There is a reason Jujutsu Kaisen has become a worldwide phenomenon. The series is already considered by many to be a modern classic. JJK fans usually tend to cite the incredible story, complex power system and beloved characters as the main reasons behind its success, but the action of the series is truly second to none.
Right from the start, Jujutsu Kaisen turns the action up to 11 in some of the most incredible fights in anime history. These fights are so incredible to watch that even detractors of history can't deny their insane scope and impact. JJK Season 4 is about to feature the best battles of the series.

Takaba vs. Kenjaku is unlike any other fight in the series
The only way to defeat the ancient villain
Kenjaku was the mastermind behind the Culling Game and basically the entire story of Jujutsu Kaisen. As an ancient wizard who was one of the most powerful of all time, Kenjaku promised to be the greatest threat in the world after Sukuna himself, and many were worried about how to even defeat this villain.
The Shinjuku Showdown arc revealed the most unlikely answer to this question: Fumihiko Takaba. Recruited into the ranks of the heroes, this mad wizard took on Kenjaku in one of the strangest and most unique battles ever seen, teleporting around one second but having a water fight another due to The Comedian's reality-altering powers. While the ending of this fight is divisive to some, Takaba vs. Kenjaku still one of the highlights of the Shinjuku Showdown arc.

Yuki And Choso Vs. Kenjaku shows the power of special grades
An amazing strength
Since this battle was first teased at the end of the Shibuya Incident, Yuki and Kenjaku were destined to clash for quite some time. They would eventually cross paths in the middle of the Culling Game arc in a battle that showed the true extent of why some wizards are designated special ratings, as these two are some of the strongest characters in the series.
In one of the bloodiest and most destructive fights in Jujutsu KaisenYuki showed why she belonged on the same level as Gojo and Kenjaku showed why he has been one of the biggest threats in centuries. Even though Choso wasn't quite on their level, his inclusion in this battle on Yuki's side proved crucial to his character arc, as it put his entire journey into context.

Hakari vs. Kashimo is the most fun fight in JJK
The player vs. The lightning god
Although Takaba vs. Kenjaku is the most frivolous and fun fight in the story, Hakari's fight against the deadly Kashimo is by far the most exciting and one of the high points of the franchise as a whole. Going into this battle, everyone knew that Kashimo was a terrifying opponent who was the strongest in the Edo period and had lightning powers, which did not bode well for Hakari.
However, the player proved everyone wrong by displaying the full power of his Private Pure Love Train technique, which was one of the most hyped moments of the entire arc. Repeatedly opening his domain and the two of these fighters duking it out while the theme song of Hakari's favorite show plays in the background, this fight is sure to leave all fans completely engrossed with a big smile on their face.

The Sukuna raid was the only way to defeat the monster
All against Sukuna
After his battle with Kashimo, Sukuna stood tall as the greatest wizard in the world, proving himself capable of stopping anyone who would stand up to him. Since this was something everyone else also knew, the ultimate plan to destroy this villain came to fruition, pitting all of Jujutsu High and their allies against the King of Curses.
The closing of the Shinjuku Showdown arc was basically a gauntlet that Sukuna had to complete, fighting powerful wizards one by one, each with their own strengths and roles to take down the villain. More than just creating incredible action, this final recap also featured many deeply personal and emotional moments.

Jujutsu Kaisen: 7 Characters Who Could Have Defeated Sukuna (Under The Right Conditions)
Despite his seemingly unstoppable nature, there are a few JJK characters who could have killed the King of Curses at various points in the story.
1
Gojo vs. Sukuna has the creation of the greatest anime battle of all time
History's strongest vs. today's strongest
There are very few fights that have ever, or ever will, match the ultimate battle between Gojo and Sukuna, which was created since the first episode of the series. The strongest wizard in modern times finally went up against the strongest wizard in history in a battle that was the ultimate test for both of them.
During the publication of the original Jujutsu Kaisen manga, fans tuned in for 14 straight weeks to see how this battle would play out, taking to social media to discuss every minute. The state the anime/manga world experienced during the serialization of this fight is something that may never be seen again until this battle is finally animated, proving that Gojo Vs. Sukuna is destined to go down as one of the highlights of the industry as a whole.
