Smog is a round-faced man with black hair, thick eyebrows, and narrow eyes. He has a big, flat nose, and, due to working with poisons, he commonly wears a mask over his face to protect himself from the poisons.
Poison Making/Chemistry: Smog is an expert poison-maker who is able to concoct his own unique and deadly poisons, viruses, and more. The ability also extends to medicine as he is able to make his own medication pills to combat the deadly virus (really a simple stomach bug virus).
