FN-1226 was a stormtrooper of the male human species. He was a member of the FN Corps within the First Order during the year 35 ABY. During Rey's mission to save Chewbacca aboard the Star Destroyer known as Steadfast, the Jedi employed a mind trick that bewildered FN-1226 as well as another stormtrooper.
The 2019 Star Wars movie Star Wars: Episode IX The Rise of Skywalker marked the initial appearance of FN-1226. J.D. Dillard, a screenwriter and director who had previously collaborated with J.J. Abrams, portrayed the character.
