#1 Nikki Cross
There is literally nobody better suited for the part of Sister Abigail in WWE than Nikki Cross is. I mean you could always make the argument for Rosemary, but she's going to be a part of Impact Wrestling for a long time now, having already signed a major deal with the company.
The fact that we still don't know whether Nikki Cross will be a part of RAW or SmackDown Live certainly alludes to the fact that there could be special plans for WWE's twisted sister. In fact, the vignettes show a very creepy doll and that could pertain to Nikki Cross' WWE gimmick.
With Nikki Cross by his side, Bray Wyatt could certainly become an unstoppable force. Nikki Cross could make the character of Sister Abigail her own and leave the WWE Universe transfixed with her incredible mix of sports and entertainment skills.
