Yeah...Oda ruined Sanji...
So the moral of the story is, take drugs kids, modify and get random DNA to enhance yourselfs. Don't be human kids!
Nice writing Oda lmao - what kinda BS is that?
He actually didnt ruin anything, Sanji's progress is exactly as expected.
He doesnt have a DF like Luffy to get stronger by developing its abilities.
He isnt training like Zoro is nor does he use dangerous weapons.
The guy who does nothing and the fandom that wants him to be like Zoro...
That's where the problem lies. The power-ups have to come from other sources.
That's why you have family tech coming to his aid, because he himself isnt doing anything about it.
