I was wondering if some of the Shichibukai are as powerful as everyone thinks. It seems that there bounties seem kinda of low for there power. I mean Crocodile was only 80 million and even if he wasn't captured, it would have been 160 million. But compared to the other know bounties, 340 million, 296 million, and 320 million, Crocodile seems pathetic. Luffy could probably become one of them if he were to ask, he's bounty is 300 million as well as Zoro. So either the bounties are too low or they were raised to a point where no one had seen such a huge amount and they were asked to become the Shichibukai, with the exception of Crocodile. (evidenced by the fact they all had former bounties but that could just mean they are no longer in effect or something)
