#4 Gangrel vs The Fiend
Remember when WWE brought back The Boogeyman at the 2015 Royal Rumble where he quickly got eliminated by Bray Wyatt? There's another sinister entity that could have a one-off match with Bray Wyatt's alter-ego, The Fiend. Gangrel was possibly the creepiest WWE Superstar of the Attitude Era. He used to spit blood before his matches, a move that suited his gothic, vampiric character very well.
Bringing back Gangrel for a quick bout against The Fiend doesn't seem a bad idea at all, considering the fact that the former is still active around 20 years after the Attitude Era's demise. He recently participated in a battle royal for ROH Free Enterprise. The Fiend is one of the scariest characters in WWE's storied history and what better way to cement him further than to have him squash one of the creepiest Superstars to ever have stepped foot in the ring?
Similar to how Wyatt made quick work of The Boogeyman a few years ago, The Fiend could put down Gangrel in a matter of seconds in a TV match, solidifying his character further.
