#7 Finn Balor - Curse
Fresh off his run with the Bullet Club, Finn Balor came to NXT with a lot of momentum and his Demon persona added mystery and artistry to the character. Every Pay Per View fan would gasp at his latest paint job, and he would move a hundred miles per hour in the ring.
His battle against Kevin Owens at the Beast in the East PPV felt like something outside of the WWE and told a great story.
Since making the move to the main roster we haven't really seen him get a lot of love. The fans love him, but his only real push happened when he first moved up and became the first Universal Title Champion, but he has stayed out of that picture for a while (Blame his Injury, but they could have brought him back with momentum).
They teased him reuniting with the Club recently, but it came across as less authentic than their run with AJ Styles on Smackdown as Balor kept being such a baby face.
Finn Balor represents potential, but WWE doesn't get how to use him properly. Maybe when they finally move him to 205 Live and loosen the control on him we might see something better.
