The only idea he had was to attribute to Itachi some violent action that would have Sasuke wanting to kill him. When Itachi Uchiha is first mentioned by Sasuke Uchiha in the manga, Masashi Kishimoto had not planned out the character's backstory. Numerous types of merchandise have been released in Itachi's likeness, including keychains, plush dolls and figurines.
The gradual revelations of his past and its impact on the story has also received positive reception, and his fights were noted to be "one of the best" in the series. His appearance as an antagonist has been praised by several writers, although some have considered his initial appearance to be unsurprising. Itachi's character has been popular with readers of the manga, and has been positively received by critics. Itachi is a playable character in most of the video games from the series. Although Itachi perishes during the final duel, it is later revealed that Itachi had a secret reason for assassinating the Uchiha clan. During the second part of the manga, Itachi becomes involved in attacks to ninjas possessing tailed-beast creatures until facing Sasuke in a one-on-one battle. He appears working as a terrorist from the organisation Akatsuki and serves as Sasuke's greatest enemy. Itachi is the older brother of Sasuke Uchiha, and is responsible for killing all the members of their clan, sparing only Sasuke.
Itachi Uchiha ( Japanese: うちは イタチ, Hepburn: Uchiha Itachi) is a fictional character in the Naruto manga and anime series created by Masashi Kishimoto. Robbie Daymond (Rock Lee & His Ninja Pals) The blood relation mightve been a theory in the manga, an assumption, misused information.Skip Stellrecht ( Naruto Episodes 29–30) When the body is introduced to a pair of eyes from somebody else it would react differently, my guess is if the reciever had MS, they could potentially awaken EMS when the donor MS is transplanted into them regardless of blood relation. Why this is important is because his "children" also have the same pattern implying those who have the exact same dna would awaken the same MS with the same power. Shin's body is tattered with sharingans implying no matter where you put em, the sharingan will work. This also assumes the donor is still alive (Madara did say killing sasuke would be a waste of those eyes implying sasuke would resist) The instinct of putting the donor eye into his eye socket probably means that the eyes dont fuse (Madara already as EMS which is why Obito's stay they same in Madara's eye socket). And what he did to Kakashi just before being sliced in half by Sasuke was taking his (Obito's right eye) and planted it into his socket.
Madara said to Sasuke "maybe I should take your eyes before i get my rinnegan back" just after his full revival. What Madara said and did during the 4th war Two additional points to consider as per why theyre not fused: If point 4 is also necessary then they can't simply exchange eyes as one needs to die before the other can transplant their eyes and awaken EMS. If point 3 is also need to be met then they still can exchange eyes after exhausting their eyes, making it near blind. If, only the first two conditions are necessary for the EMS then yes, any close relative that has awakened MS can simply exchange eyes for both to awaken EMS. IIRC it was told in the manga that transplantation is better done between close relative since they are more compatible.
Is shown to have awakened Mangekyou Sharingan (henceforth the MS).
