Friday Night Funkin' Dark Impostor Sticker
This character with micro is from FNF VS. Impostor mod that features characters from the popular sci-fi mystery murder Among Us game. As you understood, the antagonists of this mod are Impostors, which are the main antagonists of Among Us. This Impostor, probably, lost the game and became dark-colored. And now he is just a fanart Friday Night Funkin' Dark Impostor Sticker.
