"It looks like damage."
Using a delivery method similar to a Facehugger, the Predalien birthed from Scar in 2004 could force embryonic Xenomorphs down its victim's throats. The victims appeared to be only pregnant females, as the Predalien merely killed a female nurse instead of implanting her. The implied reason behind this is so that the baby Xenomorphs could feed on the human fetus before taking its place in the stomach. Multiple larvae later erupted from the victim's abdomens. Functioning as a juvenile Queen, the Predalien utilized these multiple spawnings to quickly increase the Xenomorph population and build the Hive in mere hours, presumably before molting into a full grown, Egg-laying Queen.
How this method of reproduction works is unknown, as with regular Facehuggers, it is strongly suggested that a cancer is deposited to force the body to grow an embryo. However the Predalien's method clearly shows what seems to be actual embryos being deposited.
Bellybursters also make a minor appearance in Aliens: Labyrinth, in which Paul Church encounters an incredibly bloated Louise Clark being crowded by Xenomorphs inside a hive. She later gives birth, with four Xenomorph infants bursting out of her stomach. These bursters however are different to the ones in Requiem as they are severely deformed and later die.
Behind the scenes
- "The belly bursters were actually in the first draft that Colin and I read...They had the bellybursters ... caused by an alien warrior...We actually made it the Predalien that was reproducing in this fashion" -Greg Strause AVP-R: Preparing For War: Development and Production (featurette)
- "Basically the Predalien's kind of a baby queen-there's a phase in between warrior alien and full-blown queen...they do this thing with embryo implantation.. the idea with that was; how does a baby queen quickly form her own little mini-drone army to get the hive built before she evolves into the final state where she can't completely defend herself?"--Colin Strause AVP-R: Preparing For War: Development and Production (featurette)
- In reality, Bellybursters seem to be more or less identical to traditional Chestbursters, the only difference being their different gestation characteristics.
- Chestburster — A more common embryonic Xenomorph form that differs in its gestation and birth characteristics.
