Marvel Universe

The Marvel Universe is a fictional shared universe where the stories in most American comic book titles and other media published by Marvel Comics take place. Superhero teams such as the Avengers, the X-Men, the Fantastic Four, the Guardians of the Galaxy, and many Marvel superheroes live in this universe, including characters such as Spider-Man, Wolverine, the Hulk, Captain America, and Iron Man. It also contains well-known supervillains such as Doctor Doom, Magneto, the Green Goblin, Loki, and Thanos. It also contains antiheroes such as Deadpool, Ghost Rider, the Punisher, Elektra, and Black Cat.

The Marvel Universe is further depicted as existing within a "multiverse" consisting of thousands of separate universes, all of which are the creations of Marvel Comics and all of which are, in a sense, "Marvel universes". In this context, "Marvel Universe" is taken to refer to the mainstream Marvel continuity, which is known as Earth-616 or Prime Earth.
