The Franchise in general:
"In space, no one can hear you scream."
—Tagline of Alien
"Every species have a right to exist. But these... they're a disease. They exist only for annihilation."
— Superman, Superman/Aliens II: God War
"This is Alien. You are with Sigourney Weaver aboard the spaceship Nostromo. Something has gone wrong — one-by-one the crew has vanished. And somewhere in the ship, a terrifying creature waits to claim its next victim. WARNING: REMAIN IN YOUR VEHICLE. The area you are entering is extremely dangerous. Proceed with caution."
— Narrator, The Great Movie Ride
"One of the great joys of Alien was that, when they land on LV-426 th-they come across this alien planet, they land on this planet and there is an alien spaceship that they don't know anything about and there is an alien race that they don't know anything about. All they know is that a parasitic creature has apparently killed everyone on that ship, and the parasitic creature then makes its way onto humans. They're the next thing that's in the line. And there's a brilliant kind of intersection, it's just like a random thing ... And now what we've got into is a cycle of movies that are about the backstory, which actually isn't even what Alien is about. It was never about that. It was some brilliant sense of coincidence."
— Mark Kermode, elaborating on Fan-Disliked Explanation and Doing In the Wizard in his ''Alien: Covenant'' review
Alien:
Ripley: How do we kill it Ash? There's gotta be a way of killing it. How? How do we do it?
Ash: You can't.
Parker: That's bullshit.
Ash: You still don't understand what you're dealing with, do you? A perfect organism. Its structural perfection is matched only by its hostility.
Lambert: You admire it.
Ash: I admire its purity. A survivor... unclouded by conscience, remorse, or delusions of morality.
Ash: You can't.
Parker: That's bullshit.

Dallas: [looking at alien skeleton] Alien life form. Looks like it's been dead a long time. Fossilized. Looks like it's growing out of the chair.
[climbs up for a closer look]
Dallas: Bones are bent outward, like he exploded from inside.
