#4 Charlotte Flair
Similar to Roode, the genetically-superior gimmick of the current SmackDown Live Women's Champion works better as a heel.
Moving to SmackDown Live last year, Charlotte turned face, winning the title from then champion, Natalya. However, fans have been critical of the move, saying Flair has been made out to be this unbeatable force, similar criticisms for Roman Reigns.

Things haven't been helped by the fact that Flair very quickly regained the championship after returning before Summerslam, stealing the victory from genuine fan-favourite Becky Lynch.
WWE has since turned Lynch heel, and have tried to portray both women as having valid articles, but that booking doesn't hide the boos this face gets, every time she walks through the curtain.
