One Piece name generators

One Piece is an incredibly popular manga series with an equally popular anime production. The manga started in 1997 and, at the time of writing this, is still ongoing. Between 2008 and 2018 it was the best-selling manga and is the only manga that has sold over 1 million copies of each of its over 100 volumes (tankōbon).
The anime started in 1999 and is still ongoing as well. In combination with movie adaptations, variously tv specials, a huge amount of merchandise and more, One Piece is an entertainment franchise with revenue in the billions, surpassing the likes of James Bond, Warcraft and Final Fantasy.

The story follows the adventures of Monkey D. Luffy, a boy who gained powers from a devil fruit (a magical fruit), turning his body to rubber. He uses this elastic power to his advantage as he tries to fulfill his dreams of becoming a pirate by sailing the world, sailing the seas with his crew to aid those he can or fight those who get in his way.

I've created 5 name generators for various elements within the One Piece universe, as you'll see below. So there's a fair chunk you can work with should you need names for fan-fiction or other, similar types of work.
