The landscape of modern anime is rich with series that balance explosive action with deep introspection, but few creators manage to weave comedy into that tapestry as deftly as ONE. Through One Punch Man and Mob Psycho 100, he has crafted two narratives that, on the surface, appear to be simple parodies of the superhero and psychic genres. A closer look reveals that humor is not just a seasoning—it is the engine driving profound explorations of power, identity, and the human condition. Both series follow protagonists who are impossibly strong yet emotionally complex, using laughter to disarm the audience before delivering surprisingly poignant truths.

Foundations of Comedy and Heroism: An Overview of One Punch Man

One Punch Man began as a webcomic before exploding into a global phenomenon through its manga adaptation illustrated by Yusuke Murata and subsequent anime production by Madhouse (season one) and J.C.Staff (season two). The story revolves around Saitama, a hero who has trained so rigorously—albeit with a mundane routine of 100 push-ups, 100 sit-ups, 100 squats, and a 10-kilometer run every day—that he has lost all his hair and gained the ability to obliterate any opponent with a single punch. This absurd premise immediately sets the stage for a comedy that lampoons the very structure of shōnen battle anime.

The humor in One Punch Man often derives from a technique best described as anticlimax delivered with utmost sincerity. Saitama’s deadpan expression and prosaic concerns—like missing a supermarket sale—clash with the apocalyptic monologues of his foes. The series is a masterclass in juxtaposition: monstrous beings deliver Shakespearean threats while Saitama wonders if he left the stove on. This contrast is not only funny but functions as a critical observation on the inflation of stakes in action storytelling. Where other heroes train for years to overcome a single enemy, Saitama’s struggle is purely internal. His battle isn't with the villain of the week; it's with ennui.

Subverting the Superhero Mythos

The Hero Association ranking system, which places Saitama inexplicably low despite his power, becomes a fertile ground for satire. The series targets bureaucratic incompetence, the cult of celebrity, and the superficial metrics by which society often measures worth. The humor arises from Saitama’s obliviousness to fame and his genuine desire for recognition, which is constantly thwarted. This disconnect is explored through the eyes of the cyborg Genos, Saitama’s self-appointed disciple, who takes everything—training, threats, declarations of vengeance—with extreme seriousness. Their odd-couple dynamic is the comedic heart of the series, turning mundane moments like hotpot dinners into hilarious studies of personality contrast.

In fact, Genos's character grants the series a secondary layer of meta-humor through his tendency to deliver lengthy, detailed backstories about his tragic past while Saitama begs him to shorten it to twenty words or less. This not only generates laughs but works as a critique of exposition-heavy anime. The series consistently winks at its audience, acknowledging the tropes and then gleefully smashing them aside.

The Emotional Spectrum: A Look at Mob Psycho 100

If One Punch Man is a deadpan farce, Mob Psycho 100 is a vibrant, heartfelt comedy-drama that wears its emotions on its sleeve. The anime, produced by the legendary studio Bones, follows Shigeo "Mob" Kageyama, a middle school student brimming with unfathomable psychic energy. The twist is that his power is tied to his emotional state: an internal counter ticks toward 100 as he absorbs negative feelings, and when it reaches that threshold, an explosive, often terrifying release occurs. The overarching goal for Mob is not to increase his power but to control it, while also learning to navigate the ordinary challenges of adolescence.

The humor here is gentler and more character-driven, rooted in the awkwardness of growing up. Mob’s near-total lack of charisma, his blunt observations, and his earnest attempts to improve himself physically despite having no need for muscles create a sympathetic kind of comedy. Unlike Saitama, who is largely at peace with his condition (except for the lack of recognition), Mob is a ball of repressed anxiety. The gags—such as Mob desperately trying to impress a girl by joining the Body Improvement Club, only to discover that his spiritual powers can’t help him lift a barbell—succeed because they highlight a universal vulnerability: the fear of not being good enough.

The Con-Man and the Protégé

Central to the series’ humor is Reigen Arataka, Mob’s mentor. Reigen is a charismatic fraud who runs a psychic consultation business despite having no powers himself. He relies entirely on Mob for genuine exorcisms, yet constantly positions himself as the master. The irony is that Reigen's cynical, street-smart advice often contains more practical wisdom for Mob than any psychic training could. Their relationship provides a continuous stream of situational irony and visual gags—Reigen flexing powers that do not exist while Mob, deadpan but unnerved, powers up behind him. Yet Reigen is never merely a joke. His passionate defense of Mob and his unexpectedly profound speeches about the value of a well-rounded life form the story’s philosophical backbone.

