#4 No blue tongue/pink hair
The professional wrestling industry is booming at the moment, and the need for every Superstar to stand out from the multitude of talents in the WWE roster is immense indeed. Liv Morgan had a unique thing going with her look. Her pink hair, as well as her blue tongue, ensured that she had a distinct identity on RAW.
But because she says that she needs to be real, maybe what is going to happen is that she will drop this look and get set for a complete reboot, in a sense. This would not be unlike Carmella going in for a different look when she went babyface and allied herself with R-Truth.

I'm guessing that this could certainly be the case because a blue tongue is arguably the least 'real' thing about Liv Morgan's gimmick. If she comes back in a new persona, fans would certainly dig it.
