It definitely doesn't now, but I'm fairly sure it will. Blackbeard doesn't want to become a Shichibukai for nothing. He wants to become Pirate King. The way Oda set the situation up -- Shanks barely being a match to Blackbeard before he lost his arm, and before Blackbeard got his fruit; Whitebeard being sick; Ace (who is supposedly stronger than Luffy) losing -- all indicates that Blackbeard is a contender for the PK.Originally Posted by Munsu
In short, none of the current super strong guys are a match for Blackbeard, which probably means Luffy will have to fight him to be PK.
On the other hand, Dragon is supposed to be a huge bad ass, and we know very little about him. And he's probably Ace's dad too.
