Portgas D. Ace
Rayleigh hurt Kizaru without getting hurt himself. He's got the speed to counter speed-of-light attacks. Sorry, Ace, but you can't win this...
I'd say we only saw a little of Ace, his potential is definitely greater than that of Dark King Rayleigh. Sad to say, he died before he could reach his greatest form. Even aged Rayleigh can be bothersome for Ace, if not too much. From watching a glimpse of Rayleigh vs Kizaru. I'd say Rayleigh wins, though he has aged, he's still deadly. If someone can show that Ace could use a high level of CoA, I'd say he wins, but that is not the case.
Ace starts to cry with just the idea of fighting Rayleigh. Let's pass this versus quickly please.
There is not even something to discuss in my eyes. Rayleigh stomps.
Rayleigh wins. The End!
rayleigh's haki allowed him to fight and be in advantage against kizaru,whose rogia should be stronger than ace's (although oda humiliated it,by slowing it down too much!). btw,rayleigh owns ace,that's sure.
Ray is the winner . The experience is also important . Ace is still too young for this experienced fighter
Not enough on Ace except the fact that he tied with Jinbei and was punked by Blackbeard. Rayleigh should win.
Poll is up.
So yeah I agree with everyone here, clearly Rayleigh has the upper hand here, he knows way too much about haki and the world, and basically everything that Ace would not be a problem for him to beat. It comes down to experience, but not any kind of experience, FIRST MATE OF THE PIRATE KING LIKE EXPERIENCE.
Really.... nothing to say. We know Rayleigh is the man
The only thing we saw from Ace was a string of losses, unfortunately. He never quite lived up to expectations. Rayleigh, however, has shown his ability against Kizaru. Rayleigh wins.
