#2. Former WWE Superstar Aleister Black (Malakai Black)
Former WWE Superstar Aleister Black has just debuted as a surprise for All Elite Wrestling, appearing in the ring after a blackout to hit the Black Mass on Arn Anderson and Cody Rhodes. He looked like more of a star in that small segment for AEW than he has for his entire main roster run in WWE.
That wasn't always the case for Aleister Black. In NXT he was one of the best wrestlers around, he went on an extended undefeated streak, became NXT Champion and looked unstoppable. He was also presented as this brooding, slightly mystical character with an amazing entrance and a great theme song.
However, all of those things that made Black unique outside of the ring slowly started getting stripped away and all he was really left with was his in-ring work. Sadly, despite all his talent, Black wasn't able to string together enough momentum to really make an impact on the main roster.
WWE ended up releasing Black earlier this year and thanks to a mistake in his contract he was able to jump ship to AEW. Now as Malakai Black, he'll hopefully hit the heights fans were expecting him to during his time with WWE.
