Ada

Ada is a modified Assaultron living in the Commonwealth in 2287 and a possible companion of the Sole Survivor.

Background
Ada is a heavily modified Assaultron robot with sentry bot and Protectron parts. She was created by Jackson and traveled with his caravan, which specialized in mechanical repairs and trade, throughout the Commonwealth. Jackson's caravan attracted the attention of the Mechanist and after three attacks, every member of the caravan except Ada had perished. Ada is first encountered during the quest Mechanical Menace during which the Sole Survivor must help Ada eliminate the robots that attacked her caravan. She is encountered just northeast of Wattz Consumer Electronics when her caravan is attacked the third time.

Appearances
Ada appears only in the Fallout 4 add-on Automatron.

Behind the scenes
Ada's line "resistance is futile" is a reference to the Borg in Star Trek. After using a terminal, Ada may say "Using a keyboard. How quaint," a reference to a similar line from Mr. Scott in Star Trek IV: The Voyage Home. Another one is found during Restoring Order when she mentions "It feels like: Poetry in motion," referring to the popular song by Johnny Tillotson in 1960. She will also say, "If you don't eat your meat, how can you have any pudding?" in any school location. This is a reference to Another Brick In The Wall, Part 2 by Pink Floyd.
