Crossovers are anime/manga series or specials in which characters from different universes meet and interact. As such, they are non-canon. Questions about crossovers in general, or about specific plot elements of a particular crossover, should be tagged with this.

Crossovers are anime/manga series or specials in which characters (or occasionally concepts) from different universes meet and interact. As such, they are non-canon. Questions about crossovers in general, or about specific plot elements of a particular crossover, should be tagged with this.

Note: This is different from two unrelated series in the same universe (e.g. Baccano! and Durarara!!). It's also different from cameo appearances of characters outside their original universe, and from references to characters from a different universe. For a particular series to be a crossover, each universe should have an impact on what occurs.

Examples: Mazinger Z Vs. Devilman, Lupin III vs. Detective Conan, One Piece x Toriko, Fate/Stay Night x Magical Girl Lyrical Nanoha
