Assimilation profiles were computerized records maintained by the Borg, containing biographical data of individuals assimilated into the Collective.
In 2376, Seven of Nine managed to salvage the assimilation profiles of Icheb, Mezoti, Azan, and Rebi, four adolescent drones whom the crew of the USS Voyager had rescued from a derelict Borg cube. The profiles revealed their names and some other limited biographical data. Seven presented these profiles to the children as a way to assist in their transitions back to individuals.
