#9 'The Demon King' Finn Balor
Finn Balor's versatility as a performer can be easily seen through his terrific characterization, with one embracing the light, and the other glorifying the dark.
While Finn Balor 'The Man' has been terribly booked on Monday Night Raw, it is the Demon King that garners tremendous reception for the First-Ever Universal Champion.
The 37-year old has created a demon of his own that understands his dark side and complements his artistic yet offensive wrestling ability.
He has often acknowledged that he extracts his source of energy from a Demon that descends his inner fears and catapults him into a different stratosphere of the dark.
Since his debut on the main roster, Vince McMahon initially picked Finn Balor's alter-ego as the one to defeat all odds, and become the next big-thing. However, his injury constraints sidelined him and unfortunately, his credibility under Vince McMahon too.
Considering that he has never lost on the main roster representing his alter-ego, there's no denying that the Demon King is perhaps one of the most compelling characters in WWE today.
If provided with some careful booking, this could certainly ascend Finn Balor to the top of the WWE, again.
