The Beluga-Xenomorph was a Xenomorph cut from Prometheus early in its production. It was originally going to be the creature born from Charles Holloway after he was impregnated by an Octo-Facehugger from one of the molluscoid eggs found in the Temple. The creature is only mentioned in the script for an Alien prequel written by Jon Spaihts. The Beluga-Xenomorph started off as a boneless octopus-like Chestburster that is able to squeeze itself under doors and through the bars of the ventilation system. After developing further it kills several crew members before it is itself killed by Jocelyn Watts.
- The Beluga-Xenomorph should not be mistaken for the Deacon, which appeared in the finished Prometheus film.
- The Beluga-Xenomorph is similar to the White Hybrids from Aliens/Predator: Deadliest of the Species, The difference being is that white hybrids had eyes and Yautja mandibles.
