In the world of Jujutsu Kaisen, cursed energy reigns supreme. The more cursed energy a sorcerer possesses, the more powerful their abilities become (like Gojo’s Domain Expansion). On the other hand, the more cursed energy keeps on accumulating, the more monsters it gives birth to, like cursed spirits.
While jujutsu sorcerers are equipped with their abilities and weapons (powered by the same cursed energy) to fight cursed spirits, how many powerful characters from outside the Jujutsu Kaisen Universe (characters from other anime) can not only survive, but thrive in such a harsh world?
10 Would Survive: Saiki Kusuo Has Unlimited Powers (The Disastrous Life of Saiki K)
It may come as a surprise to many fans, but this teenage boy can easily keep himself safe from the antics of cursed spirits, irrespective of what their Grade is.
He possesses impossible powers like Curse (ensuring everything the spirits do, goes down the toilet), mind control, memory alteration and hypnosis (forcing them to stop fighting him and other humans), and teleportation (sends the spirits to a faraway place). Even if one of his powers won’t work on cursed spirits, he has dozens of others he can easily try on them.
9 Wouldn’t Survive: Shiemi is Mentally & Physically Weak (Blue Exorcist)
Even as an exorcist, Shiemi is one of the weakest ones from her class, both physically, mentally, and ability-wise. Her familiar Nee (which grows plants and creates barriers made from plants), would be completely useless in the presence of even the most basic of cursed spirits.
In fact, Shiemi is the type of character who’d easily be killed in the first few episodes of the anime, because she’s just that timid.
8 Would Survive: Rimuru Tempest is An OP Character (That Time I Got Reincarnated As A Slime)
The most unique aspect of Rimuru’s is that he’s able to gain the ability of whoever (or whatever) he chooses to consume. In his case, he’s already too strong for cursed spirits or cursed energy to have an effect on him.
If it ever came down to a one-on-one with cursed spirits, all he’d have to do is open his mouth, swallow his opponent and not only kill it, but also gain its powers.
7 Wouldn’t Survive: Ikoma's Kabaneri Powers Are Useless In Jujutsu Kaisen's World (Kabaneri Of The Iron Fortress)
With his regenerative abilities, enhanced speed, strength and powers, as well as heat resistance, Ikoma was quite the anomaly in his world full of regular human beings. However, in the Jujutsu Kaisen universe, while these powers are quite remarkable by themselves, they’re completely useless against cursed spirits.
In fact, Ikoma is the naïve and trusting type of character, which would make him an easy target for Special Grade cursed spirits like Mahito, who loves manipulating people.
6 Would Survive: Korosensei, because The Anti-Korosensei Weapons Don’t Exist In Jujutsu Kaisen's World (Assassination Classroom)
In his own universe, Korosensei is a nearly invincible octopus-like creature who possesses powers (like traveling at Mach 20) that most anime characters would kill to possess.
Without his weaknesses from his own universe, Korosensei would without a doubt be a creature that would be undefeatable in this new world, seeing how none of the cursed spirits or their tactics would have any effect on him – both physically and mentally.
5 Wouldn’t Survive: Senku's Only Power Is His Excessive IQ (Dr. Stone)
In the anime itself, Senku is shown to collapse (within a matter of seconds) while carrying water in a bamboo drum, something that Kohaku is easily able to carry herself over a very long distance.
Plus, Senku is a boy of science who has little to no tolerance for superstition and magic. In a world where sorcery and spirits exist, Senku, with all his knowledge of the world of science, would be at a complete loss, and seeing how poor his survival skills are, he wouldn’t be able to last for long in the Jujutsu Kaisen world.
4 Would Survive: Every Part of Gilgamesh's Body Exudes Magic & Power (The Fate Series)
This Archer Class Servant has nothing to fear because even without his massive arsenal of divine weapons inside his Gate of Babylon, he’s a force to be reckoned with.
His one soul possesses more than enough combined power of over hundreds of thousands of souls, which means that if he were to so chose, he'd simply use his raining Noble Phantasm technique to slaughter whoever stands in his way – cursed spirit, jujutsu sorcerer, or even completely innocent human beings.
3 Wouldn’t Survive: Mumen Rider From One-Punch Man Because His Superpowers Are Completely Useless Even In His Own Universe
Despite all his strength, speed, endurance, and good intentions, this C-Class Rank 1 superhero was pretty much useless even as a superhero in his own world, because all he did was get thrashed around by every major villain that he faced.
This is why when he’d be faced with supernatural entities in the Jujutsu Kaisen Universe, he’d be no match for them because while he may be a good fighter when it comes to hand-to-hand combat, he would be completely defenseless against cursed energy.
2 Would Survive: Emilia Defeated Satan Himself (The Devil Is A Part-Timer)
The King of Curses, Sukuna (who resides within Yuji's body), is the most powerful creature in his universe, but despite all his power, he still is just a cursed spirit who is absolutely no match for the unimaginable powers of the Demon King himself.
So if the half-angel Emilia was able to not only impale Lucifer but push back all of Satan’s army to the point where the Demon Lord was forced to escape to earth, it stands to reason that the divine sword she used in battle would easily be able to slice through Special Grade cursed spirits like butter.
1 Wouldn’t Survive: Ai Only Has Powers Inside The Egg World (Wonder Egg Priority)
Even in the Egg World, her powers were limited, and even assuming she’d somehow manage to bring those powers to a new world, they would be completely useless when fighting cursed spirits.
Not to mention that someone as emotionally fragile as Ai would easily be manipulated by Mahito (exactly what he did with Junpei), with her becoming a cursed user who’d eventually be killed by Mahito out of sheer boredom.
