Every time I brought up One Punch Man in any anime conversation, someone said the same thing: “It’s good, but have you watched Mob Psycho 100? That’s the one that’s actually great.”
I heard that probably five times before I did anything about it. My reaction was always some version of: “Sure. I’ll get to it.” Which is what I say when I’m not convinced but don’t want to argue.
I was wrong to be skeptical. I want to lead with that.
Mob Psycho 100 is the better show. I didn’t want to believe it because I liked OPM a lot and I didn’t think the comparison was fair — same creator, completely different premise, different tone, different emotional register. But after finishing Season 3 I understood what everyone was trying to tell me. One Punch Man is a show about what happens after you win. Mob Psycho 100 is about what you do with the power you have before you waste it. Season 3 is where that thesis fully pays off. It hit me in a way OPM never did.
Here’s the watch order and why it’s worth your time.
The Watch Order (Simple Version)
This one is easy. There’s no complicated movie placement, no mandatory side content, no special order that changes how the ending lands.
- Mob Psycho 100 Season 1 (2016, 12 episodes)
- Mob Psycho 100 II Reigen: The Miraculous Unknown Psychic (2019, 1 episode OVA — optional, funny, short)
- Mob Psycho 100 Season 2 (2019, 13 episodes)
- Mob Psycho 100 Season 3 (2022, 13 episodes)
That’s it. Start at Season 1 and go straight through. There are a handful of other small bonus episodes and recap content floating around on streaming platforms, but nothing there is required. The Reigen OVA is the only extra worth calling out specifically because it’s genuinely entertaining — it’s a Reigen-focused comedy episode that doesn’t advance anything plot-wise but spends about 20 minutes reminding you why Reigen is one of the best side characters in anime. Watch it if you want a breather between Season 1 and Season 2.
Everything else, skip it. The four entries above are the actual show.
What Mob Psycho 100 Is
The short version: Shigeo Kageyama — called “Mob” as in a background character, someone who blends in — is a middle schooler with psychic powers so overwhelming they scare him. He’s suppressing them constantly. He works for a fake psychic named Reigen Arataka, who runs a con-man exorcism business and genuinely has no powers himself, but who somehow ends up being the most important adult figure in Mob’s life.
That’s the setup. But here’s the thing that separates it from a typical “overpowered kid” story: Mob is not trying to be powerful. He doesn’t want to fight. He’s trying to figure out who he is as a person — separate from his abilities — and the show takes that question completely seriously. Every arc is some version of: what does it mean to be a person, and how do you decide what to do with what you’ve been given?
It’s also extremely funny. Reigen is a masterclass in con-man-with-a-heart writing. The show never becomes grim or self-serious. It manages to be genuinely moving and genuinely funny in the same episode, sometimes in the same scene, in ways I wasn’t expecting.
Season 1: The Foundation
Season 1 is where the world gets built and where Mob’s central situation gets established. It’s also where Bones — the animation studio handling the show — makes it clear they’re doing something unusual visually. The art style is deliberately rough and simple on the surface, but the action sequences open up into something that looks unlike anything else in anime. There are sequences in Season 1 that use psychedelic color and fluid motion in ways I hadn’t seen before, and they work because the base style is restrained enough that when the show decides to explode visually, you actually feel it.
The season introduces the central conflict that runs through all three seasons: Mob is suppressing his emotions because when they hit 100%, the powers release in ways he can’t control. It’s not played as a threat exactly — more as a portrait of a kid who’s terrified of what he might do and has decided the answer is to feel less. That’s the problem the show spends three seasons solving.
Watch all 12 episodes. The finale alone is worth the runtime.
The Reigen OVA
One episode. It’s from Reigen’s perspective, structured as a comedy about his life as a professional fake psychic who accidentally became famous for the wrong reasons. Watch it between Season 1 and Season 2 as a palate cleanser. It doesn’t change anything about the main story but it’s well done and if you like Reigen — which you will — it’s an easy yes.
If you’re in a hurry to get to Season 2, skip it. You won’t miss any plot.
Season 2: Things Get Complicated
Season 2 deepens everything Season 1 built. The stakes get bigger, the emotional arcs get more specific, and the show starts doing something I really wasn’t expecting: it complicates Mob’s relationship with his own power in a way that goes beyond the Season 1 setup.
The organization called Claw, the psychic underground, Mob’s brother — Season 2 expands the world significantly. But the thing I’ll remember most about Season 2 is a late-season sequence that I won’t spoil that manages to be one of the most unexpected action scenes in the whole show and also, somehow, an emotionally devastating statement about identity and self-worth. Bones does something with the animation in that stretch that I’ve rewatched multiple times.
