Ryomen Sukuna—the King of Curses—isn’t just the most terrifying being in the Jujutsu Kaisen universe, he’s the embodiment of chaos and cruelty itself. With a smile as sharp as his cleave and a laugh that echoes through corpses, Sukuna dominates not just with power but with pure sadism. There’s no redemption arc. No tragic backstory to soften his edges. Sukuna exists to destroy, and he enjoys it. His presence is a constant reminder that curses don’t play by human rules—and neither does he. Whether he’s eviscerating enemies, taunting allies, or casually committing mass murder, these are the Top 10 Most Ruthless Sukuna Moments That Prove He’s the King of Curses—long live the tyrant.
#10: Sukuna Slaughters the Finger Bearer Instantly
When Yuji is forced to consume a cursed object—a Sukuna finger—he unknowingly awakens the monster within. In their first major test against a special grade curse at the detention center, Yuji, Megumi, and Nobara quickly find themselves overwhelmed. But when Sukuna takes over Yuji’s body, the entire tone of the scene shifts. What was once a horror movie turns into a slaughter. Sukuna toys with the Finger Bearer—mocking its strength, regenerating from wounds effortlessly, and ultimately slicing it in half without using his full power. What makes it so brutal is the boredom in Sukuna’s voice. He’s not trying. He’s playing. And his ability to casually dismantle what terrified the others cements the hierarchy: Sukuna isn’t just a curse—he’s the top of the food chain.
#9: Sukuna Forces Yuji to Swear an Unbreakable Vow
After reclaiming control of Yuji’s body during a near-death experience, Sukuna doesn’t kill him—instead, he makes a deal. But not a fair one. With a smile, Sukuna tricks Yuji into swearing an unbreakable vow—allowing Sukuna to take control for one minute when he says a specific word. And the best part? Yuji won’t remember making the deal. It’s manipulative, one-sided, and cruelly brilliant. This is Sukuna at his most insidious. He doesn’t just destroy with power—he undermines his host with mind games and magical contracts. It’s psychological warfare, and Sukuna plays it better than anyone.
#8: Sukuna Slays Mahoraga with Divine Disrespect
In one of the most technical and awe-inspiring fights in the series, Sukuna is forced to deal with Mahoraga, the most powerful Shikigami of the Ten Shadows technique. Summoned by Megumi (with plans to die in the process), Mahoraga adapts to any attack, making it seemingly invincible. But Sukuna sees it as a challenge—and a chance to play. What follows is a clash of titans: a cursed king versus a divine beast. Sukuna unleashes his full arsenal, including his domain expansion “Malevolent Shrine,” slicing through space with Dismantle and Cleave techniques.
Despite Mahoraga adapting, Sukuna learns faster. He manipulates attack angles, delays his strikes, and times his cleaves so precisely that he ends the fight with surgical perfection. It’s not just victory—it’s domination. And the moment Mahoraga falls, Sukuna turns with a smirk and says, “That was fun.” The sheer savagery of enjoying a battle that nearly cost him everything makes the win feel all the more terrifying. He doesn’t just survive impossible odds—he makes art out of destruction.
#7: Sukuna Forces Yuji to Watch a Massacre
Possibly one of the most haunting moments in the series, and the one that truly shatters Yuji’s soul. After switching back into control during the Shibuya Incident, Sukuna unleashes his Malevolent Shrine domain expansion over an entire city block. He obliterates curses and humans alike in a 140-meter radius, slicing everything—people, buildings, and allies—into unrecognizable gore. What makes this worse is that when Yuji regains control… he sees the bodies. He sees the blood. And he realizes that his body—possessed by Sukuna—did it all.
Sukuna doesn’t just kill. He kills in your body, with your hands, and then lets you wake up in the aftermath. It’s cruelty on a cosmic level. Not only is it one of the most devastating attacks in the series—it’s one of the most sadistically personal things Sukuna has ever done. And he does it all with a grin.
#6: Sukuna’s Execution of Jogo—With a Compliment
Sukuna and Jogo, both special-grade curses, finally clash in what begins as an overwhelming flex. Jogo unleashes his flames, his meteors, and his full cursed energy arsenal. Sukuna responds… by laughing. He’s so unimpressed by Jogo’s attacks that he lets himself burn, just to prove it doesn’t hurt. When he does start fighting back, he absolutely humiliates Jogo—ripping him apart, blasting him through terrain, and outpacing him at every step.
But the most chilling part comes at the end. As Jogo lies dying, Sukuna gives him a rare compliment: “Compared to the rest of them, you were strong.” Then, without a pause, he incinerates Jogo’s head. It’s merciful in the most twisted way—because to Sukuna, mercy is still death. That cold, casual acknowledgment of Jogo’s strength makes the kill even more ruthless. He’s not angry. He’s not excited. He’s just cleaning up.
