Deathworm

Deathworms (デスワーム Desuwāmu) are sapient creatures living in underground and come out for hunting only non-sapient animals.

Unlike in that TV show, Uchu Sentai Kyuranger, they are not aggressive nor evil, so instead they are peaceful and gentle to all sapient species and beings, except to vampires due to bloody conflicts with them. They are omnivores that feed on the same food as many other sapient species and sapient beings.
