Peasuke Soramame, nicknamed Piisuke, resides in Penguin Village as a central supporting figure in the *Dr. Slump* series. The youngest sibling of Taro Soramame, he belongs to the Soramame family alongside parents Kurikinton and Mame. Despite reaching adulthood, his height remains fixed at 102 cm, fueling insecurities about his youthful appearance. His trademark cat-ear hat, frequently mocked by Taro for undermining his "coolness," persists as an unchanging wardrobe staple. Initially introduced as a seventh-grade classmate of Arale Norimaki and Akane Kimidori under Midori Yamabuki’s teaching, he bonds closely with them. Timid and gentle by nature, he contrasts sharply with Taro’s rebelliousness yet idolizes his brother, striving to mirror his confidence. His struggles to reconcile his childish physique with aspirations of maturity form a recurring arc, exemplified by his crushed hopes upon learning from Senbei Norimaki’s Future Camera that his height would stagnate for ten years. Pivotal experiences shape his journey: time-travel escapades with Senbei and Arale lead him to aid a prehistoric ancestor and recover a dinosaur egg that births Gatchan. Romantic growth emerges through his bond with Hiyoko, culminating in marriage and a future son, Poosuke. Cross-universe expansions see him appear in *Dragon Ball* media, including a *Dragon Ball Super* Episode 69 cameo as Arale visits the Coffee Pot. Adaptations diversify his portrayal: the 1997 *Dr. Slump* remake outfits him in a gray animal hat and depicts a failed attempt to ride Goku’s Flying Nimbus. He surfaces in *Dragon Ball Heroes: Victory Mission* alongside Taro and Akane during a tournament cameo and features in a GU clothing commercial live-action spot, standing beside them as Arale models outfit changes. Though included in *Dr. Slump & Arale-chan: Hoyoyo! The City of Dreams, Mechapolis* anime credits, his specific role remains undocumented. Across all narratives, his arc traces a path from self-conscious youth to devoted family man, retaining his timid core while adapting to Penguin Village’s eccentric chaos.
