#1 Nikki Cross
Getting a new female character could be something WWE could be planning for the Firefly Fun House, considering Bray Wyatt teased to introduce Sister Abigail two years ago, but it never happened. When Bray Wyatt debuted his new character in Firefly Fun House, a preponderance of fans had speculated that Sister Abigail could finally make her TV debut. Given The Fiend has been enjoying a fruitful run, it may be the perfect time to bring in the Sister Abigail character.
The question remains who could portray a mystifying character like Sister Abigail. Nikki Cross, who had a lunatic gimmick in Sanity, could be an ideal choice to play a new character in Firefly Fun House. Sanity was a popular stable in NXT and Nikki Cross became a crowd puller with her character. Although Cross continued her previous gimmick in the early part of her main roster career, she eventually renounced it, associating with Alexa Bliss.
Bliss hasn't been around since losing the Women's Tag Team Titles, and Cross has been a singles performer for a while. Earning a title shot for the SmackDown Women's Championship a few weeks ago, Cross failed to capitalize on it. A debut in the Firefly Fun House could allow Cross to bring back her old self, and she could get the opportunity of reaching the top of the ladder in the women's division.
