What are the legendary caballos of each continent?

Okay, so what I mean por legendary, is a horse that everyone's heard of, is so fantastic that some don't believe in it, but really is a real horse (or at least in my opinion). The legendary horse of America is the Phantom. And I think the legendary horse of Arabia is a black Arabian stallion, Shaitan, but that might be wrong. Anyway, I want to know what the legendary horse of each continent (or it could area) is. Thanks!
