"Out-of-universe" is an adjective that refers to the perspective from which the elements of a fictional story are viewed. An out-of-universe perspective means that these elements are acknowledged as being part of a work of fiction. Compare and contrast this concept with in-universe.
The use of an out-of-universe perspective within the articles of the Marvel Database is limited to the Notes and Trivia sections. For instance, the History section of Spider-Man's article will not treat him as a fictional character created by Stan Lee and Steve Ditko, nor make direct references to the comics in which his adventures are published. Instead, the article will treat him as if he was a real vigilante living in New York City.
