Kamen Rider Aqua

Kamen Rider Aqua is a movie-exclusive rider set to appear in Movie War MEGAMAX's OOO section.

Like Kamen Rider Poseidon, Aqua is from the future. Interestingly enough, Aqua is actually a good version of Miharu Minato, who is also Kamen Rider Poseidon.

Aqua uses Core Medals like OOO, but his belt only uses one Medal. Instead of a motorcycle, Aqua's personal vehicle is a jet ski called the Aqua Miraider.
