#3: An intriguing contrast for Wyatt, a WWE character born out of hatred
Although Wyatt has turned babyface in WWE during his run as 'The Eater of Worlds', the situation is quite different when it comes to The Fiend.
It has been frequently established that The Fiend was created as a result of all the suffering that Wyatt had to endure for years. The Eater of Worlds couldn't eventually handle the pain, so when that character ran it's course, an even stronger personality was created as a result.
So for a character that is supposed to represent all things that are evil, a babyface turn for The Fiend would be a stark contrast, in general.
Fictional shows like Mr Robot have artistically depicted Dissociative Identity Disorder in the best way possible. Though while this writer is aware that there is a huge difference in the quality of writing between SmackDown and Mr Robot, Wyatt is the kind of creative genius who can be trusted to transcend the limit of fictional storytelling in WWE.
As discussed above, The Fiend exists for a reason, and for the character to transform into a babyface would be a contradiction as to the nature of its very existence. For this reason, a babyface run for 'The Fiend' Bray Wyatt could be the ultimate character change in WWE history.
