1. Nara Shikamaru: Intelligence is crucial in the ninja world. Shikamaru's intelligence compensates for his lack of power. If he turns dark, capturing him would be difficult.
2. Uzumaki Naruto: Naruto's strength is unmatched. Only Uchiha Sasuke can rival him. If Naruto falls into darkness, the consequences would be worse than Uchiha Madara's.
3. Hatake Kakashi: Kakashi is one of the most powerful individuals.
4. Jiraiya: Few can match Jiraiya if he falls into darkness. With his Sage Mode and vast knowledge, the Akatsuki would struggle to confront him.
5. Tsuchikage Ohnoki: Ohnoki's deep understanding of the ninja world and cunning make him formidable. If he falls into darkness, it would create trouble similar to the Akatsuki.
