Movie War

This article is about a series of movies in the Kamen Rider Series.

The Movie War Series (MOVIE（ムービー）大戦シリーズ, Mūbī Taisen Shirīzu) is a series of crossover films between two immediate installments of the Kamen Rider franchise, having started with W and Decade. Typically, these movies premiere around mid-December and are treated as Winter Movies.

Individual films since the Generations Series and beyond have discarded the Movie War title, though they continue to follow the traditional crossover format as established by the earlier Movie War films.

Multi-Act Format[]

Each film of the series is presented in several acts:

The first act is dedicated to the recently finished series and usually serves as an epilogue that follows the story of the characters after the events of their final episodes.
The second act is dedicated to the incumbent series and usually serves to tell an additional side-story involving the characters, allowing them to be developed in ways that do not make it on television.
The third and final act combines the narratives of both parts where both protagonist Riders team-up to defeat a combination of their respective enemies.

In rarer occasions, the incumbent and previous series switch act placements, and the second act is seamlessly combined with the final act.

Notes[]

The Movie War series can be considered the Kamen Rider Series' equivalent to the VS. movies of Super Sentai, which had celebrated its 15th anniversary before the start of the Movie War Series.
Most Movie War films feature Legend Rider versions of the Kamen Riders' Collectible Devices. In some cases, the main Riders of each respective seasons will exchange powers; this may also occur in a one-sided manner where only one main Rider adopts the powersets of the other.
