An Evil Alien, Johanna Watson, taking her advantage to kill a vampire at the middle of the night.
Evil Aliens formerly act as the titular antagonists of the extremely gory comedy-horror, Evil Aliens - made in a splatter style similar to Evil Dead, Braindead and other "video nasty" type horror comedies. Evil Aliens themselves are an example of demonic aliens in popular culture as they are far more malevolent than any normal species would be, to the point of being Satanic by humanity's general moral standards.
But like all kinds of demon species that were introduced on Earth, they are actually peaceful and gentle, unlike how characters of Evil Aliens once thought. They are omnivores, feeding mainly on the same food as humans. They come in many different shapes and sizes depending on a subspecies. They are not effected by religious items, unlike in mythologies. They aren't evil and only feed on live animals in case of food shortages, and despite their name, they aren't evil at all, but they are a peaceful species
