How dafuq can we know?
100% 50% 30% 120%.
This isn't a fucking video game.
This back and forth of weird ass healings, magical potions, etc is completely BS. It's "luffy eats than comes back to full" level of nonsense. It's part of One Piece.
We don't know how badly injured they are, or how much it affects their "stats". We don't have "menu" button to click and check the characters stats at every page.
This % debate is one of the most retarded things that this fandom war ever created.
Oda gives 0 fucks about "damage". The way he approaches it is amateur level. Any sports or fight mangaka does a better job at exploiting injuries and how they affect the performance of a fighter. And in high fantasy shounens like One PIece, we also have people that are better at it than Oda, like Togashi. Just look at Jinbei fight against Whoswho. That is, by far, the greatest offender so far on this raid. We have Whoswho pushing Jinbei back the entire fight, than, OUT OF FUCKING NOWHERE, Jinbei basically feels NOTHING. >>>>>NOTHING<<<<< from Whoswho attacks and then fuck him up. That's the most BASIC and VANILLA type of "shounen trope" ever. The "gets beaten all fight long, than gets pissed and win" reverse sweep.
Fuck these % stuff.
