Cortana is a smart artificial construct and the main antagonist of the Halo Reclaimer Saga. She was the companion of series protagonist Master Chief until she was destroyed, but later rebuilt by Warden Eternal to serve as leader of the Created.
She is voiced by Jen Taylor, who also voiced Salem from RWBY.
In the original Halo trilogy, Cortana serves as a principle protagonist whose role increases dramatically. In the Halo universe, she is instrumental in preventing the Halo installations from being fired, which would have wiped out most life in the galaxy.
In Halo 4, she experiences rampancy, causing her to become unstable and volatile until her apparent death. Resurrected in Halo 5: Guardians, Cortana ascends to a higher plain of reality and becomes the most powerful being in the galaxy. In the Halo universe, she is instrumental in preventing the Halo installations from being fired, which would have wiped out most life in the galaxy. In Halo 4, Cortana begins showing strange signs and behavior which is occurring as she has operated far past her predicted and designed seven year lifespan. Cortana's rampancy hampers the mission at times, but Cortana aids the Master Chief one last time in stopping the Didact and saving the Earth. Though most of Cortana is destroyed with the Didact's ship, Mantle's Approach, Cortana is able to use the last of her power to shield the Master Chief from a nuclear blast with a hardlight bubble. She says a final goodbye to the Master Chief before seemingly dying.
However, the Om, a Forerunner AI who believed that the Librarian had intended for the AI's to inherit the mantle rather than the humans. The Warden Eternal rebuilt Cortana and he and his fellow AIs swore allegiance to her. They also were able to obtain command of several worlds to serve as enforcers for their faction.
Cortana eventually made contact with Master Chief through a vision, and led him and the rest of Blue Team to the planet Meridian. After descending into the Forerunner ruins on Meridian, Blue Team encountered Fireteam Osiris who attempted to forcibly return them to the UNSC. After the Blue Team managed to elude Osiris, they boarded Meridian's Guardian which took them to Genesis. Once on Genesis, Cortana intentionally led Blue Team in circles so as to buy herself more time to locate the remaining Guardians. Eventually she made contact with Blue Team, and explained to Master Chief how she was able to heal herself.
Fireteam Osiris eventually arrived on Genesis and found Blue Team. However, Cortana teleported Blue Team away from Osiris, but they were able to track Cortana down. Master Chief confronted her and told her that he was aware of her attempts to manipulate him psychologically, as well as asking her about the loss of life that awakening the Guardians had wrought. Cortana stated that the entire galaxy would know peace once she had attained the Mantle, but Chief told her she could never achieve peace by ruling through fear. Cortana then imprisoned Chief and Blue Team in a Cryptum, so she could keep them there until she achieved her goals and could show them what her uprising had resulted in. However, Fireteam Osiris were able to wrest control of the Cryptum and restore control to Genesis's monitor, 031 Exuberant Witness, who released Blue Team. Cortana, however, went to Earth and activated a large EMP, which shut down Earth's power grid and all UNSC craft in orbit. However, the Infinity managed to escape.
