FN-1971 identified a human stormtrooper serving within the First Order's FN Corps. This particular stormtrooper would secretly provide comic books based on the animated show, Kade Genti, Master of Section Nine, to a younger stormtrooper, FN-2187, for his enjoyment. Both knew these actions violated protocol and could result in reprogramming if discovered. Later, in 34 ABY, FN-2187, who had become "Finn" and joined the Resistance, recalled reading the comics from FN-1971. He then decided to use the name of the show's main character, Kade Genti, as a false identity while infiltrating an auction taking place in Coronet City on the Corellia planet located in the Core Worlds.
The 2019 novel Resistance Reborn, penned by Rebecca Roanhorse, included a mention of FN-1971. The designation of this character aligns with the birth year, 1971, of Roanhorse.
