Kamen Riders' Movie Forms

In several movies of the Heisei era Kamen Rider Series, usually Summer Movies and Movie War films, the featured Riders gain access to new forms. This recent tradition started with Kamen Rider Kiva. In the real world, it is usually a means by the companies who make the TV shows to produce more merchandise for a series to boost sales as well add hype to the film's release by giving the audience something to look forward to.
