Carlyn Williamson (Earth-7149)

"GEDIMAN!"

- - Dr. Carlyn Williamson

Dr. Carlyn Williamson was an anesthesiologist and member of the seven-men scientific team of the Weyland-Yutani Corporation stationed aboard the UNSC Auriga as a part of Project OZYMANDIAS, a secret joint scientific effort between the Weyland-Yutani Corporation and the UNSC to clone Ellen Ripley and acquire xenomorph specimens.

Researching Ripley 8
"Hand... Close. Glove."

- - Ripley 8 and Dr. Carlyn Williamson Williamson was one of the many scientists who witnessed the surgical removal of the Queen Chestburster from Ripley 8, something which she did personally by taking the creature out of the laboratory room after the operation. Once Ripley 8 regained consciousness, she attacked and broke the arm of Dr. Dan Sprague while he closed her incisions, prompting Williamson to tend for Sprague's injuries. She later helped to study Ripley 8, running a series of images that showcased the genetic intelligence she inherited from both the late Ellen Ripley and the xenomorph DNA within her, to the point the clone was able to recall Ellen's memories, including having faced the xenomorphs before and the existence of Rebecca "Newt" Jorden.

Once the Betty arrived in the Sol system and docked with the UNSC Auriga, Dr. Williamson observed as the kidnapped colonists were imprenated by Facehuggers, something which she was visibly distressed and physically sick about after witnessing the brutality of the impregnation process. Afterwards, she continued to study the xenomorphs as they grew, leading to the first detailed scientific notes about the life cycle of the xenomorphs.

Death
She and her superior, Dr. Jonathan Gediman, were present in the observation room when the xenomorphs escaped from their containment. Gediman, horrified, entered the room with caution to investigate the xenomorphs' escape, but as he looked into the hole created by the species' acidic blood, one of the Warriors seized the scientist and pulled him into the floor to his assumed death as Williamson watched in horror. She later attempted to flee from the Auriga by escaping aboard a Class-3 Bumblebee but she was slaughtered alongside the UNSC Marines by xenomorphs that snucked into the pod.
