“Here in the lower world, garbage accumulates quickly and along with it so do all kinds of emotions and thoughts.”
Trash Beasts (斑獣 Han-jū) are creatures that exists on the Ground. Their bodies are made of waste products and were given life via the power of Anima.
Overview[]
Anima (思念, Shinen) is a mysterious power source seemingly made of literal thought and emotion, which accumulates and turns into energy, serving as an Anima that causes various phenomena, Trash Beasts are formed from the trash thrown down from the Sphere. The collective thought imbued in their contents gives them life. Since they’re powered by Anima, they can only be defeated by an object with a Anima too such as a Vital Instrument.[1] This shows contrast between the two phenomena, as Vital Instruments, fueled by love and care, serve their human owners with the power they develop, while Trash Beasts, made from things carelessly discarded, lash out against humans.
Imitation Trash beasts[]
A different variant of Trash Beasts are those who possess cores and can’t be defeated unless their cores are destroyed,[2] they were created by Zodyl Typhon who experimented to create artificial Watchman Series items, his experiments ended in failure however but he discovered that the failed watchman series items could be used as a core and upon giving Vital Instruments to it as offerings it would evolve into an imitation trash beast.[3]
Appearance[]
Trash Beasts bodies are made up of trash, as the name implies. Also as the name implies, they assume the forms of beasts; this can entail abstractly monstrous forms, imitations of living animals, or, occasionally, something based on their components (the remains of an abandoned house form a house-themed Trash Beast with its eyes in place of windows and mouth in place of a door, for example.)
Habits and Behavior[]
Trash Beasts’ main habitats are the Polluted zones on the ground, since these areas contain the trash they're born from. They are seemingly animalistic, although this can be attributed to the undirected emotion imbued into them by the thoughts their components were exposed to. They lash out and attack most humans they come across (although likelihood of provocation and means of attack vary by Beast) and sometimes even break into towns,[4] making them a public hazard. Once killed, or "cleaned up" by a Vital Instrument, smaller pieces of debris tend to crumble and blow away shortly after death. Provocation of Trash Beasts varies by beast, but is generally rather easy to do. Examples of triggers for attacks include entering their territory, making them feel threatened, or loud noises, but some attack on sight.[5] The reason for this aggressive behavior, beyond animalistic instinct and the undirected negative thought imbued into them, is largely unknown. Perhaps it's spite or resentment from being discarded, perhaps something else... it's unknown, as the series primarily uses Trash Beasts as plot devices, fodder enemies to be fought and killed, and thus their hypothetical psyche is not explored.

Trivia[]
- Trash Beasts are known to only form in the Ground, this could possibly be due to thought (the power system, not the brain function,) not existing in sufficient concentrations elsewhere, as Rudo wasn’t able to use 3R’s abilities in the Sphere despite it being a vital instrument.
- The description of the scorpion Trash Beasts encountered in Penta as "dumb" implies that other Trash Beasts are at least intelligent enough to make the scorpions seem less intelligent by comparison.
