Corporal Cynthia Dietrich was a Hospital Corpsman with the Colonial Marine Corps. She was a member of the combat unit deployed to LV-426 aboard the USS Sulaco in 2179, to investigate the sudden loss of contact with the colony of Hadley's Hope. She was subsequently involved in combating the Xenomorph infestation at the colony.

Dietrich was part of Second Squad's rifle team, along with Private Frost. She was taken by the Aliens during the early stages of the operation, and was subsequently impregnated with a Chestburster.

Dietrich was made using NECA's Portal 2 Chell body as base, with the lower legs and armor from NECA's Hudson. Her head is from a Katniss Everdeen figure. I painted her pants to match with the rest of the colonial marines batallion.
