Rayleigh (post time-skip) vs Marco

[SSJ2]

Who wins?

 

[Captain Cadaver]

Rayleigh, most likely. Unlike the other Legends, he probably hasn't weakened at all when considering he lives a far more healthy lifestyle and was actively training Luffy in the ways of Haki for several months, as opposed to Sengoku and Garp not really being suggested to be in positions where they could get much exercise.

Do you think he has the stamina to win? Marco more or less has infinite health/stamina, and can hold his own against Kizaru. Given that Rayleigh has commented on his old body not working the way it used to, I'm not sure that he'd be able to finish off Marco before his body gives out.

 

[Captain Cadaver]

Marco definitely has an edge in stamina, but Rayleigh should be far more experienced especially when it comes to Busoshoku Haki. I can see him using his skills to negate Marco's DF abilities and take him down in time, albeit with extreme-diff.
