While Mamono certainly seem to have similar standards of beauty as humans do, it's also much less important to them. What they care more about than appearance is if the man in question is (even deep down) a decent, loving person who can return their affections, impregnate them, and give them plenty of Mana.

So, in short, if a Kryptonian or Saiyan has those traits (and I'm not sure if they would have mana or similar), then yes, a Mamono could be attracted to him.
