Cortana/Silver

Cortana is an artificial intelligence in the United Nations Space Command.

Creation
In 2552, Dr. Catherine Halsey attempted to get Vice Admiral Margaret Parangosky's permission to create Cortana without any success. Nevertheless, Halsey secretly cloned herself at least once against orders. While visiting Halsey's lab following the Attack on Madrigal, Parangosky spotted the flash clone and berated Halsey for her actions. Parangosky ordered Halsey to destroy the clone and any others that she might have made. Later, as John-117 started to go rogue, Halsey again tried to get the Admiral to approve "the Cortana system" without any success.

Production notes
Cortana in Halo: The Television Series is portrayed by Jen Taylor. Natascha McElhone was originally cast to play both Cortana and Catherine Halsey, 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.
