Zero. Definitively. Axl's is a decent fighter, but Zero's power and experience would overwhelm him. Axl would last a bit longer if the fight took place during 22XX (as opposed to 21XX), since Axl then had the ability become totally invisible for periods of time. Still, Axl's best power is in his ability to shapeshift into more powerful bodies, but unless he copies X or Sigma, it simply won't be enough to put down Zero's power and skill.
