#3. Finn Balor
It's officially time to say goodbye to the permanently smiling Finn Balor and say hello to a heel who struggles to silence the emergence of a demon threatening to annihilate the entire WWE locker room.
WWE has yet to capitalize on the potential of the Finn Balor/Demon duality, choosing to have Balor don face paint randomly, without explanation, as opposed to exploring a backstory which could create a modern-day Dr. Jekyll and Mr. Hyde story in a pro wrestling capacity.
With Balor currently holding the Intercontinental Title, now would be a great time for the Balor Club leader to turn heel and unleash the Demon on both the WWE Universe and ultimately, himself.
It's not lost on me that WWE might be heading down a similar path with Bray Wyatt's new direction and his Fiend character, but Wyatt's character has always been portrayed as mostly "insane." The Finn Balor and Demon duality present WWE the possibility to create a simultaneous babyface and heel dynamic, which could do wonders for both Smackdown Live and Balor's current direction.
