Cortana is a prominent artificial intelligence (AI) character in the Halo video game franchise, developed by Bungie and 343 Industries. Initially created as a companion and guide for the Master Chief, Spartan-117, she serves as a vital source of tactical information, hacking capabilities, and strategic planning throughout their missions.

Her genesis stems from the brain scans of Dr. Catherine Halsey, a brilliant scientist and creator of the Spartan-II program. This process imbued Cortana with a remarkable intellect, complex personality, and capacity for independent thought, blurring the lines between AI and genuine consciousness.

Throughout the series, Cortana's relationship with the Master Chief evolves beyond mere partnership, developing into a deep bond of mutual respect and affection. She frequently questions her own existence and mortality as an AI, grappling with the concept of "rampancy," a terminal degradation of AI mental function. Her ultimate sacrifice to save the Master Chief and the galaxy solidifies her place as a central figure in the Halo narrative.
