Parasitic Link with Host: The Embryo develops by stealing genetic materials from the host, and so its growth is dependent completely on the host. Once the face hugger has detached the host may experience various symptoms of the embryos presence: intense hunger, minor chest pain, and difficulty breathing. Alien Adults and Queens can detect an incubating embryo by pheromone changes in the host, and will not attack them.

"There's a monster in your chest. These guys hijacked your ship, and they sold your cryotube to this... human, and he put an alien inside of you. It's a really nasty one. And in a few hours, it's gonna burst its way through your rib cage, and you're gonna die. Any questions?" -Ripley (from Alien Resurrection)

Very little is known about the Alien Embryo, primarily because it is such a small stage in Alien development, and spends relatively little time inside the host. The Embryo grows from a Zygote, planted deep in the throat or breathing orifice of the host by a Face Hugger. In humanoids it later migrates to the host's chest or upper abdominal area. At this time the Embryo absorbs genetic materials from the host to allow it to grow and develop. Growth period from Embryo to Chestburster phase is usually more than a few hours.

The Embryo is vulnerable during this period, and survives by growing quickly and quietly often unknown to its host. Severe taxation of the host's strength and endurance, among other bodily processes, will slow the growth of the Embryo and hold off the Chestburster phase temporarily.
