Pirates / Marine themes?

So, ever since I was a kid, I've always loved the ocean, the life in it, and pirates.

Graves was already one of my favorite champs, and now with the Cutthroat skin I bought a few days back, he's my new main jungler (until Jhin comes out anyway...). So, I was just wondering, are there any more champs / skins with that more marine / pirate feel? MF, Naut, GP, and so on are all obvious, but are there any that I don't know about? :3

And, hey, Riot, you should make more marine skins, like, I could Vel'koz being an angler fish, since they have all those warbles (tentacle-y things) on their face, and his eye can be the light. :P
