This transformation belt is the central device used by the protagonists of the Japanese tokusatsu series, Kamen Rider W. It utilizes two USB-shaped devices called Gaia Memories, inserting them into the belt to initiate transformation into the titular hero. For example, the Cyclone and Joker Memories combine to create Kamen Rider Ws base form.
The dual-memory system introduced a unique aspect to the franchise, allowing for a wide array of combination forms, each possessing distinct powers and abilities. This innovative mechanism added depth to the characters and storylines, influencing subsequent series in the franchise. Its introduction marked a notable point in the franchise’s history, contributing significantly to its ongoing popularity.
