@Mpwilson123 You understand that's how a fantasy story works, right? You think you're opening your eyes to some similarities between a story but go and keep following your train of thought real quick.
Pirate Sorcerers = Good guys
Marine Inquisitors = Bad guys
Water air = Literally the world.
Devil fruit infections = super powers
water prism stone silver = Counter to super power plot device
Mc has a mysterious brother = Mysterious past plot device
It's not the first time this story was told, it's not going to be the last time you see it either. Don't get caught up in avoiding cliches if you're going to intentionally the joy of a story out of it for yourself. Worry more about the world building, the character's personalities, how the super power system works, the character development, and plot if you really want to poke holes.
