OC in different universes?

Does anyone have an OC that is in two different universes? What are the similarities and differences between your character in both universes?

I have an OC that is based in the Monster High universe. Appearance wise she has the same aesthetic as other characters in Monster High. Her power is that she can control the elements. I thought it would be fun to create her in Word of Warcraft as a shaman because they control the elements. It would be fun to actually play her experiencing her powers. The problem I’m facing is my OC can’t have her usual aesthetic in WoW because they don’t have customization options that would make her look like the version I created. What would you do in this situation? How would I make it make sense in roleplay that she looks so different in both universes? Does anyone have any ideas on how I can make this character seem more like one character instead of two very similar characters?
