When it comes to fics, do you reuses the same OC for different fandoms?

I was wondering: am I the only one that reuses the same OC? Like, it’s the same personality wise but the only thing that changes are the age or appearance but in spirit remains that same character? I have one OC in particular that is in each of my fics, I’ll name her Xiao Hua for now, she can vary in age, appearance, job ad even slightly different names but she’s always the same personality wise. Her wants, her needs, her weaknesses and her strengths don’t change, just how they are represented.

Does anyone else have an OC like that? One’s who’s versatile and fits the narrative of the story you’re telling regardless of what their place is? Be it blank x reader or a side/background character.

I’m curious to know.
