Agreed, with both Goth and JS. It is possible unicorns existed at some point or another, considering all current living organisms are just 1% of all organisms that have ever lived on Earth. And JS, several mythological creatures do surpass unicorns. My original comment was intended to be kind of a joke and it spiraled out of control, which I enjoyed.

I'd say one of the greatest mythological creatures is the phoenix. Specifically, the phoenix Fawkes.
