Drown myself in google links until I have a vague idea of what a character who exists within the setting would act, and how the environment shaped them as opposed to a more modern upbringing. Researching is key.
I can think of many uses for shape-shifters, just saying.
So, the implants determine what you can shapeshift into?

Just what can't you shapeshift into? xD
