Alien: Romulus

A full-grown xenomorph abducts Kay, dragging her into a nested section of the station. She is especially vulnerable — her pregnancy makes her a viable host, and Z-01 exposure begins accelerating what is growing inside her. Rain and a compromised Andy fight their way through the station to reach her. Tyler is killed in the process, impaled in a tight corridor while covering Rain's escape. They pull Kay free and recover a Z-01 sample, nominally completing Rook's mission objective — but the station is now drifting toward LV-410's asteroid ring and coming apart under the structural stress.

In a standout sequence, Rain and Andy cut gravity during a fight in an elevator shaft — blood and spent casings float, xenomorphs flail, and they scale the shaft before restoring gravity and dropping the elevator down onto the cluster below, crushing several aliens at once. Andy lines up the last one and fires, an echo of Ripley's famous line landing with enough earned weight to feel like tribute rather than imitation.

As Renaissance tears itself apart in the asteroid field, Rook and his remaining lab data are destroyed with it. Rain, Andy, and Kay make it back to the Corbelan IV and detach just in time, setting course for Yvaga III. For a moment it looks like a clean escape.

It isn't. Kay has been exposed to Z-01 throughout, and its DNA-rewriting properties accelerate her pregnancy into something unrecognizable. On the ship, her belly swells rapidly, she convulses, and what she delivers is not a child — it is a fleshy facehugger-like egg that opens almost immediately. From inside emerges the Offspring: a human-xenomorph hybrid, humanoid in proportion but unmistakably predatory — pale, elongated, laced with xeno traits, and furious. It kills Kay. When Andy moves to intercept, it slashes his neck and partially disables him, leaving Rain effectively alone on a small ship with something that has no frame of reference for its own existence except rage.

Rain suits up. In a sequence that deliberately mirrors Ripley's endgames — working the ship's tight corridors and airlocks, using decompression and doors and whatever she can reach — she fights the Offspring back toward the hull. The creature is hard to put down, shrugging off damage with the resilience of a xenomorph, but Rain lures it to an exterior hatch and blasts it into LV-410's asteroid field, where it is torn apart. The last thing that enters space from the Corbelan IV is something that was never supposed to exist.

Rain puts Andy in a cryopod and tells him she will fix him when they reach Yvaga III, even knowing the planet has banned synthetics. She records a final voice log — identifies herself as the last human survivor of the Renaissance incident, notes that she has denied Weyland-Yutani its specimen and its data, and sets course for a world outside the company's reach. Then she seals herself in her own cryo chamber, and the ship drifts toward Yvaga III in the dark.
