Pokémon Apokélypse is a 2010 Canadian fan-made adventure short film directed by Kial Natale and produced by Dylan Innes and Lee Majdoub. Based on the Pokémon franchise, the storyline takes place several years after the events of the original anime series. Intended as a fan-response to "the common trend of 'dark and gritty' reboots of popular franchises", the film was meant to give a mature spin on Pokémon and be in the same vein as work seen on parody website CollegeHumor. The creators initially intended to reveal the film at the Vancouver Anime Evolution convention, it was not shown due to technical difficulties. Instead on September 14, 2010, it revealed online via a teaser segment distributed through emails sent to various media outlets, which presented itself as a recording of a "secret movie trailer screening" for a film in development. The full film followed shortly thereafter, posted online on September 20.

The result of almost two years of work, the film follows Ash Ketchum and his friends years after the events of the original anime series, and their struggle against criminal organization Rocket Industries. Deciding on using the subject of Pokémon after considering several possibilities such as Grand Theft Auto and Dragon Ball Z, the producers were surprised by fan reaction to the material. Despite praises for the content, they have stated they have no intention to produce a full-fledged film.

The initial "leaked" preview was met with skepticism and criticism, with CraveOnline in particular recalling the trend of past video game-inspired films being of poor quality. Kotaku and Topless Robot in particular noting that the preview did it a disservice by hiding the charm of the completed project, which by comparison was met with very positive reception. GamesRadar+ called it "amazing", and stated that the content was "good enough for grown ups"; in a further discussion, they added they were impressed by the quality of the work, and how it addressed the similarity between the games and dog fighting. Other sources such as The Escapist and Game Informer also heavily praised the production, with the former lamenting that such a concept would never officially appear from Nintendo.
