Great Collapse is the seventh episode of Brave Police J-Decker.


A space elevator under construction suddenly begins to collapse and threatens to cause a tsunami that will wipe out large parts of coastal Pacific areas. The plan is to use J-Decker and Build Tiger, the combined form of the Build Team, to destroy the pieces before they hit the ocean. However, the Build Team are unable to form Build Tiger, leaving J-Decker to continue on alone.
