Part of what makes it so difficult to parse out who might win between All for One and Sukuna is the fact that their powersets are so different. Furthermore, it can also be tough to keep track of All for One’s massive moveset, one that’s made up of over a dozen combined quirks. Looking at a list of his powers, it would seem that Hypertrophy, Super Regeneration, and Air Cannon would be quirks that could give him an edge.
Meanwhile, Sukuna also has quite a bevy of powers to choose from, though in his case, they’re supernatural. In his corner are lofty moves like Reverse Cursed Technique, Malevolent Shrine, and the absolutely brutal World-Splitting Slash, which was used to one-shot one of the series’ strongest characters.
Though Sukuna from Season 1 of “Jujutsu Kaisen” going up against a Season 3 All for One from “My Hero Academia” could be an exceptionally close fight, Sukuna’s abilities have tripled since then. Now, having swallowed 15 out of 20 fingers, Sukuna has become exceptionally dangerous.
Though there’s still an argument to be made in All for One’s favor, especially considering the ingenious ways that he combines his quirks, the current version of Sukuna would obliterate any version of All for One that we’ve seen, and that pretty much settles it as far as our money is concerned.
