#1: "The Fiend" Bray Wyatt attacks Roman Reigns

Bray Wyatt and Roman Reigns have faced each other several times in WWE, and that is a fact.
Ever since Bray Wyatt re-packaged himself as The Fiend, it's almost as if both Reigns and Wyatt have been purposefully kept apart from each other.
The ramifications of such a huge matchup may have stayed with us for a long time, so it makes sense why WWE didn't want to execute this idea right away.
But that doesn't mean The Fiend and The Big Dog's paths won't cross anytime soon. Both of them are on WWE SmackDown, and whenever Reigns decides to come back, The Fiend will always be lurking in the shadows.
Even if Bray Wyatt doesn't go after Reigns, both of them will inevitably clash if Wyatt becomes the Universal Champion in the near future. Roman Reigns has a strong motive to challenge for that title, and it doesn't matter whom he may have to face in order to become the new Universal Champion.
Either way, this new incarnation of Bray Wyatt doesn't forget, so it's likely that he may come after the one WWE Superstar who has dominated the "old" Bray Wyatt for years.
