#2 Feud with Demon King Finn Balor
The Fiend's first opponent in WWE was none other than Finn Balor and while the contest turned out to be nothing more than a glorified squash match, it could have planted a seed for something later. In fact, it could be one of the greatest dream matches of all time and might even help reestablish Balor as The Demon King.
If nothing else, WWE really needs to follow up on the events of SummerSlam in some capacity. Not only is that evident by the way that battling The Fiend has seemingly revived Balor's career, but also by the supernatural element WWE could incorporate into the match.

In the end, Demon King versus The Fiend is a great way to go back to where it began, help flesh out Balor's supernatural character and give The WWE Universe a dream match to rememeber.
