K-Series

The K-Series Xenomorphs are a breed of xenomorph captured and bred by human scientists hoping to use them as bio-weapons. They are also known as Yellow Xenomorphs, because of the color of their exoskeleton.

History
The K-Series created by Dr. Kadinski eventually escaped from the human lab, and used the humans as hosts. They constructed their hive within the lab.

Their species was destroyed by the "regular" black Xenomorphs, who did not tolerate the new genetic strain to preserve the purity of the Xenomorph genome.
