#1 The Fiend and Randy Orton join forces and form an unholy alliance
After Randy Orton set The Fiend on fire, the biggest twist possible would be if the two of them join up and form an unholy alliance. We don't know how Bray Wyatt thinks. But there still may be a chance that he respects the lengths that The Viper went to just so he could come out on top.
Orton himself stated that he enjoyed burning The Fiend to a crisp, which is right up the monster's sadistic alley. Wyatt could realize that he would rather fight with this madman than opposite him, thus reuniting part of The Wyatt Family. Randy Orton is twisted enough to embrace the offer.
Is this man the funniest man in wrestling?
This could be birthed through several different channels. Orton could become part of Bray Wyatt's world after losing a Firefly Fun House Match between the pair. Since John Cena is a part-timer, the story of his fallout has not been told. WWE could upgrade the Firefly Fun House fallout by telling Randy Orton's story.
An alternative way for this alliance to happen would be through Edge. He could return during the blowoff match between Orton and The Fiend, before facing The Viper at WrestleMania. However, at The Show of Shows, The Fiend could cost Edge the match for interfering in his business.
As a result, Randy Orton joins the Firefly Fun House and Edge goes after Bray Wyatt. Meanwhile, Alexa Bliss could conquer the world and become the RAW Women's Champion. The storyline possibilities are endless with The Fiend and an updated version of The Wyatt Family.
