Puri-Puri Prisoner, an S-Class Rank 17 hero affiliated with the Hero Association, serves a 10,000-year sentence in Smelly Lid Prison for sexually harassing and raping multiple men. Despite possessing the power to escape at will, he remains voluntarily incarcerated; his presence deters other dangerous inmates, who fear his retaliation. Details of his childhood are sparse, though he took swimming lessons. Standing 7'2" with a muscular build, small afro, and unshaven face, he typically wears a standard prison uniform with an unchaining iron ball that doesn't impede his movement. He occasionally dons hand-knit sweaters from his prison boyfriend, one destroyed during battle with the Deep Sea King. His heroic actions frequently stem from romantic or protective feelings toward men he admires. Witnessing endangered heroes or civilians on television prompts him to break out, confront the threat, and return to prison afterward. For instance, during the Sea Monster arc, he escaped after seeing Stinger and Lightning Max endangered by the Deep Sea King. He fought using his signature "Angel ☆ Style" transformation—gaining angel-like wings and enhanced physical capabilities—but was defeated. Later, he offered rejected "Angel Shots" during hospital visits to Stinger and Lightning Max. In combat, he exhibits superhuman strength, speed, and durability, evolving his abilities through battles. After losing to the Deep Sea King, he developed the more lethal "Dark ☆ Angel ☆ Rush" during the Alien Conquerors arc, using it against the alien Melzargard alongside fellow S-Class heroes. His resilience withstands electrical, freezing, and sonic assaults, demonstrated against lower-tier monsters in the Monster Association arc. Absorbing combined energy blasts from the Demon-level monster Baquma, he adapted by creating "Vibration ☆ Angel," channeling bodily tremors into destructive force. Further innovations include "Angel ☆ Bristle Armor," generating protective body hair, and "Angel ☆ Crawl," enabling him to swim through solid surfaces like concrete. He employed these during the Monster Association raid to pursue the Dragon-level executive Nyan and navigate the headquarters. Severely injured by Nyan’s "Feline Retribution," he prioritized saving his monsterized former inmates, believing his "Angel ☆ Hug" and kisses could restore their humanity; most rejected his efforts, and many died. He later encountered Garou chained within the Monster Association base. Initially attempting rescue, he recognized Garou as a threat but was swiftly defeated after Garou awakened. Surviving, he informed Superalloy Darkshine of Garou’s capabilities. During the surface battle against Psykos and Orochi, he collaborated with other heroes, using "Vibration Dark Angel Rush" to damage the fused entity. He provided critical support, rescuing Child Emperor from rubble via "Angel ☆ Crawl" and relocating injured heroes like Genos and Tatsumaki to safety. An OVA episode showed him accidentally freeing Smelly Lid Prison inmates while battling a monster; to prevent a prison employee he admired from losing his job, he recaptured all escapees. His interactions feature unreciprocated affection, like his hospital visits or interest in Genos during meetings. He openly challenged Sweet Mask’s condescending attitude toward S-Class heroes and later considered a master/slave dynamic with him. He motivated Superalloy Darkshine during the raid by threatening a "deep kiss," prompting Darkshine to rejoin the fight.
