The Hyena-Swine was one of Dr. Moreau's creations. Of all the Beast People, he was the most vicious. Part hyena and part pig (as his name suggests), he was something of a rabble rouser and constantly pushed for increasingly harsher punishments for breaking the Law. After Moreau's death, the Hyena-Swine became the unofficial leader of the regressed Beast Men. He killed Edward Prendick's friend the Dog Man, and was subsequently shot and killed by Prendick himself.
