Neo Heroes Uprising Arc

The New Heroes Showcase Arc is the twentieth arc of the One-Punch Man series, and the fifth arc of the Neo Heroes Saga.

Plot
In the Hero Association headquarters, three heroes are considering joining the Neo Heroes after being scouted. They discuss the benefits of the Neo Heroes compared to the benefits of the Hero Association, and come to the conclusion that the Neo Heroes would be much better for them personally. Rover and Black Sperm are present, and Black Sperm thinks about the current situation, that two rival Hero associations are combatting instead of focusing on working together to fight monsters. He remarks that the current situation will be beneficial for the two monsters, with the effectiveness of heroes slowly declining. Saitama approaches the three heroes and is asked if he has been scouted by the Neo Heroes. Suddenly, a group of heroes discontent with their hero names approaches Saitama and asks to have him as a leader because of his unfortunate hero name. Black Sperm continues to ponder, using the newly arrived group as proof that the Hero system is close to failing.

Suiko arrives at the Hero Association headquarters and is welcomed in. While being led to the training grounds, she is told that her brother, Suiryu, won the Super Fight tournament and that the Hero Association wants him as a hero as well. Suiko says that that isn't necessary, and that she is stronger than Suiryu. In the training grounds, Suiko demonstrates her strength by easily destroying a training robot. She is disappointed that this feat landed her in A-Class and not S-Class.

At the Neo Heroes headquarters, Suiryu is being escorted by McCoy. He seems to not take what McCoy is saying very seriously about what he should do as a hero, instead he simply understands that he needs to defeat monsters and he will get paid. Outside of the headquarters, Genos and Saitama spar in order for Genos to collect battle data from the fight. Genos questions to himself what happened between Saitama and Sweet Mask after the two left the amusement park. Genos remarks that the look on Saitama's face is different from the usual. It turns out that Saitama was just thinking about the Hero Name Victims Association.

Later, Suiryu is introduced to the Neo Leaders and McCoy tells them that Suiryu will be a leader. Next, each of the Neo Leaders are similarly introduced. Raiden is introduced as an impressively strong sumo champion who is claimed to even surpass the S-Class. Raiden notes that Darkshine is quite well known and asks to compare the two's strength. The lock hands and Darkshine seems to be slightly overwhelmed by Raiden's strength. After the bout, Raiden believes that Darkshine might be past his prime. Suddenly, two Leader candidates barge in, angry that they were not accepted to be leaders. Mars Leo shows off his speed and lets one of his punches hit Darkshine, breaking his own wrist. Suiryu buts in between the two, and is attacked by both of the candidates, effortlessly fending off their attacks. McCoy continues with introductions, and the two leader candidates are ushered away by Erimin and Destro. McCoy concludes by introducing Blue, who had just arrived. He explains that Blue is the reason the Neo Heroes exist.

Then, a flashback shows how Blue chased Saitama and Sweet Mask. In order to keep up with the two, he removed the limiter on his suit and likely began speeding up. Before long he is stopped by Genos who asks what he is doing. Blue asks if this is the Hero Association's attempt to protect Sweet Mask and also questions Saitama's speed. Blue implies a threat, and wants answers from Genos. Genos says that he doesn't know what Saitama will do with Sweet Mask. Back in the present, Blue explains why he created the Neo Heroes, before being revealed as Blast's son.

Great Philosopher is ready to engage with monster Sewage Crocodile. He defeats it with relative ease before being swarmed by several of the same monster. After some time he is saved by a group of Neo Heroes, and group talks about how easy the fight was before being confronted by a large monster. They call on Webigaza, who defeats it, recording the battle for her fans to see. In another area, Raiden is dispatching a swarm of monsters, saving a Hero Association hero. He criticizes the battle suits given to the Neo Heroes members. The news reports on a large number of high level monsters, and notes that they are all being soundly defeated by the Neo Heroes. Accel is also present, and with the help of the Hunters defeats Explosive Velocity Snail, a Demon-level threat. Crescent Eyebroll is also dealing with the monsters, but is being overwhelmed by Triple Tongues. Ryumon interrupts and engages the threat. Child Emperor wonders about the battle suits given to the Neo Heroes, and questions if they are created by Bofoi and given to the Neo Heroes.He wonders if he will have to do something about this.

A and Suiryu are also seen dispatching monsters successfully. Zaedats attempts to combat Demon-level threat Meat Dumpling, but is soundly defeated by the monster despite the use of his equipment. Infelsinave is also seen having been defeated by a monster. Metal Bat praises the power of the suits, easily dealing with the threats. Blue is also in action, confronting Shell King. He destroys the monster with little effort, though still realizes that Demon-level threats are quite troublesome. After killing the monster, the Shellfolk become angered and attempt to attack Blue, though he quickly deals with them. Blue talks to McCoy, telling him to warn the other Neo Heroes to not get cocky just because they have a battle suit. Blue then leaves to continue battle.

The Hero Association discusses the situation, saying that they need stronger leaders and soon they will start losing supporters. Suddenly, the Hero Name Victims Association shows and begins making requests. This makes Sitch think that they are already done for. An announcement is made outside the headquarters that five Dragon-level monsters have been spotted. Headquarters is put into lockdown and Genos, Tanktop Master, and Tatsumaki have been dispatched. Sitch urges to ask the Neo Heroes for help.

Tanktop Master engages Heavy Smoker. He uses a special tanktop, one that raises power at the expense that it can only be used for a short time. Tatsumaki handles the monster Aggregation, not having much difficulty but is disgusted at its appearance. Genos engages The Extended Family of Darkness and prepares to use a new move. In L-City, Blue is busy battling Eel Dragon. Mirror, a robot created by The Organization, attacks Y-City and wants to find King. Suiko confronts and prepares to attack the threat.
