Shonen Rivals who carnivorous creatures (e.g Animals, Demons, Parasites, Aliens, Cosmic Entities, Lovecraftian Horrors, and/or Deities) who hunt and kill for food.

Oftentimes they are simple animals who play a part in their respective ecosystems, or perhaps were people who were transformed into predators but manage to control their feral instincts.

Note: This should not be entirely mistaken with human predators who are Cannibals and/or Man-Eaters if they hunt within their own species, or Perverts if they are sexual predators. This category is for creatures who have to eat other creatures in order to live, such as Animalistic Predators - however, these categories can overlap in some cases.
