"Luffy gets himself stuck under a disadvantage before finally turning up for the big fight against the arc's villain"

Every movie or TV show that involves the main protagonist fighting against the main antagonist before the climax will have the protagonist at a major disadvantage or losing the fight. This will cause the hero to build the strength back up so the audience will root for him even more when the final fight actually does come.