Season 2 is excellent. If Season 1 was the setup, Season 2 is the show finding its full voice.
Season 3: Where It All Clicks
I want to be specific about this because it’s the thing nobody told me clearly when people said Mob Psycho was the better show.
Season 3 is where everything pays off.
One Punch Man is about someone who has already arrived — Saitama achieved his goal and found nothing there. The show is an extended meditation on that emptiness. That’s a real theme and the show handles it with more intelligence than the premise suggests. But it’s also a premise with a ceiling. Saitama can’t really grow because growth is the thing the show is arguing is hollow.
Mob is different. Mob has power and is still deciding what kind of person to be. He’s not post-growth. He’s in the middle of it. And Season 3 is where all three seasons of character work — the suppression, the relationships, what Reigen actually gave him, what his brother actually needed, what strength actually means to him — come together in a finale that earned real emotion from me.
I don’t get emotional watching anime that often. Vinland Saga got me. Mob Psycho 100 Season 3 got me. I was not expecting that going in.
That’s the thing people were trying to tell me when they said it was the better show. Not that OPM is bad — OPM is genuinely great. But Mob Psycho 100 is genuinely moving in places OPM never is, and Season 3 is why.
OPM vs. Mob: The Honest Comparison
Both shows are by ONE. Both are technically about overpowered protagonists. Both are produced with serious animation craft — OPM Season 1 by Madhouse, Mob Psycho by Bones throughout, consistently high quality.
But they’re not the same project.
One Punch Man is fundamentally a comedy about the absurdity of peak achievement and what comes after. The emotional core is philosophical: what’s the point of strength if nothing challenges it? Saitama is interesting as a concept. He’s not really a character who changes.
Mob is a character who changes. That’s the whole show. He starts it afraid of himself and ends it as a person who understands what his power is for and what it isn’t for. That arc spans three seasons and it’s constructed carefully enough that the payoff at the end actually lands.
My verdict: Mob Psycho 100 is the better show. It’s funnier than I expected, more emotionally substantial than I was prepared for, and the visual craft from Bones is exceptional all the way through. I still love OPM. I’ll rewatch OPM Season 1 happily. But if you’re asking me which one I think about more — which one actually did something to me — it’s Mob.
The Tanner Question
Tanner is six, so the answer for him right now is still no. Mob Psycho has intense action sequences, some legitimately scary psychic imagery, and enough emotional weight that it’s best watched by someone who can actually follow what’s happening thematically. The violence is not gory the way Chainsaw Man is — there’s no blood-and-body-horror element — but it gets loud and visually overwhelming in the action sequences.
If you’re watching with a kid who’s 8 to 10 years old, Season 1 is probably fine. The tone is mostly lighthearted, the violence is clearly fantastical, and Mob’s core dilemma — being afraid of your own emotions — is actually pretty relatable content for that age group. I’d say Season 1 is watchable together if your kid is old enough to follow a story and okay with big action sequences.
By Season 2 and especially Season 3 the emotional complexity ramps up. I’d want Tanner to be at least 9 or 10 before trying those. And I’d want to watch Season 1 with him first to see how he handles it.
Not yet. But I’ve already put it on the list for later.
Where to Watch and What to Read
Mob Psycho 100 is on Crunchyroll — all three seasons, all in one place. That’s the cleanest way to watch it from start to finish.
The manga is also worth your time. ONE wrote it in the same deliberately rough webcomic style as the original OPM webcomic — simple art, strong writing — and the anime is a faithful adaptation, so going to the manga is more about extending the experience than correcting the adaptation. It’s a good read if you want more time with Mob after the show ends.
Mob Psycho 100 manga Vol. 1 starts at the beginning and covers the same ground the anime does, which is worth it if you want the source version or if you want to reread it with the anime’s interpretation fresh in your head. If you want to go further or own a nice collected run, Mob Psycho 100 manga complete set is a good option — the full story in one collection.
The Short Version
Watch order: Season 1 → Reigen OVA (optional) → Season 2 → Season 3.
Should you watch it before or after OPM? Either works, but I watched OPM first and it made me appreciate what Mob Psycho was doing by contrast. Knowing that both shows are by ONE and watching how differently he handles the same basic premise — overpowered protagonist, what do you do with that — made me like both shows more. I’d say watch OPM first if you haven’t, then come here. If you’ve already seen OPM, start Mob Psycho 100 immediately.
Don’t be me. Don’t wait five recommendations before you believe people.
