The Bulletproof Balor Club:
This would be INSANE!!! The history between Finn Balor (former NXT Heavyweight Champion), Karl Anderson and Luke Gallows is known to every pro wrestling fan across the globe.
The founding member and leader of The Bullet Club in New Japan Finn Balor (aka Prince Devitt) can take the throne, reunite with Anderson/Gallows and makes his intentions clear that he wants the biggest prize in the world of pro wrestling, i.e., The WWE World Heavyweight Championship and NOBODY can stop the Demon within.
Here, Anderson/Gallows rush to the ring in the closing moments of the main event, and put BOTH of the competitors out of their misery and then they welcome their leader in the name of Finn Balor. Hence, the Bulletproof Balor Club stands tall and Finn poses with the WWE World Title belt as the screen goes to black.
WE ARE BULLETPROOF, WE DO WHAT WE WANT!
