Mimic

4
You are walking one evening, and as the sky gets darker, you notice someone matching your every move. Youโve had some training/you have a weapon, so you turn into an alleyway, and turn to face โhimโ, but โheโ just stands there, same position and stance as you. You ask who โheโ is.
โheโ instead of he, because the appearance is that of a male human, yet it is just that. The appearance. Mimic does not have a real gender. It is the only one of its kind, because it cannot reproduce.
It copies every single thing you do and say, like a mirror image
It has beady pitch-black eyes outlined in red, as if it had been crying for hours, unruly dark hair, and always wears the same clothes, especially its long brown trench coat. It doesnโt know how to brush its teeth or shower, so its scent is quite thick, along with the dirt and grime on its skin.
