I'd more accurately call it a cameo, the same way that some main characters from Makoto Shinkai's films show up in his later works. Osamu Tezuka (creator of Astro Boy and Kimba the White Lion) famously used his characters like actors so it wasn't unusual for them to show up in multiple, completely different works.

Not sure why, but your answer says No, then seems to show the contrary.  Only until I get to the bottom and read the other comment does it make any congruency.

<p>I don’t believe they live in the same universe since in season one episode two someone is seen reading one punch man not to mention saitama appears on the back of a mc Donald’s bag in episode three (or Mob’ Donald’s because copyright) so it seems saitama is just a novelty character in mobs universe</p>

In episode 7 of Mob Psycho season 3, we also see Saitama as the background image on Mob's cell phone: https://i.sstatic.net/AhznL.jpg

<p>To elaborate on <a href="https://anime.stackexchange.com/a/54100/19307">kit's</a> answer, the worlds of <em>Mob Psycho</em> and <em>One Punch Man</em> have incompatible canon. Psychic powers exist in <em>One Punch Man</em>, but other kinds of heroes do not exist as far as we know in <em>Mob Psycho</em>. Additionally, powers are public knowledge in <em>One Punch Man</em> since there is a hero bureau that protects everyone, and there are monster threats and such that cause very large amounts of damage, but psychic powers are a secret to the public in <em>Mob Psycho</em>. We can see this in Reigen's initial reaction to Mob, since he doesn't believe him when he says he has psychic powers. If he lived in <em>One Punch Man</em>'s world, then he wouldn't have been so skeptical about the <em>existence</em> of psychic powers, but would have focused his skepticism on whether Mob in particular had them. From what I recall, his reaction was very much of someone who did not believe psychic powers exist at all.</p>
<p>Thus, it is most likely that the appearances of the characters in each others' universes are simply cameos. You can ignore them as far as canon goes, or you can simply assume a different version of Mob exists in <em>One Punch Man</em>. As far as Saitama appearing in <em>Mob Psycho</em>, he could be a fictional character if he only appears on cell phones and stuff. And it's worth noting that Saitama isn't famous in his world, so it doesn't really make sense for people to be using him as their cellphone wallpaper (it's possible to work around this, but due to the unlikelihood, it points to this probably not being the universe of <em>One Punch Man</em>.)</p>
<p>Regarding Arale, she also presents canon inconsistencies to the <em>Dragon Ball</em> universe. She may have meshed better with the original <em>Dragon Ball</em>, but by the time of the <em>Dragon Ball Super</em> episode she appeared in, the tone of the series has changed a lot, to the point where that episode felt a bit like a non sequitur. Vegeta even ends up getting self-referential and meta when he starts calling her a &quot;character from an 80s gag manga&quot;. <em>Dragon Ball Z</em> and <em>Dragon Ball Super</em> aren't usually that meta, so it's kind of hard to determine how canonical that episode was, and thus how canonical Arale living in the same world is. The canon of <em>Dragon Ball</em> also presents some problems to <em>Dr. Slump</em>. Has Arale now died at least once, via Majin Buu?</p>
<p>Due to these inconsistencies, we can't really conclude anything definite with regards to the canons of any of these series.</p>

The answer is **NO**.

Saitama's world and Mob's world is totally different. We can see that the art style of the anime and the main character is almost alike that's because they were written by the same creator, [**ONE**](https://en.wikipedia.org/wiki/One_(manga_artist)).

Mob appear in One Punch Man world.

Saitama appear in Mob Season 2 Opening. (Watch the cellphone, it's Saitama outfit.)

So why does these 2 not related story will appear on each other scene, I guess it was just a purely an advertisement purpose.

To elaborate on [kit's](https://anime.stackexchange.com/a/54100/19307) answer, the worlds of *Mob Psycho* and *One Punch Man* have incompatible canon. Psychic powers exist in *One Punch Man*, but other kinds of heroes do not exist as far as we know in *Mob Psycho*. Additionally, powers are public knowledge in *One Punch Man* since there is a hero bureau that protects everyone, and there are monster threats and such that cause very large amounts of damage, but psychic powers are a secret to the public in *Mob Psycho*. We can see this in Reigen's initial reaction to Mob, since he doesn't believe him when he says he has psychic powers. If he lived in *One Punch Man*'s world, then he wouldn't have been so skeptical about the *existence* of psychic powers, but would have focused his skepticism on whether Mob in particular had them. From what I recall, his reaction was very much of someone who did not believe psychic powers exist at all.

Thus, it is most likely that the appearances of the characters in each others' universes are simply cameos. You can ignore them as far as canon goes, or you can simply assume a different version of Mob exists in *One Punch Man*. As far as Saitama appearing in *Mob Psycho*, he could be a fictional character if he only appears on cell phones and stuff. And it's worth noting that Saitama isn't famous in his world, so it doesn't really make sense for people to be using him as their cellphone wallpaper (it's possible to work around this, but due to the unlikelihood, it points to this probably not being the universe of *One Punch Man*.)

Regarding Arale, she also presents canon inconsistencies to the *Dragon Ball* universe. She may have meshed better with the original *Dragon Ball*, but by the time of the *Dragon Ball Super* episode she appeared in, the tone of the series has changed a lot, to the point where that episode felt a bit like a non sequitur. Vegeta even ends up getting self-referential and meta when he starts calling her a "character from an 80s gag manga". *Dragon Ball Z* and *Dragon Ball Super* aren't usually that meta, so it's kind of hard to determine how canonical that episode was, and thus how canonical Arale living in the same world is.
