Xenomorphs, like the creatures in the Alien series, are terrifying and deadly opponents capable of taking out human opponents without difficulty. However, it is often difficult to determine how capable they are based on the movies (especially given the different interpretations between and within various movie franchises). I think that the following would represent a decent template for a xenomorph though:

Xenomorph Worker [275]

The Xenomorph Worker is a powerful alien threat whose primary job is to gather food for the Hive, to capture reproductive vessels for the Hive, and to maintain the Hive. Making up a minimum of 90% of the Hive, they are likely the first Xenomorphs encountered by characters. While they are extremely dangerous, they lack the intelligence for strategic and tactical thinking, though they are intelligent enough to retreat to the Hive to report on their findings if they encounter something that they cannot deal with through brute force.

Notes: Workers (also known as Drones) may be capable of evolving into higher castes within the Hive depending on the needs of the Hive. While Workers have only a basic intelligence, the higher castes will often have progressively higher levels of intelligence (sometimes, though not always, corresponding to greater size).
