Xenomorph

Xenomorph is a species of sapient alien with an unknown ancestor. They are extremely peaceful and gentle towards all sapient species and sapient beings, unlike in movies and other pop culture (which wrongly/inaccurately showed them as aggressive and dangerous creatures), except vampires due to bloody conflicts with them. The facehugger stage of xenomorphs don't go inside any sapient species or sapient beings nor rips through anyone's chest (thus killing them), since this is only in movies. Instead, facehuggers actually go inside the parent xenomorph's face (which their parents want), as they develop into chestbursters, they rip through the adult xenomorph's chest, thus killing the adult xenomorphs in progress. They are omnivores that feed on the same kind of food as many other sapient species and sapient beings.
