#4 The Fiend must be scarred or burned to a certain degree upon his WWE return
The Fiend is a supernatural monster, but even this character had to take some time off after being set on fire at WWE TLC 2020. So in terms of the storyline, Bray Wyatt's alter ego isn't invincible after all.
It can be assumed that while the fire couldn't kill The Fiend, he was affected by it to a certain extent. This result would explain the character's absence from WWE programming. Perhaps The Fiend is recuperating from the injuries he suffered at TLC.
The events of Randy Orton and The Fiend's Firefly Inferno match shouldn't be forgotten anytime soon. Upon the return of Wyatt's alter ego, the character should display the scars he suffered at TLC.
This won't be the first WWE will lean on the makeup department for this particular saga. In January 2021, Orton wore a protective face mask with heavy makeup to sell his burns after Alexa Bliss launched a fireball toward his face. But this development didn't last long, as it was entirely scrapped after the Royal Rumble pay-per-view.
Let's hope that if WWE decides to implement some kayfabe scars or burns over Wyatt's body, the company should at least stick with the effects for a while.
