Puri-Puri Prisoner/Synopsis

Sea Monster Arc
Puri-puri Prisoner arrives to catch the unconscious form of Lightning Max after Max's defeat at the hands of Deep Sea King. After a short conversation with Sonic, Prisoner examines the battlefield and upon realizing that both Stinger and Lightning Max, two heroes who he had taken an interest in, were defeated by the Deep Sea King he states that he will never forgive him and proceeds to power up to half strength, destroying his sweater in the process. Devastated by the destruction of his sweater, a consequence he apparently blames on the Deep Sea King, Prisoner becomes even more enraged. He is then hit with a heavy blow from the monster, but the attack apparently had little to no effect as Puri-puri Prisoner quickly retaliates with a blow of his own.

After unleashing a destructive flurry of punches upon a surprised Deep Sea King, Puri-puri Prisoner remarks that he barely felt Sea King's punch, although Sonic notices that Prisoner is having trouble keeping his balance and Puri-puri Prisoner himself states internally that the blow was way more powerful than he expected.Determined not to lose, Prisoner resolves that his only choice is to transform and proceeds to transform into Angel ☆ Style.

Powered up, Prisoner states that nobody has ever seen him in Angel ☆ Style and lived to tell about it. He then unleashes his special attack Angel ☆ Rush upon the Deep Sea King. After realizing that his attack had no effect on Deep Sea King, Puri-puri Prisoner is assaulted by the monster's vicious blows and, with one final kick, is effectively blown away from the fight.

Puri-puri Prisoner visits both Stinger and Lightning Max in the hospital after breaking out of jail again and tries to give them what he called Angel Shots, but they quickly run off in fear. He is calling for them to come back to take their medication, as a newspaper falls next to his feet and looks, only to find the page showing him with the title S-Class failure that left Puri-puri Prisoner depressed.

Alien Conquerors Arc
Puri-puri Prisoner is seen at the S-Class Hero Association meeting and whilst sitting there privately hopes he can use the opportunity to get closer to Genos. During the meeting, he was asked by Saitama, about the Shibabawa, to which Puri-puri Prisoner explains. After the destruction of A-City, he took part in the group fight against Melzargard with Atomic Samurai, Bang and Metal Bat. During the fight, Puri-puri Prisoner demonstrated a new technique inspired by the Deep Sea King's word, naming it Dark ☆ Angel ☆ Rush. The S-Class heroes were struggling to defeat Melzargard, until Metal Bat found its weakness. After the heroes defeat Melzargard, the spaceship began crashing down and the S-Class heroes run to safety. After the invasion was over Puri-puri Prisoner and the other S-Class heroes were patronized by Sweet Mask to which Puri-puri Prisoner questions Sweet Mask's attitude.

Super Fight Arc
He is briefly mentioned by the Nyan who invaded Smelly Lid Prison to look for him, only to discover he is not there.

He later encounters Free Hugger and, despite taking injuries, manages to defeat the monster after using Angel ☆ Hug instead of using the iron ball chained to his leg. He then received a call that the prisoners of Smelly Lid Prison have been kidnapped.

He is sent by the cops to kill Nyan.

Original Webcomic
He accompanies the other S-Class heroes against the Monster Association. Later in the fight against Garou, he is assigned the task to find Darky (Puri-puri Prisoner's nickname for Superalloy Darkshine) after he lost his confidence and went into hiding. He eventually finds him, but is unable to get him back on his feet because he is still distraught. To prove he is worthy, Puri-puri Prisoner lets out a full power punch on Darky to prove that he is strong enough. It left him unscathed and after a little bit more of talking, he gets Darky to get back on his feet and fight. They join Flashy-Flash and Saitama (who was not given the chance to fight until a little later) in the fight against Garou. Unfortunately, they weren't enough (not including Saitama) to beat the newly transformed Garou, even with the combined strength of all 3 S-Class heroes.
