Alien Earth Episode 3 Revises Xenomorph Lore With New Tadpole Life Stage

by

In my enthusiasm for the captivating world of sci-fi, I must express my delight in the intricate exploration of the xenomorph life cycle unfolding in Hulu and FX’s Alien TV series. As a spectator, I feel like an archaeologist uncovering new findings with the introduction of the tadpole phase in Alien: Earth – set in 2120, nestled perfectly between Alien: Covenant and the original Alien film in the franchise’s timeline, marking a first for humanity’s home planet. The strategic placement on the timeline has given this series an enchanting opportunity to delve deeper into the Xenomorph’s lore, which was further amplified by the fascinating discovery revealed in Episode 3 as scientists dug into the mysteries that surround these enigmatic creatures.

In the most recent episode, the Prodigy crew retrieved the samples from the debris of the USCSS Maginot and transported them to Boy Kavalier’s (Samuel Blenkin) island. Upon arrival, Kavalier’s group, with Kirsh (Timothy Olyphant) as their leader, and the young hybrids – the only ones allowed close to the potentially harmful species – commenced their investigations by carefully cracking open a Xenomorph egg and extracting the facehugger within.

As a cinephile delving into the mysteries of Alien biology, I conducted an impromptu postmortem examination on a living specimen (a lucky break for Sydney Chandler’s Wendy, thanks to her unique abilities). Removing the contents from within the Facehugger’s body unveiled an astonishing discovery: the embryonic form of the Xenomorph – a tadpole-like creature. This fascinating revelation offers fresh insights into the legendary Xenomorph and its development, expanding our understanding of the alien species’ life cycle by revealing an entirely new stage.

In the year 2025, on August 12, the sci-fi series “Alien: Earth,” produced by Noah Hawley and featuring a talented group of actors including Timothy Olyphant, Alex Lawther, Sydney Chandler, Babou Ceesay, and Essie Davis, made its debut on Hulu and FX. Fresh installments air every week.

Alien: Earth’s Xenomorph Life Stages Explained

Ovomorph

Earth’ that these eggs can be penetrated using something sharp, like a saw. Inside, there’s a top opening that springs to life when sensing a possible host nearby.

After the incubation process is finished, if there’s a suitable host nearby, the egg can open up, releasing the Facehugger.

In simpler terms, Ovomorphs, which are usually laid by the Queen alien, can also be produced through a process called Eggmorphing. This process involves taking hosts and encasing them in resin, leading to their bodies transforming into eggs. Although Eggmorphing has not been officially verified on-screen, it was initially depicted as a deleted scene in the film “Alien”. However, it could potentially be confirmed in future Alien series or films.

Facehugger

From an ovum, or egg, emerges the Facehugger, resembling a spider-like parasite. This creature clings to the host’s face and inserts a Xenomorph embryo into their body through their throat by means of its tail. In an effort to prevent removal, it tightens its tail around the victim’s neck, and with its numerous limbs, it maintains a firm hold on the host’s face.

Resurrection”, Facehuggers are heat-sensitive, powerful, and swift, and they tenaciously chase down potential hosts.

Tadpole

In the new phase of Xenomorph life depicted in “Alien: Earth”, we encounter either the tadpole or Xenomorph larva. Although it’s long been understood that the Facehugger plants a tiny, embryonic being into its host (which later transforms into the chestburster), the ‘Metamorphosis’ episode of “Alien: Earth” marked the first time we witnessed this creature actively.

After Kirsh slices open the Facehugger, he removes a slimy, wriggling organism, similar to frog eggs. This tiny creature is then submerged by the synthetic in a container of water, where it swims and eventually burrows into a human lung, imitating the way it reproduces within a host’s body.

I can’t help but marvel at the unveiling of this extraordinary creature, expanding upon the already intriguing Xenomorph life cycle. Initially, it appears unlike any other form of the Chestburster that came before, signifying a unique transformation in its developmental stages.

Chestburster

Over a certain period, the embryo matures within its host into what’s known as a Chestburster, utilizing the host’s biological substances for nourishment and development. The type of Xenomorph that eventually emerges from the Chestburster stage can be influenced by the specific host it develops in, much like the four-legged Xenomorph seen in Alien 3, which hatched from a dog’s body.

Upon reaching maturity within the host’s body, the embryo violently emerges, causing the unfortunate demise of the host. At this developmental phase, the Chestburster resembles a smaller version of the Xenomorph, featuring a rounded skull and teeth, along with a long tail. After its birth, the Chestburster seeks refuge to cocoon itself and progress into its subsequent stage.

Xenomorph

In due course, confined within its cocoon, the Chestburster undergoes remarkable growth, eventually transforming into a Xenomorph that towers over 7 feet tall. Known as supreme predators, Xenomorphs possess several distinctive traits such as corrosive blood, retractable tails for attack, extraordinary agility and stealth, and an additional inner jaw capable of shattering enemies’ bones and flesh. However, they’ve been shown to have vulnerabilities in the film series titled Alien: Earth.

In the universe of Alien, various types of Xenomorphs are acknowledged according to its canon. The most prevalent ones are Drones, whose role is seeking out fresh hosts for the hive’s expansion. Drones can progress into either Workers or Warriors, with the former focusing on constructing and the latter primarily tasked with defending the hive. Some may advance even further to become Praetorians, who are significantly larger and mainly protect the Queen.

Queen

In the final phase of its life cycle, the towering Xenomorph Queen was first presented in the movie “Aliens”. Although only a small number of Xenomorphs reach this stage, it is considered the peak of their species. The Queens are approximately 20 feet tall and are characterized by additional limbs and a swollen torso that allows them to produce and hatch eggs.
