After the final battle at the valley of End, both Naruto Uzumaki and Sasuke Uchiha ended up losing an arm. I’m going to discuss what would’ve happened if Sasuke also received an arm made of Hashirama’s Cells.
The clash also destroyed most of the Final Valley.
After their reconciliation, Naruto ended up getting a prosthetic arm made from Hashirama’s cells, while Sasuke opted not to get an arm.
The arm also boosted Naruto’s already amazing regeneration powers, and his chakra prowess.
