The Xenomorph species has been a complex design through the use of biological engineering, genetic experimentation, cross breeding, and hybridization. Dr. Gloriosa Daisy has been working for 10 years on experiments based on her own design, thanks to the geodes she managed to find deep in the cave of the Everfree quarry. It had taken many different experiments to try to understand what geode was compatible, and which wasn't. Once she was finished however, she would in turn betray the U-Y Corporation and sell them to a secret military organization.
