- Why didnt Sasuke get his arm replaced?
- Will Sasuke eventually get his arm back?
- Why didn’t Sasuke get both rinnegan?
- Why did Sasuke only awaken 1 Rinnegan?
- Why Sasuke has 6 Tomoe Rinnegan?
Sasuke would never get his arm back for the remainder of Naruto Shippuden, as well as Boruto. Sasuke didn’t get a new arm because he wanted a constant reminder of his troubled past. His self journey of personal atonement would feel cheated by replacing the lost arm which represented the build up of all his sins.
Sasuke will not get his arm back, he does not want it back. Sasuke’s missing arm is penance for his past crimes, punishment for the many lives he has destroyed and taken while on his path of darkness, and a reminder of why he is now on a mission of atonement.
No two Rinnegans? Hagoromo prevented him from having two. Same reason that Sasuke has sharingan active in his Rinnegan eye. Hagoromo sped up Sasuke’s rinnegan awakening, made it active in only one eye and ensured he could use Sharingan with it.
The reason is, Sasuke has literally half of Hagoromo’s chakra. He already had Yin chakra from Indra’s soul. When he met Hagoromo, he got yin part again and naturally, awakened only one rinnegan.
Back to the question, recall that Sasuke received half of Hagoromo’s (aka Sage of Six Paths) chakra, thus awakened the Rinnegan. The Rinnegan Sasuke has is quite unique, it has 6 tomoe split between its first two ripples, this doesn’t mean nothing, it indicates the Rinnegan is fully charged.
