In a former question it was pointed Mob appears in a cover photo of a One Punch Man manga. Does Mob appear in One Punch Man? . But also apparently Tatsumaki appears in a Mob Psycho manga (I've seen the anime but I havent read the manga), in an apparent scene of the manga itself, not a cover Tatsumaki in Mob Psycho 100

Do Mob, Tatsumaki and Saitama live in the same universe/planet kinda like Goku and Arale from Dragon Ball / Dr Slump ?

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.

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.

    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. Aug 27, 2019 at 14:34
  • well, this was based on my opinion~

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


For me, i think that they are in the same universe and i have PROOF as you remember the episode that mob and his sensei reigen fought the ghost in a tunnel in the first season his sensei reigen suddenly got scared and suddenly released his phone quickly and show his phone to the screen with saitama's face to try to call him if something bad happens heres the link of the vid
