@Monkey:
I doubt Oda's read that specific book, he doesn't come off as a studied Hero's journey scholar so much as someone accustomed to the associated cliches through experience of reading and watching a shitload of movies and comics.
One Piece is a hero's journey story, but it's not one that really follows the Campbell model much at all. The Campbell model assumes an everyman (at the start) hero.
No, it doesn't follow it, but I believe there are parts of the story we could match with specific steps of Campbell's models.
These steps being: "crossing first threshold"; "belly of the whale"; "atonement with father (= training with Rayleigh)"; "the ultimate boon(? (him being pirate king)); "freedom to live(? what happens after he becomes pirate king)"
Interrogation signs for events that could happen in the future.
It's probably due to the fact that this is an adventure manga in which we follow the quest of a hero, more than Oda being inspired by Campbell directly. Yet I find the Laboon "arc" curious, as it really resembles the "Belly of the whale" step and happens… inside the belly of a whale. There aren't much coincidences (if not at all) in the plot of a fictional story. I don't think this was either.
@Monkey:
-The "first threshold" suggests leaving the peaceful starting zone, which in actual Campbell meaning is literally a safe place where little to no adventure stuff can happened. So Luke leaving the farm, Bilbo and Frodo leaving the Shire etc. So suggesting that crossing the Red Line is the first threshhold for Luffy is….really hard to defend. By that point Luffy had fought a bunch of death battles in a variety of adventures and risky situations. The Grand Line is a major leap in danger, but the dangerous outside world is already being traveled in.
The first threshold would correspond to him leaving Foosha village for the very first time, aged 17.
He leaves a peaceful village to sail on a sea he doesn't yet know. It's also the beginning of his long adventure.
@Monkey:
And I gotta come back to that everyman thing, the whole Campbell model really HAS to have an everyman. We have to watch some Joe Schmo nobody who could be anybody, transform from a wimpy rookie…into a wise badass.
And this just does not apply at all to Luffy. He was a super driven fire cracker from the start, we saw him being more vulnerable in the Ace/Sabo flashback sure, but that's the extent of it. And of course the everyman hero is a hero who we travel AS, we embody them because they're relatable people who we "get" and understand the background of.
Luffy is a mysterious simpleton of enormous drive, whose past we keep learning more about, past that he KNOWS that we had no clue about. And a character who has never once received any internal monologue.
We are in the adventure WITH Luffy, not ever AS Luffy.
I'll have to agree on some parts of this - however I do not think his care-free personality changes the fact that he was just an unknown child setting out on an adventure at the beginning of the story.
I don't understand the distinction you make between him and Luke/Bilbo/Ishmael (Moby Dick), characters that indisputably follow this model.
Is it because we can't relate to Luffy as much as we do to these characters due to him being "surhuman"? Luke Skywalker mastered the force; he was surhuman in a way, having a greater potential than most humans.
Or is it that Luffy is more "special" in a way? If yes, in which way?
@Monkey:
And of course the everyman hero is a hero who we travel AS, we embody them because they're relatable people who we "get" and understand the background of.
Luke Skywalker's background was explained in greater depth later on in the story, with Vader revealing that he was his father. It's like Luffy, in a way; we don't get to know his whole background from the start.
@Monkey:
You'll see how Usopp's storyline in the Kuro arc (and hell in some ways thus far his whole storyline) actually fits Campbell's model much better.
I'll read this arc again having this idea in mind then.
It would make perfect sense, as Usopp is a character we readers are meant to relate to most (if I remember correctly, Oda himself has stated this) - the only "normal" human (with "normality" being what it is in the OP-verse) of the entire crew.
@Monkey:
tldr: I don't think Oda based Laboon off that
In your post you said that "One Piece" as a story doesn't follow Campbell's model, but Laboon being a reference to/following one particular step remains a possibility.
