Early life and career

Not much is known of Halsey's early life in the Silver timeline, but she had worked on the planet Onyx in her early days as a UNSC scientist. She later entered a romantic relationship with Jacob Keyes, with whom she had a daughter, Miranda, but due to her focus on her work as a UNSC scientist, Halsey's relationships with both Jacob and Miranda soured.

Personality and traits

Help.png This section needs expansion. You can help Halopedia by expanding it.

A brilliant but overly ambitious scientist, Catherine Halsey is devoted to the advancement of humanity, but will often use unethical means to achieve it, such as using and killing a live clone of herself to create Cortana, kidnapping and enlisting children against their will into the SPARTAN-II program before wiping their memories and subjecting them to horrific augmentations, and attempting to replace the human consciousness of the SPARTAN-II's with AI to make them "more controllable", as she attempted to do with John-117 and Cortana. This eventually put her at odds with ONI, the UNSC, and even with her SPARTANs when they discovered the truth of their upbringing and her ultimate intentions.

Despite her seemingly cold and unfeeling exterior and tendency to see things through a purely scientific viewpoint, Halsey was not without affection, as she was devastated by Jacob Keyes' death on Reach and still cared deeply about the well-being of her daughter and the SPARTAN-II's.

Production notes

Catherine Halsey in Halo: The Television Series is portrayed by actress Natascha McElhone.[1] McElhone was originally cast to play both Halsey and Cortana, much like Jen Taylor did for Halo 4, Halo 5: Guardians, and Halo Infinite. However, due to scheduling difficulties caused by the COVID-19 pandemic, McElhone was unable to complete her work as Cortana, so Jen Taylor was brought onboard the project to reprise her role from the games.[2]
