Puri-Puri Prisoner is a large muscular man with a stubbly, cleft chin, large lips, and black bushy hair. He has a well-defined jawline and light blue eyes with long eyelashes. He wears a traditional prison jumpsuit with white and blue stripes. He used to wear a white sleeveless vest with a large pink heart in the center over his prison clothes, but he ripped it during one of his transformations.
Puri-Puri Prisoner is a flamboyant, openly homosexual superhero. He takes an interest in other good looking male heroes and criminals; an interest which led to his titular jail sentence, as he kept attacking them. Criminals that he apprehends are then added to his harem. He appears to be rather absent-minded, as he did not think to remove his sweater before bulking up, and then blamed his opponent, the Deep Sea King, for its destruction.
Outside his homosexuality, he also has a standard about a true justice, on protesting Sweet Mask's attitude on criticizing and mocking the hardships of the S-Class and A-Class heroes on trying to risk their lives protecting A-City, and resisting an unexpected invasion from the Dark Matter Thieves, asking Sweet Mask on which side he truly is.
He also seems to take pride in his position, as part of the reason he wanted to defeat the Deep Sea King was because Genos had surpassed him in rank and he wanted to prove his worth as a S-Class hero.
As the lowest ranked hero in S-Class, he seems to be more down to earth and genuinely heroic than some of the more self-absorbed heroes in S-Class. Though he escaped prison to fight the Deep Sea King under the pretense that he had done it to prove his worth after being outranked by Genos, his internal dialogue at the time also indicated that he did it because he didn't want to see any more Heroes get hurt. He also seems relatively kind and very polite, demonstrated when he took the time to inform Saitama about the late seer Shibabawa during an S-Class hero meeting about the prophecy, whereas many of the other S-Class heroes automatically dismiss Saitama as not worthy to speak to them, due to his lower rank. He also showed humility and maturity following his defeat by the Deep Sea King, not being above taking the creature's advice about combos to heart in order to develop a new technique. Later, when Sweet Mask berates the S-Class heroes for A-City's destruction, Puri-Puri Prisoner refrained being argumentative and instead tried to defuse the situation, showing that despite his flamboyant antics, he is capable of demonstrating calm, reason and tact in serious situations.
Abilities and Powers
Being a S-Class hero, Puri-Puri Prisoner is a very powerful individual. He is able to blow holes in the body of a Dragon-level monster and deal minor damage to the Deep Sea King while not having killling intent. However, while powerful, he self-proclaims himself to be the weakest S-Class hero. This is shown at the beginning of the series when he had difficutly fighting some Demon-level mysterious beings. However, after his training, his power greatly increased to the point of being able to defeat several Demon-level mysterious beings, although he's often required to use his special moves to defeat them, while other S-class heroes have been able to defeat Demon-level mysterious beings with ease.
Immense Strength: Puri-Puri Prisoner possesses immense physical strength, as seen when he easily breaks through the thick steel walls of the Smelly Lid Prison, which prompted Speed-o'-Sound Sonic to remark that he was even stronger than Hammerhead was in the battle suit, although this was without him seeing Hammerhead use the full power of the battle suit against Saitama.
