#4 Bray Wyatt

If you thought WWE's resident spook artist had run out of ideas after years of pulling off the same cryptic shtick, you had another thing coming.
Enter Sister Abigail.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
Yes, her introduction on Raw was underwhelming. But it seemed like the WWE decided against introducing her as a separate character and instead just made her out to be a dark and sinister part of Bray Wyatt...not unlike the Demon's association to Finn Balor.
However, Abigail revealing herself to the WWE Universe (despite looking remarkably like Bray underneath a veil of fuzzy distortions) may be exactly the kind of boost in momentum the Eater of Worlds needed at the moment.
And perhaps it's even enough of a push to justify a sustained run with an important Title. After so many years of being undercut at the big stage, I can't think of any other Superstar who deserve it more.
