Kizaru is making G5 look overrated honestly, let alone Luffy.
Idk if it was the new mode effect, but G5 looked like a problem against Kaidou...how tf is someone who isn't even supposed to be a tank looking so unfazed by such a juiced up attack to the head?
If this fight is any indication, Kaidou is indeed getting powercreeped to oblivion by EOS, like any series the first showcase of a powerup will always look more impressive, each subsequent use of G5 is gonna become more of a norm.
