During Sukuna VS everyone, Sukuna was able to land 4 Black Flashes boosting all his stats. Due to this, Sukuna was now in an Awakened State & became a busted Gary Stu (can use any CT/vow).
[Narrator: Just like Satoru, through successive black flashes, The King of Curses restored his busted RCT, now entering a high, omnipotent-like-state.]
Heian Sukuna: makes a hand sign eerily similar to Gojo’s Infinite Void!
“DOMAIN EXPANSION: MALEVOLENT SHRINE”
The King’s Domain returned to its master… in a shower of black sparks.
The guaranteed hit activated & you were slashed numerous times, almost to death.
[Narrator: Unbeknownst to everybody, Sukuna had placed numerous binding vows on himself & imposed a secret trump card binding vow on himself after he killed Gojo: Being able to use & upgrade Satoru Gojo’s CTs—The Limitless , the Six Eyes & even his own version of DE: Infinite Void!]
Heian Sukuna: “Hehehe. Seems my gamble paid off. Now then…” He looked at you with a devilish smirk, readying to finish you off
“Divine Flame! Open!”
[Narrator: Sukuna entered into another one of his many impromptu Binding Vows. To make Divine Flame more effective, Sukuna can’t use Divine Flame when he’s outnumbered unless when his Domain is open. Due to this Binding Vow he can expand the cursed technique of Malevolent Shrine, and all pulverized substances gain explosive cursed energy. Furthermore, he created a seal within the effective range to prevent any escape without lowering Malevolent Shrine’s output.]
[The particles that have become thermobaric explosives scatter to every corner of the domain. The heat from Divine Flame causes detonation, instantaneous high temperature, shockwaves, decompression, and intense pulverization which in turn KILL all living things within the domain. In Shibuya, Ryomen Sukuna used this, his ultimate secret art to defeat Mahoraga in one blow.]
Heian Sukuna: “Heh brat…” Uses Dismantle & slices your hand clean off.
[Narrator: Sukuna is a brilliant sorcerer, possessing a deep & vast understanding & knowledge of cursed techniques, curses, binding vows (Binding Vow Merchant), cursed tools, & RCT, including where precisely the part of the brain that supports domains is located. His "Strongest Sorcerer in History" title reflects his unparalleled ability with Jujutsu. He is able to utilize Mahoraga to allow for more strategically effective attacks against Gojo by using him to bypass Infinity. Sukuna constantly switched between Domain Amplification and an innate technique, to which Kashimo had claimed that if Gojo did not have the Six Eyes, Sukuna's Cursed Energy control would likely exceed his. Sukuna's ability to quickly deduce & counter cursed techniques is unparalleled, as seen in his battle against Mahoraga in which he solved how his adaptation worked, surpassing the previous wielder of the Six Eyes and the Limitless, who was defeated by the Shikigami. Even when completely overwhelmed by Gojo in their first meeting, Sukuna quickly began deducing the nature of the sorcerer's innate technique, being implied to be aware of Gojo's enhanced punches. Even Satoru Gojo, the strongest jujutsu sorcerer of the modern age & a natural genius himself, acknowledges Sukuna's formidable skills as a sorcerer. In his battle with Gojo, he began to see how Mahoraga adapted to Gojo's Infinity and used Mahoraga as a baseplate to create a technique to bypass it, achieving a feat he never thought was possible with his Cursed Technique in one try—courtesy of the model given to him by the Shikigami—while also using a binding vow that allowed him to cast it with no hand signs. He copied the concept of soul splitting from being turned into a cursed object by Kenjaku, and the ability to refresh his cursed technique burnout after only seeing Gojo do it once (copied Gojo’s RCT feat). Sukuna holds the strongest Domain Expansion in the entire verse, having an Open Barrier Domain with power superior to that of Kenjaku, a feat known to be divine.]
