Well, infinity works by sensing things with cursed energy, shape, speed and Mass, so, things that lack mass such as sound, light etc can bypass infinity, does Nagato have some attacks that doesnt have mass? I was going to say the gravity attacks, but not sure
For the record, lacking mass is not enough to bypass Gojo’s Infinity. The feats for his Infinity proves otherwise.
Gojo’s Infinity has shown to block one of Jogo’s attack, which outright uses a sound-based attack (The anime version of the scene also shows the environment behind Gojo being damaged by the sound, which I assume can be treated as valid since one of the JJK Threads mentioned that the JJK anime has the author’s storyboards given to them to make the anime, along with the manga also mentioning sound as a form of attack that Gojo is equally unaffected by. The attack is also mixed with an explosion-based attack as it’s a “two-pronged strategy of sound and explosion”, but the explosion aspect is irrelevant).
Gojo also implied that none of Jogo’s heat-based attacks worked against him due to his Infinity (since none of them “hit him”) before the moment Jogo used his Domain Expansion, which implies that heat shouldn’t work against Gojo either due to his Infinity as well and not just because of his resistance to heat. Heat does not have mass, and yet Gojo is capable of blocking them.
Since I doubt sound or heat truly has mass or shape, mass and shape shouldn’t be a requirement for Gojo’s Infinity blocking attacks without them (although attacks that have them will definitely help in being factors for Infinity to stop them). The only requirement Gojo’s Infinity has not shown to block without is speed/velocity, since every attacks Gojo’s Infinity has blocked involves crossing a distance in one form or another, so speed/velocity is the only aforementioned true requirement that’s needed for Gojo’s Infinity to block, since all the other three (mass, shape, cursed energy) has shown to not be required for his Infinity to stop.
I’m not sure about light or gravity, but sound and heat (and having mass as one of the requirements needed for Infinity to block attacks) is not enough to overcome Gojo’s Infinity as Infinity blocked both of them (which, again, has no mass, especially in the case of heat).
As for Pain’s wincon, I think it’s when he waits for Gojo to touch his hand (like Gojo does to Jogo) and then activates human path via soul-ripping (which if I recall correctly, Mahito’s feats of spiritual attacks doesn’t quite encompass as it’s all soul-alteration or soul-merging) the moment physical contact is made?
Not sure how likely that is, but it’s not impossible I guess.
