Christina Landgraab is an elderly woman and the mother/creator of clones Chris, Chrissie, and Christa. She is excitable, family-oriented, a genius, a heavy sleeper, and is very childish. Her lifetime wish is to be surrounded by family, which can be accomplished if she has two more children and raises them to teenagers. Due to her old age, she would either have to clone herself again or adopt to complete her lifetime wish. It should be noted that cloning in-game is only possible through the clone voucher lifetime reward from The Sims 3: Generations expansion pack.
Christina works as a top secret researcher at The Perigee and is known as a brilliant, self-centered scientist. She has long light blonde hair, gray eyes, and pale skin. Christina has a white tank top with blue polka-dots, a blue skirt with white polka-dots, white gloves, and blue shoes. She dresses with the same style and has the same favorite things (turquoise, key lime pie, and classical music) as her children to emphasize the fact that they were cloned.
Christina and her family live at 139 Avenue of the Asteroids in Lunar Lakes. They live in a large, expensive house. She is likely a descendant of the Landgraab dynasty, because she shares their wealth and last name. It is possible that Posie Landgraab, who is buried in Moon's Shadow Graveyard, is her mother, but they are not linked to one another in Christina's family tree.
- All of her children have been given different diminutives of her first name.
- Christina is one of two scientists in The Sims series to have cloned herself. The other is Loki Beaker.
