uchiha, more on that later, is one of Orochimaru’s many orphans who lacks identity and instead latches onto one of Orochimaru’s obsessions in order to receive some attention from the notorious sannin.
Shin is a rather unique character that can get under fans’ skin, so let’s explore the lore behind him and why he may be the way he is. Let’s explore this character together!
Who Is Shin Uchiha?
Shin is basically one of Orchimaru’s test subjects and an orphan from Root. We do know that Shin was once of the Otogakure village, or the Village Hidden In Sound, and became a medical-nin at some point whether through his defected village, or through Orochimaru.
Either way, Shin was raised by Orochimaru and like many of Orochimaru’s orphans the latter imbues his obscured worldview into his orphans.
Orochimaru seems to have taken a specific interest in Shin due to the fact that his genetic makeup is unique and allows him to accept different cells and transplants without rejection, making him specifically useful to Orochimaru for understanding more about the Sharingan and of Hashirama’s cells.
As a result of this ideal genetic profile Shin has been implanted with multiple Sharingan, as well as many of Hashirama’s cells.
These body modifications have made him into a strong combative shinobi that is also trained in medical-nin, making him fairly noteworthy as an enemy. Taking on Hashirama’s cells like he has means that there are many clones made from Shin whom he refers to as his ‘sons’.
The right arm that Danzo Shimura had transplanted onto him is actually Shin’s right arm. While Shin could regenerate his arm, Danzo utilised the fact that Shin’s genetics don’t reject transplants as much as Danzo’s do.
It seems that Danzo wouldn’t have been able to handle having 10 Sharingan in his arm without rejecting them, until he transplanted Shin’s.
Seemingly through his training in medical jutsu, in addition to Orochimaru clearly influencing his world view, Shin is not only obsessed with the Uchiha, but with the idea of evolution.
He thinks that peace would cause an end to evolution; Shin believes that conflict is a necessary evil in order for evolution and natural selection to continue.
This is a sort of obscured version of the world view that Itachi had, that pain is necessary in order to learn, but Itachi’s philosophy was more about moral relativism and experiencing pain in order to achieve peace, while Shin seems obsessed with conflict and pain as scientific catalysts for the human race.
Is Shin Really An Uchiha?
No, clearly not. As mentioned, Shin is from the Otogakure village, Shin does not have Uchiha blood.
This is clear in the fact that all his Sharingan are transplanted rather than awakened, although Shin does have his own unique Mangekyou Sharingan, but this is why he has multiple Sharingan all over his body rather than the natural awakening of the Sharingan in the eyes.
Shin is obsessed with Itachi Uchiha as well as the clan at large. It’s not clear why he is obsessed with tachi, perhaps a misunderstanding of his ninja way, as mentioned previously, or perhaps this was something that Orochiaru conditioned into him with his own world view and obsessions.
As a result, Shin has a particular hatred towards Sasuke Uchiha. The first time we see Shin in Boruto, he has sent one of his clones to assassinate Sasuke Uchiha, in order to avenge Itachi and the Uchiha clan. It seems that Shin wishes to bring the clan back himself.
Shin adopts their last name, non consensually, as well as their clan garments, although Shin is not an Uchiha, he simply does this because he wants to. Some fans think that Shin hates Sasuke because he in fact killed Orochimaru, but most of the latter’s orphans hated him most of the time anyway.
Shin is particularly ruthless thanks to the importance he places on natural selection and evolution, he will try to push people past their limits to see how far they can go without breaking. For example he purposefully targets Sarada and Sakura as a way of drawing Sasuke out.
Moreover, he regularly kills his clones to protect himself, transplanting their organs into his own when he has been injured – making him a particularly troublesome foe.
His transplants have given him enough power to contend with Sasuke and Naruto, nearly killing less powerful shinobi such as Sakura without the intervention of Sasuke.
Is Shin Related To Shisui Uchiha?
This is a fan theory that has been floating around the Naruto forums and subreddits along with others that Shin is perhaps Shisui Uchiha’s son. That Shisui somehow survived jumping off a cliff with both eyes gouged out, and then had a child that has been orphaned.
We don’t think it requires much to point this out as a little ludicrous. The only thing could potentially add up is that the timeline could be relatively on point. If Shisui had a child it would be around the assumed age of Shin.
But that’s about it, and when you realise Shisui was around 15/16 (again, unspecified) when he died. While Shisui was powerful for his age, it would be pretty early for Shisui to consider making babies.
If we were to indulge this theory, Orochimaru would certainly jump at the chance to get his hands on an Uchiha, so if Shin was an abandoned Uchiha orphan, then Orochimaru would definitely be the one to take him under his wing.
But, this just seems unlikely considering the evidence we have. Shin certainly has an interesting genetic makeup that allows him to absorb all the transplants, so there is some interest among fans where this came from.
So, Shin Uchiha is an orphan who was taken under the wing of Orochimaru. He is capable of receiving many transplants of cells and organs without rejecting them, making him particularly useful to Orchimaru and Danzo’s plans. The latter received Shin’s arm which was implanted with 10 Sharingan.
While Shin is not of the Uchiha clan, he has adopted their name and attire, perhaps as a means to get back at Sasuke Uchiha, but he is not an Uchiha by blood, or in any way really. Many fans think he is related to Shisui Uchiha, but this is a speculative theory at best and doesn’t hold much weight.
