#3 Bray Wyatt himself
I admit that this will be an odd choice, but then again when has Bray Wyatt not been odd? If you remember his feud against Finn Balor, Wyatt teased a split personality where he would dress up as Sister Abigail and even speak at a much higher register.
We all know that the fun and games of the Funhouse are going to end soon, and there's no better way for that to happen than with a split personality storyline. I know that Abyss is a key figure backstage now and they've done this storyline before with Abyss and Joseph Park, back in TNA.
There's a big chance that the WWE Universe could potentially turn on Bray Wyatt if he does go ahead with this gimmick. Therefore, I wouldn't be the biggest fan of him doing this.
I would rather pick one of the following women for the role.
