Deacon

The Deacon is an artificial sub-species of Xenomorph created by the Space Jockeys to be used as a weapon, which turns around and backfires horribly. It's lifecycle is similar, but still different compared to the xenomorphs, thus granting it's own page due to the dissimilarities.

Due to its erronous and extreme failure, it appears to have been immediately de-commisioned, as it is never seen again.

This is NOT the same species of xenomorph on LV-246, Rather, LV-223 was a facility housing prototypes of this sub-species. Additionally, this does not count into effect the evolutionary time and gap between Prometheus and Alien, which is a 30 year gap, not long enough for it to have evolved properly.
