#4 EC3
EC3 may have returned to the WWE now, but for a long time, he was seen as one of the biggest wastes of talent in modern WWE history.
Back in the days when NXT was one of the worst things on the WWE schedule, EC3 was a contestant on the show under the name of Derek Bateman. Bateman was partnered with Daniel Bryan on the show before making a forgettable debut on the main roster.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
The former Impact World Champion's time in the company was a massive failure, and he would leave in 2013 at the end of his contract. He would then go on to join TNA/Impact, where he rose to the top of the roster playing the entitled nephew of Dixie Carter, Ethan Carter III.
Carter quickly became one of the brand's biggest stars and after five years with the company, was eventually resigned by the WWE in 2018, making his debut on NXT at NXT Takeover: New Orleans, one night before WrestleMania 34.
