One Punch Man fans are excited about the announcement of season 3 airing in 2025, and they are also curious about the new characters that will appear in the Monster Association arc.
The Monster Association arc will likely be split into two parts due to the complexity of the story in the lair controlled by Gyoro Gyoro and Monster King Orochi.
Excitement surrounds fans who are waiting for a new debut in the anime’s third season. For those who haven’t read the manga, there are a few possible candidates. However, readers should keep in mind that the order of events may change in the adaptation from manga to anime.
List of Characters that May Appear in One Punch Man Season 3
1. Blast

One-Punch Man fans are eagerly awaiting the Monster Association Arc, which will introduce Blast, the Nº1 S Rank Hero and said to be the most powerful. Although Blast has appeared in teaser form in seasons 1 and 2, he has yet to make a live appearance.
This time, Blast will join other heroes to dive into the Monster Association’s Lair and meet Saitama. He reveals that his task is to track down a mysterious interdimensional being called Dewa, who has long been his enemy and is thought to be related to the appearance of Monsters on Earth.
His presence will set the scene for the events fans have been waiting for, namely the explanation of the origin of Saitama’s extraordinary powers.
2. Captain Mizuki

The Heroes’ Association is recruiting a team to raid the monster lair in Z City. Captain Mizuki, a former star athlete, is one of the B Rank Candidates who desires to be promoted to A Rank. He sees this mission as an opportunity to increase his rank within the Hero Association.
Mizuki unknowingly gets involved in a dangerous mission against powerful creatures from the Monster Association. He is determined not to let his shortcomings burden others. The character is a fan favorite of the One Punch Man manga, and it is hoped that her popularity will increase even more when she debuts in the anime.
3. Overgrown Rover

The next fan-favorite character that may appear in One-Punch Man season 3 is Overgrown Rover, a Dragon-level monster in the form of a giant dog with many eyes. It was created from an abandoned dog left behind during the evacuation of Z-City and now guards its former home with great viciousness.
In the Monster Association Arc, Saitama tamed a monster by giving it a bone, which then turned into a small but powerful creature. Rover was eventually discovered by Genos and Saitama, and is now a permanent member of the team with Black Sperm.
4. Homeless Emperor

The strongest member of the Monster Association, he is a being who gained extraordinary powers after being touched by ‘God’. With a messiah complex, he believes humans are a plague and he is the chosen one to destroy them to save the planet.
The Homeless Emperor has the ability to create and control energy, and can create sentient missiles that track enemies. His strength, speed and endurance are on par with superhumans.
The Homeless Emperor is a powerful Dragon-level being, perhaps even more powerful than Orochi and Gyoro Gyoro (Psykos). Despite this, he chose to support them in conquering humanity for the sake of the beings who would inherit the world.
Previously, he was an office worker who was fired, bullied, and kicked out until he became homeless. His encounter with a mysterious creature called ‘Dewa’ turned him into a threat to anyone who stood in his way.
5. Platinum Sperm

Black Sperm, in its peak form, is a monstrous monster made up of thousands of billions of perfectly fused cells. Recalling the character Cell from Dragon Ball Z, it possesses incredible strength as well as speed. Platinum Sperm represents ultimate arrogance and power, and is one of the strongest fighters in the Monster Association.
This monster can fight the strongest S-Rank heroes like Atomic Samurai and Genos. Atomic Samurai struggles because this monster is a very strong opponent. Although he can cut through enemies at a sub-atomic level, Platinum Sperm’s regeneration is faster, making it difficult for him to defeat this Dragon Level monster.
6. Psykos

Psykos, an Esper who was piloted and trained alongside Tatsumaki and Fubuki, is the brains behind the Monster Association’s operations. He became an enemy of the Tornado of Terror and is obsessed with killing Tatsumaki and proving his power as an Esper and his prowess as a strategist.
With great mind manipulation abilities, he utilizes Gyoro-Gyoro as a medium to communicate with Lord Orochi. It is likely that he will appear in the anime as one of the main antagonists facing the heroes in the upcoming arc.
7. God

Mysterious inter-dimensional beings allegedly gave powers to certain monsters and heroes. A prolonged battle with Blast, the strongest hero on Earth, caused the Association to be absent for many years. The fight between Blast and this creature took place in unknown territory, creating a dangerous conflict.
Strong antagonists emerge as Garou transforms into a monster and Saitama’s mysterious powers. Fans better wait to uncover these secrets when One Punch Man Season 3 is released on streaming services.
Those are some characters from the One Punch Man series that are likely to appear in season 3 if it is true that it will adapt the Monster Association arc. Are you also looking forward to the new season? Stay tuned for news updates about One Punch Man on Dafunda.
