What if Monkey D. Luffy from One Piece were to go up against Satoru Gojo from Jujutsu Kaisen? The answer has been debated upon by many anime fans for a while now. The reason this fight would be interesting is that both these characters have very different abilities.
Protagonist One Piece—Luffy—is blessed with supernatural reflexes and force, the power of Gomu-Gomu no Mi, which allows him to exercise his body like rubber. Whereas in advanced forms, such as Gear 5, he could perform even more spectacular things. On the other hand, Gojo from Jujutsu Kaisen is a mighty sorcerer. It's known that he has the Limitless Cursed Technique along with the Six Eyes, so that makes this character close to impossible to defeat.
Many fans argue on different online forums that this battle would end up in a stalemate. Another reason would be Gojo's Infinity technique, which births an infinite space between himself and any attack. This literally makes it impossible for any sort of physical attacks to reach him. There is no doubt that this guy would prove to be a headache for Luffy, whose combat mainly consisted of pure physical strikes.
The strength of Luffy, however, lies in close-range fighting. Some folks argue that he will triumph over Gojo in hand-to-hand fighting. Moreover, Luffy's speed can be viewed as another deciding element in his favor since many sources say he might be faster than light.
Despite the really cool abilities Luffy has, his attacks won't have any action against Gojo because of the Infinity barrier. One fan points out that for Luffy to hit Gojo, he would have to bypass the Infinity, which, given the nature of his abilities, is highly unlikely.
On the other hand, his durability seems rather impressive on the defensive side. After all, attacks by Gojo aren't exactly known for their destructive capacity, so they might not be enough to inflict major damage on Luffy. He may just have enough durability to take a few of Gojo's jutsu, including his Domain Expansion.
Haki, One Piece's version of Chi or life energy, makes for an interesting concept regarding Luffy. Fans are speculating how much more advanced forms of Haki Luffy possesses, mainly his Observation Haki or Conqueror's Haki, can work like Domain Amplification in Jujutsu Kaisen and allow him to interact with Gojo's Infinity. Again, it remains speculation.
The other challenge Luffy would have to face would be Gojo's healing. Even if he could connect with an attack, given Gojo's healing from grievous injuries, it would be hard for Luffy to inflict a decisive defeat on him.
Some say that without infinity, Luffy could possibly win against Gojo. But that is a bit of a 'what if', seeing as technically, Infinity isn't supposed to leave Gojo.
This would mean Luffy's "limited Toon force" wouldn't be enough to get past Gojo's defenses. The Infinity barrier would make it impossible for Luffy to make physical contact, which is needed to apply those rubber-like properties on enemies.
While Luffy has the strength, speed, and durability that are truly inhuman, Gojo's Infinity technique makes him very hard to defeat, arguably impossible. So, the general consensus for this fight would be a draw, neither able to defeat the other because of the nature of these abilities and defenses.
