1. Yahiko: Yahiko, a carefree person with long bangs and a blue robe, resembles Boruto's Sasuke. As the host of the Six-Tails, he lost faith in his master when they tried to extract the Tailed Beast. However, he found hope in Ying, a girl who wanted to be his disciple. Unfortunately, he was captured by Pain but managed to pass his hopes for life to Ying before his last breath.

2. Izuna Uchiha: Izuna, the brother of Uchiha Izuna, activated the powerful Mangekyou Sharingan. He looks similar to Sasuke in Naruto's later part.

After being heavily injured by the Second Hokage, Tobirama, Izuna lost trust in others and pursued peace in his way by activating the Eternal Mangekyou Sharingan.

3. Sai: Sasuke's departure disbanded Team 7, but it was reinstated with the addition of Sai. Despite a physical resemblance to Sasuke, Sai lacks his unruly nature. Trained under Danzo, Sai is more disciplined and military-like.
