After the Fourth Great Ninja War and his final conflict with Sasuke, Naruto lost his right arm, and Sasuke lost his left. Unlike Sasuke who remained amputated, Naruto has a new arm, but why is it wrapped in bandages?
1. The wrapped arm is Naruto’s prosthetic arm
The wrapped arm on Naruto’s right side is his prosthetic arm, which he uses as a replacement for his destroyed limb. Tsunade created this prosthetic arm, but why is it wrapped? It is likely due to its appearance being significantly different from Naruto’s normal left arm. Maybe the difference is quite noticeable, unlike the new prosthetic arm made by Katasuke, which Kawaki uses now.
2. The appearance of Tsunade’s prosthetic arm remains unknown
However, the appearance of Tsunade’s prosthetic arm behind the bandages remains unknown. But since Tsunade made it from Hashirama cells, my theory is that it may look like the White Zetsu’s arm, which is pale white. The difference from Zetsu’s hand on Madara and the Hashirama cells on Obito is that Naruto’s prosthetic arm may have some other mechanical elements and looks like it has a detachable connection (not permanent, unlike Madara or Obito’s cases). Meanwhile, Katasuke’s more sophisticated prosthetic arm probably doesn’t need wrapping because it looks like a real hand. You can see it clearly on Kawaki’s arm.
3. Bandaging may be Naruto’s style
It seems that even if he replaces it with a highly sophisticated prosthetic arm, Naruto feels more comfortable using bandages on his fake arm. He used to wrap it even when he wore Katasuke’s prosthetic arm during sparring with Boruto. Perhaps this was to deceive Boruto, who at the time, didn’t know that Naruto’s right arm was a ninja weapon. So, wrapping the arm is entirely Naruto’s choice since Katasuke’s detachable prosthetic arm looks like a real hand. But it would be strange if Naruto suddenly had a perfect-looking arm without bandages after years of wearing them.
In conclusion, Naruto’s wrapped prosthetic arm made by Tsunade is different from Katasuke’s sophisticated prosthetic arm. The wrapped appearance of the arm is likely Naruto’s personal style, and he may have wrapped it to keep Boruto from noticing it was a ninja weapon during their sparring sessions. However, the mystery behind the appearance of Tsunade’s prosthetic arm remains unknown. It’s likely that the arm resembles the White Zetsu’s arm in terms of color. Still, there are probably other mechanical elements, and it looks detachable, unlike Madara or Obito’s prosthetic limbs.
