My man in christ you talk about plot armor and bs tropes (without mentioning them, and bs tropes encompasses power up for shonen, but I guess that you are just randomly spouting buzzwords now) but are a fan of a walking trope yourself, so much that you identify as him making him your propic and name on a forum.. You know Zoro is not real, right?
I don't know why 5 is a relevant number, but every important fight Zoro has with a non-fodder he awakens a new power, it happens with Kaku out of nowhere, with King and and with mr.1, again out of nowhere for mr.1.
At least in Luffy v Katakuri you see Luffy trying to learn it from Katakuri himself.
I don't understand why Luffy winning a battle of principle with the best choreography so far in the manga is such a problem for you.
And again, Luffy "did not win".
Don't you guys ever get tired of saying that Luffy never wins his fights?
