#4. Nikki ASH is WWE's newest superhero and every superhero needs a supervillain like The Fiend Bray Wyatt
Nikki Cross' new 'Nikki ASH' character is a positive, bubbly, high-energy superhero character who's just trying to make the world a better place. This makes her the antithesis to The Fiend Bray Wyatt who is a demonic monster who wants to hurt people.
Every superhero needs a supervillain and The Fiend Bray Wyatt is the closest thing that WWE has to a supervillain. This makes the two conceptual sworn enemies and essentially means that the feud between the two would write itself.
Sure, we have the same issues we have with Alexa Bliss regarding WWE's reluctance to do intergender matches. But just imagine a cinematic match between superhero Nikki and evil Fiend. That would be amazing.
Plus, you have the added storyline elements of The Fiend taking Nikki Cross' best friend Alexa Bliss away from her and corrupting her into who she is now. So Cross could be out to, ahem, avenge, her lost friend.
