Potential WrestleMania main eventer #5: Aleister Black

Real Name: Tom Budgen
Height and Weight: 6'0" 215 lbs.
Years in the Wrestling business: 17 (veteran.)
In ring style: Striking and technical wrestling.
Formerly known as Tommy End, the man now known as Aleister Black has been training in traditional martial arts and kickboxing since he was old enough to walk.
His combat sports training was a great boost to his pro wrestling career, giving him a spectacular move set right out of the box. However, Black is more than just another 'karate guy' striker. He has fleshed out his repertoire with a variety of more technical moves, and can trade submissions with the best of him.
Black was one of those independent scene superstars who no one ever thought would be signed with WWE, and yet here he is, about to be moved up to the main roster.
Why he might main event WrestleMania someday: Aleister Black has the total package in terms of look, skills, and charisma. WWE is obviously heavily invested in Black, perhaps even seeing him as a spiritual successor to the Undertaker.
