One Piece: Chaos Kong

Meet Jason, soon to be a widely known infamous pirate called Diddy D. Kong, but before we get that far, let's rewind time a few hours.
Jason was just your everyday man, maybe not every day, as he was a large man covered in muscles, infatuated with the concept of strength; however, before he could achieve his dream of becoming the strongest, he died of a heart attack in his sleep, though, luckily for him, that wasn't the end as he was reborn in a world where chaos runs rampant in the form of pirates. Now born in a world where his dream of becoming the strongest is achievable, watch as he slowly carves his way to the top in the body of a powerful race, along with help from some friends that'll accompany him on his journey.
