Lexi Castle is a pre-made future Sim living in Oasis Landing, from The Sims 3: Into the Future. She lives with her father Nathaniel, her grandmother Susan and the family Plumbot Vroombo. She is implied to be an extremely bright and ambitious Sim, and causes some social awkwardness at school, although they bind the family tighter together. She can be made playable by asking her to move in.
Lexi is friends with all of her family members. Like all pre-made Sims from Oasis Landing, she has the Future Sim hidden trait. She has mastered her Advanced Technology skill and has 4 skill points in Laser Rhythm-a-con.
