Jujutsu Kaisen is known to be heavily inspired by Naruto in its character designs and arcs. However, not many JJK fans realize that Gege Akutami could’ve even copied ‘techniques’ from one of the top three Shonen franchises.
‘Copy’, regarded as one of Jujutsu Kaisen’s strongest abilities, is strangely similar to the Sharingan of the Narutoverse. Both have the ability to mimic a multitude of techniques from opponents. Moreover, there is no limit to it, meaning that they can unconventionally copy any ability.
The Similairities Between ‘Copy’ in Jujutsu Kaisen & Sharingan in Naruto
Copy is Yuta Okkotsu’s special Cursed Technique in Jujutsu Kaisen. The ability was first revealed in Chapter 178 during a three-way death battle between Yuta, Ryu, and Takako. After storing Cursed Energy and abilities throughout the series, Yuta summons Rika with his ring and uses the Domain Expansion technique that he couldn’t use before.

Speaking of Sharingan, the ability is passed down to generations in the Uchiha family. It has three stages: the first allows users to copy ninjutsu and taijutsu, the second allows the copying and dispelling of genjutsu, and the third branches out to several different modes. Sharingan is first introduced in Naruto Chapter 12.
While Sharingan can mimic any jutsu and render the user immune to the opponent’s attacks, Copy can steal any technique as per the limitations of Rika, the vengeful spirit connected to Yuta. Both techniques can be overpowered by using clones followed by outwitting the user with the execution of a completely different ability while they are distracted.

Differences between Copy and Sharingan
While the concept of Copy in Gege Akutami’s Jujutsu Kaisen is taken from Naruto, there are subtle differences between them as well. Copy can only be used when Yuta is connected to Rika and its power is limited to the latter’s form, which is believed to be infinite as of now. Sharingan needs no connection and instead requires copious amounts of chakra.
Copy can also help a user mimic and learn a different language. As seen in Jujutsu Kaisen Chapter 0-4, Yuta learms Cursed Speech by replicaticating Toge’s ability. He is able to negate Geto’s swarm of lower-grade curses and becomes more proficient with it as the series progresses.
Sharingan cannot help mimic speech due to being strictly limited to techniques. However, it does get an edge over Copy because it can enhance the user’s perceptive abilities and other attributes alongside mimicking any jutsu. Yuta’s technique does not enhance the copied move or his ability.
This aspect can be seen in Chapter 179 of Jujutsu Kaisen. In the previous chapter, Yuta, Ryu, and Takako simultaneously used Domain Expansion and cancelled each other’s technique. The story would’ve been different if a Sharingan was used by any of the JJK character since Domain Expansion is also a jutsu.
