Perman No. 2, alias Booby, is a chimpanzee superhero recruited by Birdman, an extraterrestrial galactic peacekeeper. Chosen to champion human-animal equality, Booby assumes the codename Perman 2. Though lacking human speech, his expressive gestures and creative use of objects convey complex ideas to fellow Permans, showcasing advanced cognitive abilities.

Originally depicted as a zoo resident who covertly undertakes nightly superhero missions, later portrayals reimagine him as a household pet residing with an elderly couple, streamlining his crime-fighting engagements. As a team player, he supports human allies in crisis resolution and occasionally spearheads operations with animal cohorts, balancing leadership and collaboration.

In the crossover film *Ninja Hattori-kun + Perman Chō-Nōryoku Wars*, Booby joins fellow Permans to confront the villain Psychoman, aiding in the rescue of a psychic girl and disrupting a worldwide domination plot. His strategic role in coordinated clashes highlights his tactical acumen. The character exemplifies interspecies collaboration by merging human and animal approaches to challenges.

Booby’s portrayal remains steadfast across adaptations, anchored in loyalty, ingenuity, and non-verbal interactions. Spin-offs and extended media preserve his core identity as the Perman team’s non-human cornerstone, adhering strictly to his established narrative parameters.
