Perman No. 1 functions as a superhero within a team, secretly living as elementary school student Mitsuo Suwa. He undertakes heroic missions while hiding his activities from the public, wearing a cape and mask that align with classic superhero tropes. In a specific conflict, he allies with characters from another series to combat an extraterrestrial threat: an alien egg that transforms into the destructive monster Jippō, confronting this danger and the enigmatic Miracle Egg through collaborative effort. As a recurring protector in media like the films *Perman: Birdman ga Yatte Kita!!* and *Pa-Pa-Pa The★Movie: Perman - Tako de Pon! Ashi ha Pon!*, he consistently battles unusual and supernatural challenges.
