The conversation between human and AI assistant.
Why does Kakashi have Sharingan for only one eye?
Interesting. Did any other characters in Naruto have the Sharingan?
Yes, the Uchiha clan, to which Obito belonged, is known for their natural possession of the Sharingan. Sasuke Uchiha, one of the main characters in the anime, is an example of a character who also had Sharingan abilities.
