#5 Demon King enters and wins the Royal Rumble

This is the one possibility that enthrals me the most. There is no doubt in the fact that WWE fans long to see the Demon King perform. His Demon King persona takes Finn Balor to the next level and adds even more energy to his already energetic personality.
Ever since Finn Balor won the Fatal Four Way match at RAW for the right to challenge Brock Lesnar, there have been questions about whether Finn will show up at Royal Rumble as the Demon King or not. Though, Finn recently spoke in an interview about it and put an end to all such speculations by saying that he will face Brock Lesnar as Finn Balor, the man and not the Demon King as he has relied too much on the Demon in the past.
But, this does not mean that he cannot wear the paint at WWE Royal Rumble. It is possible that Finn might lose the championship match due to outside interference, probably by Braun Strowman or even Paul Heyman, but then enter the 30 men Royal Rumble match. I already wrote a fantasy booking article about it. One thing is for sure. If Finn is going to enter the Royal Rumble match as the Demon, he will end up winning it. Imagine what it will be like if Seth Rollins and Drew McIntyre are the two remaining superstars out of the first 29 entrants with the Demon entering at No. 30. The expressions on their faces and the reaction of the WWE Universe will say it all. Demon King winning the Royal Rumble to close the show will be an awe-inspiring moment.
