The Jujutsu Kaisen Cursed Techniques showcase incredible supernatural abilities through their diverse range of users. These powers often mirror the creative potential found in One Piece's Devil Fruit system. Many Jujutsu Kaisen Cursed Techniques possess the same reality-bending properties that would fit perfectly within the Grand Line's chaotic seas. These could easily translate into Paramecia, Logia, or Zoan-type Devil Fruits.
1. Teleportation Devil Fruit (Boogie Woogie)

By clapping his hands, Aoi Todo activates an ability that instantly exchanges the locations of people or items within his reach. As a Devil Fruit, it would resemble the Room abilities of Law, but faster and less energy-draining. This Paramecia-type fruit would instantly allow users to exchange locations with any target possessing spiritual energy.
This Jujutsu Kaisen Cursed Technique could transform naval combat entirely. A pirate could infiltrate ships, dodge point-blank hits, or save crew members instantly. It’s perfect for a chaotic, high-speed One Piece fight scene.
2. The Faith-Faith Fruit (Miracle Creation)

Kinji Hakari’s technique activates a jackpot on a pachinko machine that grants temporary immortality and super-regeneration. In One Piece, this would be a Paramecia-type Devil Fruit that gives users random buffs or invincibility when lucky conditions are met.
It’s one of the riskiest Jujutsu Kaisen Cursed Techniques, but in One Piece, it would turn the tide with pure chance. Imagine a pirate who keeps gambling mid-fight for a shot at invincibility. It adds unpredictability and casino-style tension to high-stakes battles.
3. The Blood Control Fruit (Blood Manipulation)

Noritoshi Kamo and Choso’s Blood Manipulation grants full control over blood, solidifying, weaponizing, and even healing with it. As a Paramecia-type Devil Fruit, it would allow users to weaponize their own blood or others’, creating deadly spears or blood armor.
This is one of the most stylish Jujutsu Kaisen Cursed Techniques, and it fits the One Piece aesthetic flawlessly. Think of a user slicing themselves just to form blood blades mid-air. It combines grit with elegance—ideal for both anti-heroes and tragic backstories.
4. The Mimic-Mimic Fruit (Copy)

Yuta Okkotsu’s Copy technique allows him to replicate other cursed techniques after experiencing them. As a Devil Fruit, it would resemble the Copy-Copy Fruit—a Paramecia that lets its user mimic any Devil Fruit power they've seen, but only temporarily.
Among the many Jujutsu Kaisen Cursed Techniques, this one stands out for its adaptability in combat. In One Piece, it would make the user an unpredictable wildcard, able to mimic Luffy’s rubber body or Akainu’s magma fists for a short time.
5. Soul Shaping Devil Fruit (Idle Transfiguration)

Mahito’s cursed ability manipulates the soul’s structure directly, allowing him to distort or alter a person’s physical form through mere contact. Translated to One Piece, this could be a Paramecia Devil Fruit that allows the user to alter not only their form but others’ as well.
Among Jujutsu Kaisen Cursed Techniques, this one is body horror at its peak—perfect for the morally grey villains of One Piece. It could also offer regeneration or grotesque body modifications in combat, giving the user a monstrous edge.
6. The Gag-Gag Fruit (Comedian)

Takaba’s power turns his jokes into reality—if he truly finds something funny, it can actually happen. This would be a bizarre and unpredictable Paramecia-type Devil Fruit. It will give reality-warping abilities if the user genuinely finds a situation hilarious.
Among all Jujutsu Kaisen Cursed Techniques, this one is peak chaos. In One Piece, it’s perfect for a gag villain—or even a comedic hero like Franky or Buggy. One joke could turn the tide of battle, as long as the user laughs hard enough.
7. The Command-Command Fruit (Cursed Speech)

Toge Inumaki’s cursed speech forces anyone who hears his words to follow them. If this became a One Piece Devil Fruit, it would be a Paramecia-type ability allowing vocal commands to control others' actions—similar in function to Boa Hancock’s Mero Mero, but far more versatile.
Few Jujutsu Kaisen Cursed Techniques are as instant and effective as this. With one word, the user could end battles, cause mutinies, or escape Navy sieges. It’s a subtle power, but one that could easily tip the balance of any fight.
8. The Slash-Slash Fruit (Shrine)

Sukuna’s Shrine unleashes a relentless wave of cursed slashes across a defined area, requiring no barrier to activate. Reimagined as a Devil Fruit power, it would produce a deadly zone where all within are carved apart indiscriminately by invisible blades.
This Jujutsu Kaisen Cursed Technique is pure destruction—relentless, precise, and unstoppable. A user could obliterate entire fleets or towns with a single activation. It’s the kind of Devil Fruit ability that would instantly terrify both Marines and pirates alike.
9. The Verdict-Verdict Fruit (Judgeman)

Hiromi Higuruma’s Judgeman invokes a courtroom where enemies are judged based on their actions. If turned into a Devil Fruit, this would be a Paramecia-type that traps enemies in a trial zone. If found guilty, the target temporarily loses their abilities or gets sentenced to a random punishment.
Exceeding all Jujutsu Kaisen Cursed Techniques, this one brings a legal twist to combat, adding a layer of mind games. In One Piece, it could strip a Devil Fruit user of their powers temporarily, making it a terrifying countermeasure. It also fits perfectly with characters like Sengoku or the World Government.
10. The Frame Freeze Fruit (Projection Sorcery)

Naoya and Naobito Zen’in’s ability freezes motion by breaking down time into 24 frames per second. In One Piece, this would be a Time-based Paramecia Devil Fruit allowing frame-by-frame control of motion, basically creating freeze-frame moments mid-battle.
Among Jujutsu Kaisen Cursed Techniques, this one offers a stylized, cinematic flair perfect for One Piece’s dramatic battles. A user could teleport frame-by-frame, or slow enemies without them even realizing it. It’s flashy and cool.
In conclusion, the wild creativity behind Jujutsu Kaisen Cursed Techniques shows just how well these powers would translate into the Devil Fruit system of One Piece. These abilities would be right at home on the Grand Line. And in a crossover universe, they would dominate the seas.
