2. The Xenomorph Is Fear of Sex
Screenwriter Dan O'Bannon, artist H.R. Giger, and director Ridley Scott infused this alien with so much psychosexual baggage Fox was initially worried about even showing it to people. The head is phallic. Various facehugger and egg openings are vaginal. Its life cycle is riddled with rape metaphors. It's no wonder this thing is still getting under people's skin so many years after it was created. It's a walking violation of human sexual sovereignty.
