Cortana, Allied Artificial intelligence (Service Number - CTN 0452-9), was a Smart artificial intelligence construct. She was one of the most important figures in the First Multiverse War. In addition, she held vital data pertaining to the Axis and the Coalition. Cortana had a witty and playful personality and a small sense of cryptic humor laced with some sarcasm. She had neither arrogance nor false modesty about her immense capabilities, and her statements about her abilities have an objective perspective that human beings typically cannot achieve. She did get bored often and easily.
