While the character of Bray Wyatt officially debuted in Florida Championship Wrestling - WWE's developmental territory at the time - it was part of the early days of NXT that things really began to take off (interestingly, Wyatt was also a contestant during the second TV season of NXT back when it was a reality/wrestling hybrid).
An unfortunate injury during the early days of this run actually brought about one of the defining elements of the character. A torn pectoral muscle left Wyatt unable to compete in the ring, but with big plans for him in the works, NXT needed to keep him visible. Enter The Wyatt Family, a team of brutes consisting of Luke Harper and Eric Rowan, who followed Wyatt's commands as he sat at ringside, creepily, in a rocking chair.
At one point after making their way to the main roster, Wyatt "freed" both Rowan and Harper, as WWE had intended on making them stars of their own. In fact, Harper won the WWE Intercontinental Championship on a couple of occasions, while Rowan went on a face run that, through no fault of his own, didn't end up quite as well as the company had hoped.
On the other hand, other former members have fared better. Daniel Bryan was a part of the Wyatt Family for a (very) short while, and his brief stint and breaking away from Wyatt's sinister grasp was instrumental in his historic run to the main event of WrestleMania XXX. Braun Strowman debuted as a member of the Wyatt Family, and has gone on to become one of the bigger stars of the company.
And Randy Orton, well... he's Randy Orton. He doesn't count.
But what about Bray's own personal achievements? After all, we're not just talking about a manager here. What has the Eater of Worlds accomplished on his own?
