Man, Bonney's my favorite from the get-go I think, hope she doesn't just fizzle out and loses without showing anything, like Roshio The Executioner did, not that I cared anyway about him.
I'm against Apoo havn't eaten a Devil Fruit, same for Bonney and Capone. I actually hope most of them havn't eaten Devil Fruits, like Kid.
Bonney doesn't seem to me like she'd have a devil fruit. If she did, with her nickname "Big Eater" that brings to mind Baku Baku no Mi, what Wapol ate. And about her being thin, that brings to mind Sube Sube which Alvida ate. Capone, I'd like to see him do something, but I can't actually picture it. I can't see him being extremely fast, or extremely strong. I can see him as more of a guy like Krieg but more refined. Weapons, Numbers, and strategies.
Apoo seems confident in his abilities, Martial Artist, probably a good Tactician, can see him and Sanji going at it.
Law seems like he's gonna end up being pretty big soon/later on, just from the impression he gives off, and being one of the last introduced, how he spoke to Drake, just the feeling I get from him. Drake seems like he'll be doing something important eventually, he seems more mature, being a Ex-Navy and stopping Killer and Urouge from going at it.
