All to remind you that no two Abnormalities should be treated the same. Cast of Snowflakes: Each Abnormality has a very distinctive design to help separate them from one another, sometimes even having different art styles, with their own list of needs, dislikes, skill checks, and fighting styles.Blue Star seems to have the legs of those absorbed into it protruding from its actual body the blue heart.Mountain of Smiling Bodies is a mountainous ball of decayed black flesh, bones and teeth, which only grows bigger as it eats more corpses.Once it transforms, it opts to mash all those parts into a hulking red humanoid mass of flesh and teeth. Nothing There is a barely-held-together patchwork of human body parts in the shape of a tripedal beast.Body of Bodies: A recurring theme among some Abnormalities.Big Bird aside, many Abnormalities display this behavior to your detriment, namely Fragment of the Universe, Queen of Hatred and even WhiteNight.

Blue-and-Orange Morality: As shown in Big Bird's lore, some Abnormalities have the intent to kill when they attack, but simply don't grasp the concept of death and may be attacking for varying reasons, some even being well-meaning but unaware of how to express it in any other way.Some Abnormalities like the Scorched Girl and Fragment of the Universe look like they're walking drawings with visible pencil scribbles, others remain faithful to the game's flat chibi art style like the Queen of Hatred and Laetitia, and then others like Schadenfreude are designed with photorealistic eyes and textures. Art-Style Dissonance: Happens semi-frequently and intentionally thanks to the Perception Filter installed on the Manager's camera and how well it works on a case by case basis.'D' presumably stands for Donator, which are Abnormality concepts pitched by the backers who helped fund the game. 'F' stands for Fairy-Tale, which are used on creatures based on real world fairy-tales. 'T' stands for Trauma, typically used on Abnormalities that are based on humanity's fears and strong personal experiences/emotions. To elaborate, 'O' stands for Original, based on no theme in particular. All There in the Manual: What the letters and numbers in an Abnormality's serial code isn't explained in-game, and is instead touched on through outside sources and especially the artbook.
