Appearance

Smog has a rounded face set with narrow eyes, heavy brows, and dark hair. A broad, flattened nose sits at its center, and because his trade involves toxins he usually keeps a mask on to guard against his own creations.

Personality

A meticulous streak defines him. He insists on brewing every poison and pathogen personally in a purpose-built lab rather than trusting anyone else's work. Beneath the profession sits a surprisingly humane man who tends to the people he infects when a job does not call for their death, and he refuses to unleash a genuine virus on the students once he realizes Takaoka never intended to hand over the cure.

Abilities

Smog's craft is chemistry turned toward harm. He formulates his own distinctive poisons, viruses, and related agents, and the same expertise runs in reverse, letting him compound medicine, including the pills used to counter what turns out to be nothing worse than a common stomach bug.
