Hopper is a Grasshopper Fairilu, originally designated a Legend Fairilu in the franchise's first two seasons. His appearance features a pale yellow-green color scheme. During these early seasons, he worked as a Shaborilu coach and physical education teacher, while also participating as a soccer player; his interests included the sport of Shaborilu. His name reflects his grasshopper insect motif.

In the third season, "Tell Me, Magical Pendulum ~Rilu Rilu Fairilu~," set in a parallel universe, Hopper undergoes a significant change. He appears in a child form and is reclassified as a Bug Fairilu, distinct from his prior Legend status. He joins the friend group centered around Lip and her companions, interacting with both Fairilus and humans accessing the Fairilu world via the Magical Pendulum device. This version of Hopper sports piercings and wings consistent with other Fairilus.

Regarding relationships, Hopper was respected by other Fairilus; Jasmine, a Jasmine Fairilu, developed romantic feelings for him upon their first meeting. His earlier roles involved mentorship and coaching positions, indicating a leadership aspect prior to his transformation.
