Personality Shifter

personality shifter:

A personality shifter is a headmate that shifts personalities to mirror the person they are talking to. This may be for many reasons;

- Past or current trauma that needed the system to do this for their survival

- The body is neurodivergent and they need this role to mask as neurotypical

- For any other reason I didn't mention

This headmate may also be a shapeshifter, or take on the appearance of a snake. (This role is similar to personality shifting.)
