Explore the intriguing notion of Kakashi as a villain in Naruto, a concept that sparks curiosity.
In the anime Naruto Shippuden, standout characters are abundant, and one of them is undoubtedly Hatake Kakashi. Serving as the mentor to Team 7—Naruto, Sasuke, and Sakura—and holding the prestigious title of the Sixth Hokage in the Leaf Village, Kakashi is a jounin renowned as the 'Copy Ninja.' Gifted with the Sharingan left eye by Obito, he can replicate any technique of his adversaries.
Since his first appearance, Kakashi has consistently displayed clear loyalty to Konoha, always striving to protect the village with utmost effort.

However, let's consider an alternate perspective: What if Hatake Kakashi were an antagonist? How would he be?
To answer this question, Reddit user Raikriii decided to simulate this character from a villainous standpoint. In the user's imagination, as a antagonist, Kakashi not only possesses a menacing appearance but also wields two Rinnegan.

Maintaining two Rinnegan eyes would undoubtedly pose Kakashi with numerous challenges and obstacles, given his limited chakra reserves. It's certain that he would quickly deplete his chakra to sustain the Rinnegan or utilize the techniques associated with this ocular jutsu.
However, Kakashi is the kind of character who would likely learn to efficiently use his Rinnegan within his capabilities, similar to how he mastered the Mangekyo Sharingan, despite facing numerous limitations.
Additionally, another highly skilled artist has envisioned Hatake Kakashi as a villain, imagining him as a member of the infamous Akatsuki.

The artwork portrays Kakashi with a more serious demeanor, longer hair, clad in an Akatsuki cloak, and wearing a headband from the Leaf Village with a slash across it.
