In Episode 2 of One Punch Man, titled "The Lone Cyborg," the story continues as Saitama meets a powerful new character, Genos, who will become his first disciple and a significant ally.
The episode begins with a giant mosquito swarm attacking a city. These mosquitoes are led by a fearsome villain known as Mosquito Girl, a humanoid insect who feeds on the blood of humans and animals. As her swarm drains blood from the victims, she grows stronger and more dangerous.
At the same time, we are introduced to Genos, a 19-year-old cyborg hero with a tragic past. Genos is on a mission of vengeance, seeking to destroy the rogue cyborg that killed his family and left him mortally wounded, leading to his transformation into a cyborg. Genos, equipped with powerful weaponry and combat abilities, engages in a fierce battle with Mosquito Girl and her swarm.
Despite his strength, Genos struggles against Mosquito Girl, who continues to grow stronger as her swarm gathers more blood. The fight seems evenly matched until Saitama arrives on the scene, clad in his usual plain clothes. At first, Saitama is annoyed by the mosquitoes, which he finds irritating as they swarm around him. When he tries to swat a single mosquito and fails, he becomes increasingly frustrated.
As the battle between Genos and Mosquito Girl intensifies, Saitama casually approaches them, seemingly uninterested in the fight. Mosquito Girl, now at her peak strength, mocks Genos and prepares to finish him off. However, Saitama, with his usual nonchalance, delivers a single, devastating slap to Mosquito Girl, obliterating her instantly. The once-dangerous villain is reduced to nothing, leaving Genos in awe of Saitama's incredible power.
After the battle, Genos approaches Saitama and requests to become his disciple. Genos is deeply impressed by Saitama's strength and wants to learn how to become as powerful as him. Saitama, who initially finds Genos’s request bothersome, eventually agrees to let him follow him around.
The episode also provides a glimpse into Genos’s backstory, revealing the trauma and drive that fuels his quest for vengeance. Despite his serious demeanor, Genos’s interactions with Saitama bring a comedic element to the story, as Saitama’s laid-back attitude contrasts sharply with Genos’s intense, focused nature.
The episode ends with Genos moving in with Saitama, marking the beginning of their partnership. While Saitama is still searching for excitement and meaning in his life as a hero, Genos’s determination to learn from him hints at the start of a new dynamic that will shape their adventures together.
