The Pterocetus, also commonly known as "big-mouthed dog" or "Spawn of Despair", is a creature that seems to come straight out of hell. It is said that his appearances on Earth would precede apocalypses. The Pterocetus is asexual, but it has the ability to give life. After eating well, he vomits a Pterocetus fetus still in his amniotic sac. After that, the Pterocetus abandons its offspring, which will quickly become independent, and which will reach their adult form in a few days. The Pterocetus lives mainly in volcanic or arid environments. But he does not hesitate to move to more urban environments to be able to feed on fresh flesh.
