Rebecca is the shipboard AI of the UNSC Red Horse.[1]


Rebecca is commissioned by the Office of Naval Intelligence to monitor the Red Horse during a top-secret mission around the ruins of Installation 04. She replaced the Red Horse's former shipboard AI, Chauncey.[1]


She is one of two known AI to have an avatar with two different, interchangeable appearances. Her first appearance is described as "half-Athena, half-Ares" with a feathered Greek headdress and ancient armor.[1] She could change her appearance to a flabby, middle-aged Mediterranean woman in a flower dress.[1]
