Thousands of years post ascension, former princess Twilight Sparkle has made quite the name for herself as the developer of the technology that led to the now numerous pony-like androids that roam Equestria. After stepping down from the throne to pursue her scientific studies, Twilight Sparkle has since left the very company she helped found, the company responsible for all current android production: CyberLife. 

Nearly half a century since leaving CyberLife, Twilight Sparkle was commissioned by the current executives to help them program a highly experimental new set of super prototypes: two RK800 models, intended as detectives able to work closely with non-androids and to investigate the growing number of cases of androids breaking from their programming and exhibiting signs of pony-like emotions.These two RK800 androids, known to the non-android world they are meant to integrate so seamlessly into as “Pinkie Pie” and “Rarity,” are rumored to have been inspired by some of the former princess’s friends some three thousand years prior — most likely the Elements of Laughter and Generosity, Surprise and Sparkler, although these rumors are unconfirmed.
