#2 Bray Wyatt

Bray Wyatt may have never won a title in NXT, but he more than made up for that with his polarizing personality and similarity to that of Charles Manson. He was an absolutely gifted speaker that could talk in a way that was both poetic and scary at the exact same time. He also had the size and agility to be one of the company's top stars.
To be fair, WWE did start Bray Wyatt and his Wyatt family off promising enough, but it always seemed to be bogged down by something. In fact, he either lost a crucial match, lost family members or was made to look like a fool by someone more powerful than him. In all honesty, it was brutal to watch at times.

Take for example WrestleMania 30, where despite many fans thinking that Wyatt would finally be put over by John Cena, it didn't turn out that way. In fact, Wyatt took a huge loss at WrestleMania 30 to The Cenation Leader and only got his heat back after defeating Cena in a very strange cage match the next month.
Fast forward to now and Wyatt is having much of the same problem he had before. Of course, he has added problems, like his missing child payments and getting into a car accident, but Wyatt still deserved better than that. Unfortunately for Wyatt and Woken Matt Hardy, however, The Woken Warriors lost the titles to The B Team after a two-month reign.
If nothing else, that is the epitome of Bray Wyatt's time in WWE. Someone WWE tries to do something with, but then loses faith in it and buries it completely. They did it with The Wyatt Family, they did it with Wyatt's short WWE title run and they continue to do it every single time that the man even builds up an inch of momentum.
In all honesty, what WWE is doing to Wyatt is hard to watch. Of course this all probably wouldn't be happening if WWE would have had Wyatt retain The WWE Title at WrestleMania 33, but they decided to move him to Raw instead in the superstar shakeup and haven't done very much with him since!
