Maybe it's just as simple as him feeling sorry for them 'cause they were already injured iunno, or maybe he's upto something with Garp. Funny how alot of the female characters looks exactly like Nami but with different hair or something. It's typical of One Piece to introduce crazy characters and that's why I love it, a freekin' mermaid and a star fish guy!

Going by the preview, the new bad guy is masked and apparently wants revenge on the Straw Hats aaaaand this is supposed to be where the Shark people come from? Would be pretty sweet if Arlong makes a comeback.

Oh I don't read the manga but thank you RyougaZell for posting about that, always interested in the differences between this and the manga.
