**Geroppa is a frog who seized command of a space station following the human crew's evacuation. Driven by a violent and ambitious nature, he consumed most of the remaining insect inhabitants and supplies, growing dissatisfied with the station's provisions. This fuels his relentless pursuit of living prey, specifically targeting Midge's escaping insect group. Physically, Geroppa possesses a sturdy build and wears an eye patch, amplifying his imposing and dominant presence.**

**He commands henchmen frogs, including the nervous and careless Itou, and the less intelligent but combat-skilled Katou, who wields a cotton swab as a weapon. Geroppa also repurposed the support robot Doctor Humpdy, originally designed for humans, reprogramming it to serve his faction; the robot demonstrates loyalty despite its nature.**

**Geroppa's primary motivations are profound boredom and intense hunger, compelling him to capture and consume the fleeing insects. His leadership style emphasizes dominance and control, viewing himself as the station's ultimate authority. This ambition directly positions him as the antagonist to the insect protagonists during their escape journey.**
