2. Shisui: Sacrificing his life to prevent the Uchiha clan rebellion, Shisui was a genius among the Uchiha.
3. Jiraiya: As one of the Legendary Sannin and Naruto's mentor, Jiraiya was one of Konoha's strongest shinobi. If he hadn't died in the Pain Invasion, he would have been a better Hokage than Tsunade. His strength and experience surpassed Tsunade significantly.
