Mama is the name of an artificial intelligence residing on the planet Cronkee. She protected a small group of humans living there, and lived in a crashed UNSC Frigate. She was described by Cortana as being "happy" and "something of an antique." A comment made by one of her "children" suggests that she once fought off a group of Kig-Yar pirates that attacked them.
