Markus is a model RK200 android who appears as a light-skinned man of color, with very short brown hair and light stubble. He has heterochromia, with a blue right eye and a green left eye. Since he is a deviant, he no longer has his LED. He is a strong leader, but the responsibility of being one leaves a great burden on him. He is wracked by grief, and harbors a deep hatred towards humans for the virus that corrupted his kind. His infected companion, Simon, is a model PL600 android.
