Molly O'Brien was a resident of Gunnison, Colorado who, in 2004, became involved in the Xenomorph outbreak that ultimately led to the destruction of the town.

Molly was one of four people known to have survived the Gunnison incident, along with Dallas Howard, Ricky Howard and her mother Kelly.


Because of her mother´s long absence because of her job in the army, she had become distant to her. Her father was killed in her home by a Xenomorph during the Xenomorph infestation. She and her mother, however, managed to escape. After that they fought to survive the infestation with the help of others they met later. During that time they became close again.

She was one of only four survivors that escaped the invasion of Gunnison, Colorado. She achieved that by escaping on board of a medical helicopter, along with her mother, Dallas Howard, and Ricky Howard. By doing this she narrowly escaped the destruction of the town ordered by Colonel Stevens and was apprehended later by unknown military personnel.
