1. Naruto's Mother - Kushina Uzumaki: Kushina Uzumaki, also known as the "Red Hot-Blooded Habanero," was the mother of Naruto Uzumaki and the former Jinchuriki of the Nine-Tails. Her resurrection would create an emotional conflict for Naruto and Sasuke. However, it's unlikely to happen due to potential backlash from fans.

2. Fugaku Uchiha: Fugaku Uchiha, Sasuke's father, could become a formidable adversary if resurrected.

As the head of the Uchiha clan, he possessed immense power. However, his resurrection has been avoided to prevent conflict between Sasuke and his father. It remains uncertain if Naruto and Sasuke could defeat him.

3. Shisui Uchiha: Shisui Uchiha was a genius of the Uchiha clan and possessed powerful genjutsu abilities. His resurrection would trigger a battle between Naruto, Sasuke, and the Shinobi Alliance due to his ability to control minds.

It's unlikely for Shisui to be brought back.

4. Jiraiya: Jiraiya's emotional significance as Naruto's mentor makes his resurrection unlikely. Additionally, obtaining his DNA for resurrection is impossible as his body sank into the ocean. A battle between Naruto and Jiraiya would be emotionally challenging and unwanted by fans.

5. Hagoromo Otsutsuki: As the Sage of the Six Paths, Hagoromo possesses unparalleled power. His resurrection would lead to the immediate resolution of conflicts in the Shinobi world. However, according to the storyline, Hagoromo cannot be resurrected, as it would potentially end the Naruto series.
