I'm quite liking the idea of having a stylized logo/emblem of your former body's species on the left of your chest and your designated number below it. That's something quite intriguing about seeing the little lingering hint of the rubber drone's past self.
When I returned to my country's airport, I discovered that someone tried to steal things in my luggage only to find my latex suit, leather gear, and dirty clothes.
Security scanned them and asked what those were for, I told them it was my swimsuit & mountain climbing gear.
I like the idea of Esgar stealing someone's appearance into a rubber 'skin' and then turn them into another Esgar/blank pelt beast and screw around with their mind.
Not sure what it is called... Identity play? Body thief/swap?
