Phase one - Egg, A soft pod that contains Phase two of Xenomorph Development
Phase two - Facehugger, A Spiderlike creature with a tail that implants an Embryo into the throat of the being it latched onto*, It's tail wraps around, and constricts the throat, so as to cause the victim to lose conciousness. Then, To prevent host death, It gives the host small amounts of oxygen from two sacs behind the legs of the Facehugger. Once the embryo is implanted, it sinks down into the upper chest of the host, where it gestates. As
soon as the Embryo loses touch with the implantation 'tongue' of the facehugger, the facehugger detatches and dies. Then the Embryo grows into Phase three.
Phase three - Chestburster, The Production of the embryo, it's
name comes into play when it is fully grown. Where it digs/eats it's way through the hosts internal organs,
bones, and chest, and 'bursts' out. Depending on the host, the Xenomorph may be of varied sizes immediately after birth.
Human and Yautja Borne-Xenomorph chestbursters are relatively small, but Dog and cat, and soforth borne Xenomorphs grow until they no longer fit in the host's stomach, then they 'burst'. The Chestbursters gnerally take familiar traits from the host Humans 'give birth' to Xenomorphs with Humanly capabilities, such as Bipedalism. Once a Chestburster is born, It immediately looks to feed, once it has done so, It sheds it's chestburster skin and fully grows into Phase four.
Phase four - Fully-Grown Xenomorph, Having fed and grown, It meets it's final stage of life. Now that it has inherited all the traits it needed to grow, It no longer changes. Depending on the physical abilities of the host, now factor into it's job in the colony. If it was born from a Marine, It would grow as a Warrior or a soldier, If it was born from something that was unemployed, or a working class person, It would be a Drone, a worker. Usually Xenomorphs born from lower life forms, such as
dogs and cats, Are used as scouts and runners. Yautja-Borne Xenomorphs are usually cast out, or left unused by the Queen.
Classes of Xenomorphs
Drones#1: Singular Drones, Usually cast out, or first-births**, They aren't used to Hive
work, and usually make their own mock hives, for
food.
Hive Drones#4/
5: Drones are workers, they secrete the hive. They follow the exact orders given to them, even if it includes harming the queen. They will also harm others of theirs, if it is necessary to follow the queens orders.
Runners#3: Lower-births**, they are sent out to
scout out more places to expand the hive, and report to the queen, as she is immobile. They have thinner
bones, but stronger appendage muscles*** To help them run. But as it also seems, it helps them capture prey if necessary.
Soldiers#6: Extremely powerful muscles, and thicker
bones, to make them powerful to destroy, But it also slows and weighs them down. They are not protectors by any means, They are sent to make war against deadlier threats. Usually they aren't even birthed, because the Xenomorph's usually assimilate everything, instead of destroy it.
Warriors#2: The bridge between drones and Soldiers, They protect and fight for the queen. They have thicker
bones and stronger muscles, but not as thick or strong as the Soldier, to balance them out.
Prætorians -
seven are born, and protect the queen, nothing else. They are born after the queen, but live much longer, to protect the queens final-laid egg, her successor. They die out after the Praetorian eggs are born. They are bigger, stronger, somewhat undersized queens. They have powerful, small arms proof, skin.
Queens#2/4/
5 - The Largest Xenomorph, one of it's kind is birthed to a hive from the previous one. This is the complete Schbang, she gives birth to the eggs, and orders all of the Xenomorphs born, ALL OF THEM. She is secreted to an Egg chamber, where the Eggs come out from. However, if the situation calls for it, she can detatch from the egg laying device. Since she is noramlly secreted to the wall, she has little balance, and stutter-steps around when free.
*-Queens and Prætorians have their own Special Facehuggers
**-Born before a queen, casting them out of a hive.
***-Born from a lower creature, like a cat, or a dog, or an Ox.
