Unusually quiet, Marie is less than a year old and in perfect health. The offspring of Ashur and Sandra, her conception occurred after Sandra set up her laboratory in a wing of Haven. Over time, the couple have come to honestly care for each other, and the safe birth of their child is considered nothing short of a miracle - one they intend to use for the benefit of their city.
Marie was born with a natural resistance to radiation and Troglodyte Degeneration Contagion, and because of this unique gift she has been studied by her parents to find a cure to help with the constant radiation in The Pitt.
She weighs 5 pounds and teddy bears are her favorite toy.
At one point in development, a Pitt slave named Beth would intercept the player character, should they choose to kidnap Marie. Beth would proceed to take Marie from the Lone Wanderer and to Midea's quarters.
Marie appears only in the Fallout 3 add-on The Pitt.
