@Monquito:
Kizaru can't beat the firs commander of a yonkou but Rebecca can do it easily because potatoes???
Treating Burgess as if he is Marco equal, just because they have the same title, doesn't make much sense! Given that it was two different people and "institutions" that gave them the positions.
- Kizaru, an Admiral, couldn't beat the first commander of a Younkou but Garp a vice admiral could.
- Kizaru fought normally against Marco, but put his hands in the air when Beckham, Shanks first mate, threaten him.
We don't really know anything about Burgess overall power and the reason why Blackbeard give him the title of first commander, and if Blackbeard even knows how to give titles(Certainly he didn't knew how to grade his enemies: Magellan and Whitebeard defeat).
We only know that Burgess his physically strong and that last time we saw him fight, he couldn't handle Ace.
More, we know that fights in One Piece aren't only power-levels where you give a number of power to the characters and compare them and you have your result, but is more complex.
I'm not even saying that she will win against Burgess, but that of all the other contenders he seems right now the most probable for her to win, if she ever wins against anybody.
We have:
Barto - Defensive barriers, he basically doesn't move nor attack his enemies. Rebecca normally try to finds her enemies openings and use it, but Barto show openings just to use his abilities and counter his opponents.
Sabo - We don't know nothing about Sabo, so guessing the compatibility of him against her is impossible.
Diamante - We don't know nothing about him either, except that he is one of the long leg tribe, just like Tamago. Impossible to guess too.
Burguess - Wrestler that uses his strength to take his enemies to submission, as seen in Jaya, Against Ace and in the first block where everybody was beaten to a pulp(unless he made a weird special attack that we don't know, it was brute force). He is a very offensive person and we don't have any indication that he is fast. So we can take that he will try to attack her and keep trying(wasn't he shown to be simple minded and straight forward person? At least at Jaya and against Ace it was the impression that he gave me) and that she will be able to normally dodge every of his attacks. As I said in the other post, if they fight it be in suspension if he can land a hit or if she can find a good opening. Don't forget that in this tournament you just need to throw the opponent out of the ring.