#5: Sukuna Sacrifices Yuji’s Body to Summon Mahoraga
In a moment that redefines cruelty and tactical genius, Sukuna uses Yuji’s body—without his consent—to summon the forbidden shikigami Mahoraga via the Ten Shadows Technique. Why? Not for survival. Not even for power. Simply to test it. Megumi had initiated the ritual and was about to die doing it, so Sukuna hijacks the summoning… and lets Mahoraga fully manifest, knowing the price will be mass destruction. He then proceeds to fight Mahoraga just for fun, using it as a sparring partner to refine his own techniques.
But here’s the real horror: Sukuna ensures Yuji experiences the aftermath—waking up in his body surrounded by dozens of dead civilians, with Mahoraga’s path of destruction leaving the city in flames. Sukuna doesn’t just kill. He engineers guilt. He weaponizes it. This is Sukuna playing chess while everyone else is playing checkers, and the board is painted in blood. It’s not just ruthless—it’s genius-level sadism.
#4: Sukuna’s Possession of Megumi
One of the most shocking and soul-crushing moments in Jujutsu Kaisen is when Sukuna decides to possess Megumi Fushiguro. It’s the culmination of an obsession he’s hinted at for a long time—Sukuna sees massive potential in Megumi’s Ten Shadows Technique, and when the opportunity presents itself, he takes it. Sukuna uses a Binding Vow and Yuji’s moment of weakness to sever his connection with his former vessel and invade Megumi’s body completely.
This isn’t just a body swap—it’s identity theft at a spiritual level. Sukuna desecrates Megumi’s will, uses his techniques more efficiently than he ever could, and twists his body into a killing machine. He even kills Megumi’s sister Tsumiki while controlling him, ensuring that Megumi, buried somewhere deep inside, feels every second of it. The possession isn’t just about power—it’s about desecration. Sukuna steals not just the body, but everything that made Megumi human.
#3: Sukuna vs. Yorozu – A Ruthless Dissection
Possessing Megumi’s body, Sukuna confronts Yorozu, a reincarnated sorcerer who is obsessed with him to the point of insanity. But Sukuna doesn’t return the sentiment—instead, he treats her like an experiment. Yorozu throws her full power at him, using structural flesh techniques to form an ever-shifting armor and domain. Sukuna calmly counters her with the fusion of Mahoraga and Nue, a monstrous construct born from Megumi’s potential. The battle is utterly one-sided.
Sukuna never breaks a sweat. He methodically breaks down her technique, dodges every strike, and finally kills her—not with rage or struggle, but with surgical coldness. Even in death, Yorozu’s final words are a twisted love confession. Sukuna’s response? A blank stare. No emotion. No acknowledgment. He just walks away. It’s the emotional void of the moment that makes it so brutal—he kills not out of hatred, but because it’s inconvenient to let her live.
#2: Sukuna vs. Satoru Gojo – The Fall of the Strongest
In what is perhaps the most hyped and devastating battle in the entire series, Sukuna takes on the strongest sorcerer of the modern era: Satoru Gojo. The battle is cosmic in scale—domains crash, cities shatter, cursed energy warps space, and for a while, it seems like Gojo might win. But then Sukuna outplays him. Using a clever misdirection involving Domain Amplification, Cleave’s adaptability, and Mahoraga’s mimicry, Sukuna adapts to Gojo’s Infinity and lands a fatal blow.
He doesn’t just defeat Gojo—he cuts him in half. The fan-favorite, the indomitable mentor, is killed in a blink. Sukuna doesn’t gloat. He doesn’t scream. He just affirms what he’s always known: he is the apex predator. This wasn’t about proving himself—it was about removing a threat. Gojo’s fall isn’t just a plot twist—it’s a statement. Sukuna didn’t win because he was stronger. He won because he learned faster. And that’s far more terrifying.
#1: Sukuna’s Domain Expansion – Malevolent Shrine
If there is one moment that embodies Sukuna’s absolute, God-tier ruthlessness, it’s the unveiling of his Domain Expansion: Malevolent Shrine. Unlike traditional domains that require a barrier, Sukuna’s is so complete that it doesn’t even need walls. It naturally manifests, expanding over a 200-meter radius where everything is slashed, indiscriminately. Buildings. Curses. People. Everything is diced at the molecular level.
When he activates Malevolent Shrine during the Shibuya Incident, the city block turns into hell. Bodies are split before they hit the ground. Screams are cut short by physics-defying blades. Sukuna doesn’t even need to look at his victims. His Cleave technique adapts to durability, slicing everyone perfectly in one motion. It’s power without equal—cold, calculated, and horrifyingly beautiful. This is the moment that fans and characters alike realized: Sukuna isn’t just the King of Curses. He’s an extinction-level event.
Sukuna isn’t just ruthless—he’s the blueprint for domination. Whether he’s carving through cities, tricking his host, or casually humiliating enemies, every move he makes is a reminder that in the world of Jujutsu Kaisen, fear has a name. And that name wears two faces, four arms, and a smile you never forget. The King of Curses doesn’t just fight battles—he leaves legacies of horror in his wake.
