Towering monsters, mutated beings that adapted to the harsh conditions in Chrome Shelled Regios. They roam freely and hunt for human cities as their primary food source.
Filth Monsters are giant mutated creatures that dwell on the inhospitable and hazardous lands of Chrome Shelled Regios. They are beings that can live outside the moving cities. Their body adapted to the corrosive nature of the Pollutants. Furthermore, they can consume Pollutants for food. Still, the nutrient value of the Pollutants are very low. As such the Filth Monsters are hunting for human cities for food. To them, a moving city is like a huge picnic basket.
