Malevolence

Malevolence (・汚れ) is a term used in Tales of Zestiria.

Description
Malevolence appears as a purple, bubble-like substance that infiltrates a being such as a human, a seraph, or an animal, which, with enough malevolence, could transform the carrier into a hellion. The level of malevolence corrupting a person or vessel's body determines what type and strength the being will become and receive once transformed into a hellion. Malevolence is impurities born from the negative emotions of humanity, ultimately threatening the existence of humans and seraphim. In some locales, it is visible as a purple particle moving horizontally.

All animals infected with malevolence could transform into a mythical being from inspired legends and mythology, or a more powerful and elder form. Examples include a bird transforming into a harpy or a dog into a werewolf. Important factors such as environment, lifestyle, relationship, temperature, feelings, and emotions determine the appearance of a human or seraph, unlike an animal, which will simply further evolve or mutate. There are also fixed-gender hellions. Some examples include Medusa, Echidna, and Succubus hellions, all of which can only be derived from a female human or seraph.
