Predictably, Pyro goes around setting fire to everything. His BAM adds Crisis tokens to both adjacent Locations, and if a Hero ends their turn in such a Location, they automatically take damage. Heroes can play firefighters by using Heroic actions to put out the flames. Of course, this is made a lot harder if the Location has one of Pyro’s Flammable Materials Threats, which double the number of Crisis tokens placed there.
