Alias: Sil, Eve, Patrick Ross, Sara, Miranda Hollander, Azura

Summary: Is it not the right of all species to mate and procreate? Well, it honestly depends. If your reproduction poses a threat to literally all life on the planet, chances are there's going to be...issues...
History: It all started when humanity got its hands on alien DNA sent out to us, presumably from Mars. From there, project Athena was launched in the hopes of creating a fully-functional human from the DNA. It works...too well, as the test-tube baby, Sil, grows at an alarming rate, but feels a need to escape and mate. For the alien side is breaking out, and the last thing anyone needs is an invasion from the inside...
Notable Kills: Sil rips out a woman's spine with ease.
Final Fate: Although Sil is incinerated along with her offspring, her genes are used to create Eve, who dies at the hands of Patrick, a human who came into contact with Martian genes as well (he gets stabbed by an infected pitchfork and dies). Eve's daughter Sarah thankfully turns out to be infertile after a long string of chaos and murder, and is currently living with her boyfriend. That last one, Miranda, died saving her boyfriend from the villainous Azura.
Powers/Abilities: All of Sil's species can switch between human and alien form, as well as regenerate from almost every injury.
Weakness: Anything conventional and no immunity to diseases
Scariness Factor: 3.5-Just about every mutation here comes with a degree of horror and odd appeal. Obviously, the female beings try to put on a good look, and some are genuinely alright in the end, but they're still capable of tearing you to shreds while looking like one of H.R. Giger's nightmares (not a coincidence, by the way). But Patrick is the absolute worst, looking like a cross between a Yautja and a Xenomorph in a way that's just plain wrong.
Trivia: -H.R. Giger actually lent a hand in making this franchise, right down to Sil's true form. He had ideas for other stages of Sil's life cycle that were never used, though.
-Both Sil and Eve were played by Natasha Henstridge, the former of which was her acting debut. It is said that she was chosen for how tall and imposing she could be.
