Sigh.., if Oda really gonna do that.., smh.., this is why I dislike One piece in this particular matter, luffy is just a teenage kid, while he's undoubtedly been through hard battle and shit, there's no way that's comparable with these adult monsters had been through, in fact he's growth rate is really absurd to begin with, he's like what..?, 18?, while... god knows for how long and hard katakuri(40s) had trained to achieve FS, and what luffy had to do is just eat some punches and kicks.., basically stalling him long enough and suddenly he started to develop the same shit..?, really..??, I know he's the MC, so oda gotta make some shit up for these kids/audiences to jerk off for.., but I personally hate this kind of asspull..
