The main user of the Hopper Memory was the mysterious "Grasshopper Woman" (イナゴの女 Inago no Onna), a hitwoman who works for the Museum as one of its top two eliminators along with the Smilodon Dopant, originally a normal girl until her mind was rewritten by neuroscientist Satoshi Yamashiro who was kidnapped to serve as a Museum researcher. She has purple hair, is dressed in Gothic Lolita attire, and carries a heart-shaped box full of boiled grasshoppers (いなごの佃煮 inago no tsukudani) that she eats and offers to others, often before attacking with her electroshock boots if they turn her down. As the Hopper Dopant (ホッパー・ドーパント Hoppā Dōpanto), she is able to jump and kick with great intensity. She is called upon by Ryubee to murder Yamashiro when he escapes from the Museum. After mortally wounding Yamashiro, the Hopper Memory is destroyed through Kamen Rider AccelTrial's Machine Gun Spike Maximum Drive. Before Ryu can arrest her, the girl attempts to escape when the Smilodon Dopant kills her so she can not reveal any sensitive information concerning the Museum.
Hopper Dopant was also one of the kaijin who gathers at Eiji Hino, Kotaro Nogami and Ankh/Momotaros's public execution. But however, when all the Kamen Riders started appearing and fighting Shocker's forces, Skyrider fought against her.
