• In general, any Intercontinuity Crossover that acts as though the characters from both companies involved have always been part of a single shared universe tends to fall into this. Examples like Superman vs. the Amazing Spider-Man, The Uncanny X-Men and the New Teen Titans and Batman vs. The Incredible Hulk operate on the premise that the characters of the Marvel and DC Universes have always coexisted in the same continuity, but simply never encountered one another until then, despite the obvious questions this raises. Lampshaded in The Incredible Hulk vs. Superman, where Lois Lane asks how the Avengers can possibly call themselves "Earth's mightiest heroes" when Superman has never joined their ranks.
