JoyboyA One Piece inspired Mythology

(First and foremost, let me state that, no, this does *NOT* contain any spoilers about One Piece besides the name. In fact, only 2 One Piece figures are mentioned in this mythology. I myself detest manga spoilers; I wouldn't do anyone dirty like that. Now for the reason why I made this and what it's about: )

I heard that Joyboy is an actual legend from South American/Jamaican mythology that inspired Oda (the author of One Piece), along with Tom and Jerry and other sources. A warrior who was a champion of the slaves, as he set them free and blessed them with freedom. I wanted to see what the original Joyboy was like in our Earth's mythological history of him. However, try as I might, I could not find any stories that mentioned a Joyboy or Nika or a warrior of liberation. I'm not sure how Oda came across the legend/mythology, but I am forever beyond grateful that he did. But grateful as I am, that left me slightly unsatisfied. So, I decided to write Joyboy as a mythology story myself, like the ones from Greece, Egypt, Norse, Hawaiian, African, etc., that we read in class. My language may need some work, but this is how I believe Joyboy's mythology would be told if he had the same recognition as Percious, Horus, Thor, Anansi, Moui, etc.
It is my deepest wish and hope that either lots of people who never watched/read One Piece enjoy this and remain spoiler-free, One Piece fans get a kick out of this, and potentially that Oda himself will take/find amusement in this attempt at literally writing history.
