Kamen Rider Kabuto: God Speed Love (2006)

This movie takes place in an alternate universe (where its storyline could be considered a prequel to the events of the TV series). In 1999, an enormous meteor crashed onto Earth carrying extra-terrestrial creatures. In order to counter this new threat, ZECT was formed. Seven years later, in the year 2006, power struggles in ZECT have caused a new group, known as Neo-ZECT. With three groups in existence (Neo-ZECT, ZECT and the Worms), Tendou has decided to sell his power to either Neo-ZECT or ZECT, but his intentions are unclear. ZECT reveal a plan to save humanity, but unknown to other is a plot to destroy man kind.
