#1 Bray Wyatt

We have been here many times before. Bray Wyatt has been missing from WWE programming since the summer. He has made a couple of house show appearances, most notably at Starrcade when he faced and defeated Baron Corbin. But it has largely been a mystery. Wyatt has said on social media that he is close to returning and that it would be something huge. It'd better be huge after WWE has kept us waiting for so long.
The perfect time to have the return of Wyatt would be on the post-WrestleMania episode of either Raw or SmackDown, or possibly even the Superstar Shakeup. After many stop-start pushes with the Eater of Worlds, this next chapter in his story is extremely crucial. Hopefully, it is worth the wait and WWE do indeed push Bray Wyatt as far as he can go. Feuds with people like Drew McIntyre, Kevin Owens, Daniel Bryan and others do seem tasty.
Who knows, maybe WWE will go all the way and give Bray Wyatt the WWE Championship that he once held for a very short period of time. They don't know what they have in this guy. Whether it is in this character or a different one, Wyatt will nail whatever he portrays on WWE TV when he returns. Run.