Secondary characters like the cult leader Dimple (a fart-shaped ghost with delusions of grandeur) and Mob’s younger, attention-seeking brother Ritsu add further comedic friction. Ritsu’s jealous admiration and eventual descent into a power trip, contrasted with his usual perfect-student facade, uses humor to explore sibling dynamics and self-worth. The series layers multiple comedic registers: physical comedy via Dimple’s malleable form, dry wit via Mob’s inner monologue, and slapstick via Reigen’s flamboyant cons.

Comparative Thematic Architecture: Power as Paradox

Placing these two series side-by-side reveals how ONE uses comedy to examine the nature of power from opposing angles. In One Punch Man, power is a settled question from episode one. The comedic tension comes from watching everyone else—heroes, villains, civilians—struggle with a reality they cannot comprehend. Saitama’s strength is a satire of the shōnen escalation curve: he has already finished the journey, so what remains? The answer is an exploration of existential boredom. When a mosquito keeps dodging Saitama’s swats, it’s a hilarious inversion of his invincibility; his greatest foe is a common insect, underlining the absurdist message that ultimate power does not equate to a fulfilling life.

In Mob Psycho 100, however, power is ever-present but intentionally suppressed. The humor emerges from Mob’s desperate attempt to define himself by anything other than his ability. He envies his body-building club mates because their achievements are earned through effort, not given. The series uses comedy to soften the terrifying reality that Mob could accidentally annihilate his city if he gets too emotional. A schoolyard crush, a failed exam, or a mean comment from a classmate becomes a ticking time bomb, blending slice-of-life awkwardness with a persistent undercurrent of dread. The emotional percentage counter itself is a brilliant comedic device that visualizes internal turmoil, turning every social stumble into a dramatic countdown.

Where Saitama’s journey is about finding meaning after the summit is reached, Mob’s journey is about learning that the summit is irrelevant. Power, for both, is a burden that isolates them, but the tone of that isolation differs drastically: satirical despair versus adolescent anxiety, respectively.

The Role of Identity and Self-Acceptance

Humor serves as the primary vehicle for identity exploration in both narratives. Saitama’s identity crisis is rendered comically through his chronic underappreciation. Despite being the most powerful being in his universe, the public knows him as a fraud, a cheat, or simply ignores him. His internal monologues about the emptiness of a hero’s life, delivered while he lazily watches TV or swats a monster, encapsulate a midlife crisis wrapped in a superhero cape. The humor here is deeply philosophical: what is a hero without the struggle? The series pushes this further by having Saitama impersonate a criminal to enter a martial arts tournament, leading to a series of deadpan lies that completely fail to fool anyone, highlighting that his true identity is fundamentally incompatible with the world’s expectations.

Mob’s identity work, by contrast, is about accepting his emotions as part of his strength. The comedy often comes from his literal-minded interpretation of advice. Told that he needs to be more outgoing, Mob attempts to smile, resulting in a terrifying, dead-eyed rictus that frightens people more than any psychic blast. The Body Improvement Club serves as a beautifully ironic safe haven; the club members, all muscular and supportive, never mock Mob’s lack of physical ability and eventually become some of his truest friends. This group normalizes his quest for a multidimensional self, showing that even in a world of psychics, the high-five after a successful bench press can carry as much narrative weight as a telekinetic battle.

Social Commentary Through Satire

Both series deploy humor as social criticism, though their targets differ. One Punch Man relentlessly lampoons institutional apathy and media-driven heroism. The Hero Association is a paradise of red tape where threats are categorized by arbitrary danger levels, and public relations often outweigh actual heroism. The character of King, a normal man who accidentally receives credit for Saitama’s deeds, is a walking joke about image versus reality. The series asks whether society values the hero or merely the spectacle of heroism, a question delivered with laugh-out-loud cynicism as King’s heart pounds audibly in terror while heroes around him interpret it as his “battle aura.”

In Mob Psycho 100, the social critique is more intimate, targeting the pressures of conformity and the damage caused by unchecked authority. The antagonist Claw organization, composed of adult psychics who believe in world domination, is essentially a group of emotionally stunted individuals who never outgrew their childhood fantasies of superiority. Their plan is exposed as pathetic and immature through Mob’s blunt rejection, draining the drama of its menace and filling it with a kind of empathetic humor. The message is clear: those who cling to power as a substitute for personality are to be pitied, not feared. The show’s treatment of cults, pyramid schemes, and self-help scams (via Reigen) gently mocks the human tendency to seek external validation rather than do the hard inner work.

