#1. Could Karrion Kross and The Fiend Bray Wyatt clash over the dark arts
The Fiend Bray Wyatt and Aleister Black were the two real supernatural characters in WWE after Finn Balor stopped transforming into The Demon. However, Black has now left WWE and joined AEW.
But WWE now has Karrion Kross who has very quickly become NXT Champion and looks to be hot-shot towards the main roster sooner rather than later. Kross' character is, by his own words, a blend of realism and supernatural.
Kross' whole presentation is certainly leaning very much into the supernatural with his entrance, the hour-glass motif and his valet Scarlett who certainly has a mystical quality towards her.
So naturally, The Fiend Bray Wyatt and Karrion Kross would be a ready-made feud given they both have characters grounded in supernatural elements. Just imagine the scenes, Karrion Kross finally makes his main roster debut and then The Fiend returns to stake his claim as WWE's only supernatural guy.
