#4 Aleister Black
Aleister Black was a global star long before ever stepping foot into a WWE ring. Known all throughout Europe as "Tommy End," he had established himself as a proven champion with over a decade of notable, professional experience to his credit.
When he arrived in NXT, the fans were immediately drawn to his undeniable in-ring superiority and his overall skill level which he demonstrated flawlessly from the very beginning.
While he's only been with NXT for roughly two years, Black has already proven that he has the goods to not only survive at the top but to excel and likely compete for a championship very quickly.
