With its fierce heat, gaseous attacks, and immense destructive power, a rampaging Coalossal is seen by many as a metaphor for the industrial revolution. Yet premodern cities (if more rarely) could also be lost to their smog, and actual factories and pollution have caused many disasters for which these pokemon are unfairly blamed. Coalossal have often been compared to moving volcanic eruptions, although it takes a rare Gigantamax and terrible luck to cover an entire city in coal and ash. These pokemon are walking natural disasters, and simply approaching one close enough to breathe its fumes can be fatal. The scorched earth covered in hot tar left behind after a Coalossal walks by can blight prosperous farms or whole city blocks; at best, once the heat settles down, it can be mined or recycled as a fuel source.
Although running away is always the right move when faced with a rampaging Coalossal, human beings often have things they wish to protect, or are prevented by terrain from leaving. Some brave trainers have made it close enough to trap them in a pokeball; far more have perished in the process, or bought only a few seconds before fleeing, or, most commonly, simply missed the target. Sufficiently strong water attacks can fell them, but most water pokemon to attempt such only serve to accelerate their destruction, transforming slow turtles weighed down by their own coal into natural steam engines in the process. The most reliable way to stop a Coalossal is to return it to the ground from where it came.
Modern pokemon arenas must contend with a variety of dangerous pokemon, and battles in which Coalossal participate see masked trainers, while crowds watch behind reinforced glass; with these precautions, they have competed safely (if not often effectively) in the Galar League.
