Rey Mysterio wasn’t always “Rey Mysterio.” The first time WWE’s Little Big Man made that uneasy climb to the top rope as a teenager in Mexico, he was “Colibrí” — the hummingbird. It was the perfect name for the man who would one day fly through the air with such weightlessness, such blatant disregard for gravity. Soon, he would become Rey Mysterio, but he would never lose that effortlessness in flight that made his so captivating to watch. Rey — like any great athlete — was capable of things that normal men thought impossible. While the rest of us were firmly planted here on earth, Mysterio was reaching unimaginable heights.
