#4 The Demon King
In his first month on the main roster, Finn Balor beat Roman Reigns and Seth Rollins and also became the inaugural Universal Champion. He had a proverbial rocket strapped to his back but, a career-threatening injury derailed that push majorly.
Now since coming back, Balor has taken clean losses to Bray Wyatt, Roman Reigns and Kane.
But when he evolves into his alter-ego of the Demon King, he does not lose. Now, this would be a bout the WWE Universe would love to see. The undefeated Demon King versus Vince McMahon’s chosen one gives us a match that nobody on the planet could predict.
