As tradition, Kamen Riders of the Heisei era always have a Hyper Battle Video, HBV for short. Of course, Fourze is no exception. This time, Kamen Rider Amazon seems to be a guest star!

Kamen Rider Amazon, whom is currently residing in the Amazon Rainforest, suddenly sees a flashing light pass him by. It strikes down in the middle of the forest and Amazon quickly decides to investigate. As he arrives at the spot, he finds an Astro Switch, very similar to the Drill Switch. Although, the color is different.
In the HBV, Fourze will be using a new mysterious State. His body is from the Rocket States, but the head is from the normal Base States! Is that a Rocket Drill on his hand!?
