This universe is physically similar to our own, with the Earth, all the creatures that inhabit it, countries and cities, as well as all the other planets and space. It is also set in the same period as our own.
However, many elements exist in addition, such as characters (Tony Stark), alien technologies, genetic mutations, magical powers, etc., all of which have helped to significantly shape the world of this Universe, although they are not available to everyone.
The stories revolve mainly around the struggle between good people, called superheroes, and bad people, called supervillains (although it's not quite that simple, of course), some of whom possess supernatural powers or futuristic technologies.
Some of these vigilantes founded and joined the Avengers, the X-Men and the Fantastic Four in order to deal with threats from Earth and, above all, from outer space.
