Quantic Universe

The Quantic Universe is the universe where Ladybug and Cat Noir live.

Summary
According to Thomas Astruc, "it is the extended universe in which live Ladybug and Cat Noir. Ladybug is to Quantic Universe what Spider-Man is to the Marvel-verse, or Batman to the DC-verse. Quantic Universe is filled of super-heroes in all countries, alien races, magic... Ladybug is just a tiny part of it. Hopefully, if the series is successful, we'll be able to explore it". Miraculous wielders are currently the only known type of superheroes, however, Thomas has confirmed others with abilities unrelated to Miraculouses are in existence.

Trivia

 * It is possible that Melodie, Mercury, Kid Mime, and Sparrow from Quantic Kids, a superhero team that Ladybug and Cat Noir were a part of in an unused concept, still exist in this world.
 * It is also possible that Félix, the first version of Cat Noir before Adrien, stills exists in some way there.
 * Majestia Issue #56, a comic that will appear in some way in a future episode, is published by the company Quantic Comics, which is a reference to the Quantic Universe.
 * If he isn't able to explore the Miraculous universe, Thomas has another universe he's creating.
