Summary
Jujutsu Kaisenhas an array of very powerful individuals who possess tremendous strength up their sleeve. Among the stronger sorcerers, there are those who can essentially kill anyone in one shot and completely destroy them in combat.
These Jujutsu users are very rare, however, they have abilities befitting their standing in the world. Thanks to their amazing powers, they are feared all over the world, and for all the right reasons. Over the years, fans have been introduced to quite a few attacks inJJKthat can kill in one shot, and, needless to say, these attacks are special.

6Maximum: Uzumaki
User: Suguru Geto, Kenjaku
Maximum: Uzumaki is the strongest technique of Geto Suguru’s Cursed Spirit Manipulation. This technique was used first by him during the Night Parade of a 100 Demons, and later by none other than Kenjaku towards the end of the Shibuya Incident.
Essentially, this attack sees him utilize every single cursed spirit that he has absorbed into one and launch a powerful beam created by their cursed energy at the target. This beam is absolutely devastating and can destroy almost anyone in one shot, making it one of the strongest techniques that fans have seen in JJK to date.

5Idle Transfiguration
User: Mahito, Kenjaku
Idle Transfiguration is one of the strongest cursed techniquesthat fans have seen in the story. This cursed technique belonged to none other than Mahito, and was later used remotely by Kenjaku as well. Idle Transfiguration allows Mahito to manipulate souls as well. Essentially, he can destroy souls, as well as reshape them according to his will.
He can completely destroy anyone with a single touch of his palm. This makes his abilities one of the most dangerous ones in the entire series. Inside his domain expansion, things get even more dangerous as he doesn’t even need contact to destroy his enemies. Undoubtedly, Idle Transfiguration is one of the most amazing techniques inJJKand one that can easily kill in a single shot.

4Black Hole
User: Yuki Tsukumo
Yuki Tsukumo possesses the power of Star Rageand this allows her to add imaginary mass to herself as well as her shikigami, Garuda. Yuki possesses quite a lot of amazing abilities and certainly, one of the strongest and the most dangerous one of them all is black hole.
This ability, as is evident from the name, allows her to create a black hole so powerful that she can destroy the world. Yuki cannot just kill in one shot, but ruin all life if she so wishes. Truly, this attack is fearsome and might rank among the very best in the entire story. The raw power it possesses can hardly be matched by any other technique that fans have seen in JJK.

3Malevolent Shrine (Cleave And Dismantle)
User: Ryomen Sukuna, Yuta Okkotsu
Sukuna’s cursed technique possesses quite a lot of dangerous attacksthat can kill in one shot. As fans know, his cursed technique launches a barrage of powerful slash-based attacks at the opponent, slicing and dicing them in the process.
Sukuna possesses three powerful cutting attacks, and these are Dismantle, which is the regular slash that he sends flying from a distance, Cleave, which is also a slash, however, one the size and strength of which depends upon the target, and of course, the newly required world slashing Dismantle, which can cut anything in the entire world by expanding the target of the attack. Any of these attacks can kill in one shot if they are launched from a close enough proximity, with enough cursed energy behind them.

2Hollow Purple
User: Gojo Satoru
Hollow Purple isone of Gojo’s strongest techniques, if not the strongest. This technique sees him collide the two infinities of red and blue together, to give rise to an imaginary mass that deletes anything in its path, completely erasing it from existence upon touching them. Hollow Purple is an incredibly powerful technique that can easily kill nearly anyone in one shot.
In fact, even Sukuna believed that taking a Hollow Purple at full strength from a very close range would lead to his death. Sukuna ended up taking two Hollow Purples, however, both of them were from a distance, and thus, he survived. The first was launched from a few miles away, while the second one was a remote Hollow Purple and, thus, not at full strength. This is clearly a technique that can kill even the strongest in a single attack.

1Unlimited Void
By far, one of the most dangerous attacks that can kill in a single shot isthe Domain Expansion of Gojo, Unlimited Void.As fans know, Unlimited Void is a powerful domain expansion that barrages the enemy’s mind with infinite amounts of information, paralyzing them and frying their brains completely.
Even being in this domain expansion for a few seconds can be deadly for anyone, and even the King of Curses cannot sustain the incredible might of Unlimited Void for more than a few seconds.
