i think it was someone in the sea that the story originated from which i think was east blue. So im thinkin don krieg, and axe hand morgan. It als o could have been someone from the cover art stories. it realized that they are also cannon to the story. I didnt think that those stories meant anything but apparently my friend pointed out to me that the mermaid chick was actually in a previous cover art with hatchi. The cover art showed them opening the taiyoki shop. i went back and saw that some of crocodile's team broke out too. i didnt read the manga from the jump so i feel like i missed like a thrid of the story. Long story short it could be morgan kreig or someone easily overlooked.
