A half dead Luffy who could barely use Haki isn't overpowering something even Jozu couldn't; nothing even suggests G4 increases Luffy's raw physical stats to begin with. Luffy's sudden transformation is what caused Parasite to break and Zoan's can shape-shift easier than Luffy.
Can I ask something?
why do people assume Jozu couldn't break out of Parasite? when we CLEARLY saw Parasite can only be:
1- Broken by force like Luffy
2- Inactivated by Doffy himself
because Crocodile doing sables wouldn't make Jozu break out of it... because we SAW THAT ALREADY when Bellamy couldn't break out even though he's far away, on a different floor, and Doffy is busy fighting Law
How about the tons of citizens who also Doffy controlled? again
the mechanism of that move is not so simple that Jozu was saved by Crocodile sables LMAO
Jozu simply broke out of it by himself, HOW? Oda just skipped it, as simple as that... why did Jozu hang around listening? cause Japanese anime characters loves to do that LOL, they just hang around, hold back until they reveal some shit
