Actually, the only thing I regret about the characters in this arc, is that we see hundreds of prisoners, yet the only ones who seem to have any devil fruit ability (or any real fighting power, for that matter), are the prisoners we've known since before this arc, and then the new major characters. But technically, ANY prisoner from say, level 4, should be stronger than Bon Clay, Buggy, and Mr. 3.

However, I love seeing people wig out when Luffy effortlessly defeats an overhyped character.