Aesthetic and Narrative Dissonance as Humor

The visual language of both anime adaptations amplifies their distinct comedic voices. One Punch Man, especially in its first season, is famous for its high-budget, cinematic sakuga sequences that depict Saitama’s opponents in immaculate, fluid detail—only for Saitama himself to be rendered in a simplistic, almost doughy style. This visual gap itself is a joke: the narrative’s ultimate power looks the least impressive. The contrast between Genos’s high-tech, incinerator-cannon arm and Saitama’s “consecutive normal punches” delivers physical comedy that underscores the thematic disparity between effort and ability.

Mob Psycho 100, courtesy of director Yuzuru Tachikawa and character designer Yoshimichi Kameda, employs a wildly expressive, almost unhinged animation style that freely morphs between crayon-textured surrealism and hyper-detailed psychic warfare. When Mob’s emotional counter hits 100, the visual world fractures; paint splatters, chalky outlines, and distorted proportions visually communicate the overwhelming nature of repressed feelings. The humor benefits from this elastic reality: Reigen’s signature move, the “Self-Defense Rush,” is a flurry of meaningless punches that the animation sells with power-shaking intensity, only to reveal his complete ineffectiveness. This visual hyperbole mirrors the show's belief that emotion, not physical reality, is the truest experience.

Supporting Casts as Comedic Mirrors

No discussion of humor in either series is complete without acknowledging the ensemble casts that contextualize the leads. In One Punch Man, heroes like Mumen Rider, the C-class cyclist who never gives up despite having no special power, provide a kind of sincere counterpoint that makes Saitama’s apathy funnier by contrast. Mumen’s tearful, futile charges against unbeatable enemies are played straight, which paradoxically makes them hilarious and deeply moving. The series suggests that genuine heroism might look like Mumen, while ultimate power looks like Saitama—and neither is fully satisfied.

Mob Psycho 100 uses the Telepathy Club and various school rivals to amplify Mob’s social discomfort. Tome Kurata, the Telepathy Club president obsessed with aliens, drags Mob into absurd adventures that always end in proof that humans are stranger than any extraterrestrial. The humor is rooted in the mundane: these psychics use their abilities to find lost cats or cheat at arcade games, not to battle cosmic threats. This grounding makes the rare moments when Mob unleashes his full power all the more staggering, while ensuring that the story’s heart remains firmly in the everyday struggles of connection and acceptance.

Cultural Impact and Fan Reception

The global embrace of both series attests to the universality of humor as a gateway to theme. One Punch Man became an instant sensation in 2015, with discussions across platforms like MyAnimeList centering not just on the animation quality but on how its comedy revolutionized the superhero parody. Memes of Saitama’s ok face and his “I’m just a hero for fun” line proliferated, embedding the series in internet culture. Mob Psycho 100, while often living in the shadow of its older sibling’s popularity, has cultivated a dedicated fanbase that praises its emotional depth. Review aggregators like Crunchyroll highlight the show’s balance of psychic spectacle and earnest storytelling, frequently citing Reigen as one of anime’s greatest comic mentors.

Critics have noted that ONE’s works represent a shift in shōnen storytelling—away from power escalation and toward personhood. A 2022 feature on Anime News Network argued that Mob Psycho 100 redefined the coming-of-age genre by insisting that true strength is vulnerability. Similarly, academic discussions on popular culture have pointed to Saitama as a symbol of post-growth stagnation, a hero whose dilemma resonates in a world tired of relentless self-optimization. These interpretations are possible precisely because the humor invites viewers to let their guard down and engage with discomfort.

Bridging Genres: When Comedy Becomes Existential

Ultimately, the most striking shared achievement of One Punch Man and Mob Psycho 100 is their ability to make audiences laugh until they realize they are weeping. Saitama’s crowning moment in season one—defeating the world-ending Lord Boros while acknowledging that the alien’s search for a worthy foe mirrors his own—is simultaneously thrilling, absurd, and tragic. Boros, a being who conquered galaxies, is reduced to a final disappointment, recognizing that the prophecy he chased was as empty as Saitama’s daily life. The comedy of Saitama holding back, concerned more about Boros’s feelings than the battle, lands as a profound reflection on shared loneliness.

Mob’s journey leads to a similar convergence. In the climactic arcs of season two and three, his refusal to use powers against those who have hurt him becomes a radical act of self-definition. The humor of Reigen’s frantic cover-ups and Dimple’s ghostly schemes fades into a quiet, powerful assertion: Mob is not his power, he is his choices. As chronicled on platforms like Comic Book Resources, the series redefines strength as empathy, a message that lands so effectively because the comedic tone prevents it from feeling preachy.

Both series stand as landmark examples of how anime can use humor to transcend genre boundaries, creating stories that are as intellectually stimulating as they are entertaining. Whether through Saitama’s existential yawn or Mob’s anxious emotional counter, ONE reminds us that the greatest battles are fought within, and that laughter is perhaps the most honest way to face them.
