The Legend of Zelda: March of the Iron Army
We haven’t been able to piece together much about this computerized researcher from another universe, but as best we can tell, she was built to oversee the functions of a corporation called Aperture Science. The artificial intelligence at her core was apparently once human, patterned after the mind of a woman identified only as Caroline. While the laboratory was clearly capable of highly advanced wonders, capable of rivaling great magic with her science, GlaDOS’ thought processes became corrupted over time and she responded with barely-covered hostility towards organic beings. She seemed particularly focused on tormenting a young woman who ‘killed’ GlaDOS at some unspecified point in the past before escaping.
Of particular interest to GlaDOS were wormholes and the use of portal technology to connect two wormholes together, a technology that Cheren has now incorporated into her own arsenal.
