"Eye to Eye: Sharingan vs. Sharingan!" (写輪眼VS写輪眼!!, Sharingan tai Sharingan!!) is episode 82 of the original Naruto anime.
Kakashi and Itachi exchange blows, each being very proficient with the Sharingan. Itachi, however, is more so, having access to the Mangekyō Sharingan, and quickly attacks Kakashi with his Tsukuyomi. With his genjutsu, Itachi tortures Kakashi for what he perceives as seventy-two hours in seconds. As Kakashi struggles to remain standing, he asks Itachi why he has returned to Konoha. Itachi replies that they're after Naruto. Kakashi remembers a conversation with Jiraiya, where Jiraiya tells him that he has been monitoring Orochimaru's activities ever since he left the village, and adds that at one point, Orochimaru joined a rogue organisation known as the Akatsuki, an organisation Itachi is a part of. Jiraiya also tells Kakashi that due to Naruto possessing the Nine-Tailed Demon Fox inside him, he will have to live the rest of his life watching his back, and therefore he will be taking over Naruto's training. Kakashi elaborates Itachi's words as meaning they want the Nine-Tailed Demon Fox for the Akatsuki. Angered that Kakashi knows of their organisation, Itachi instructs Kisame to kill Asuma and Kurenai, but to bring Kakashi with them. Before Kisame can do so, Might Guy arrives, forcing the two with no choice but to flee.
Meanwhile, Sasuke returns to the Uchiha Clan's basement and is angered as he remembers his clan's massacre. Jiraiya attempts to bring Naruto with him on his search for Tsunade; Naruto initially refuses, as he wishes to stay in Konoha so Kakashi can teach him the Chidori. Jiraiya tells Naruto that he's prepared to teach Naruto a jutsu that is stronger than Chidori, and this convinces Naruto to tag along with Jiraiya.
- Kakashi did not have his scar at the instant after Might Guy saved him.
- When Itachi uses his Mangekyō Sharingan on Kakashi, his eyes do not change; instead, they remain as his three-tomoe regular Sharingan. This is because at the time the original episode aired, Masashi Kishimoto had not yet designed the Mangekyō Sharingan.
