Ovomorph



Eggs are the initial stage in the lifecycle of most Xenomorphs. They are laid by queens and are vital to the survival of the species.

Appearance
These eggs stand two feet tall, maybe a bit taller and are a leathery brown color. They are pink in the inside, with many veins and membranes. The egg has four 'petals' that open when the contained head crab senses prey, and possess a specily adapted toungh that feed the Facehugger nutrients until this happens.

Abilities and Mannerisms
Eggs can sense suitable nearby prey through unknown means, and will open upon doing so. They are able to identify whether a host is suitable through an unknown means, possibly through the detection of movement or body heat. Despite their roots, eggs cannot get around themselves and rely on adult aliens to move them into positions where they can strike.

Development
Eggs develop in 3 different ways.


 * Praetorian Egg: Normal eggs can cocoon themselves and molt into Praetorian eggs which hold Praetorian Facehuggers.


 * Swollen Egg: In the game Alien vs. Predator: Extinction a Queen could lay eggs that contained up to four facehuggers, depending on the number conditions of the hive, further proof of the Alien's adaptive evolution.


 * Swollen Praetorian Egg: A Swollen egg also features in AvP:E. It holds one Praetorian Facehugger while the rest are just normal facehuggers.
