New information on Space Sheriff Gavan: THE MOVIE has been leaked! The following is a summary of the plot as well as cast info.

Fifteen years ago, three childhood friends, Geki, Sherry and Okuma, were star-gazing and became inspired to go into space. As adults, Geki and Okuma join a mission to Mars, but their space shuttle goes missing before they could reach their destination. A year later, a monster attacks and a mysterious silver-colored warrior appears.

Retsu (the original Gavan) is now a special detective for the Galactic Federation Police and is training Geki as his replacement. Sherry joins SARD, an organization who’s mission is to help further space exploration and works alongside JAXA. She helps design a new Dolgiran with SARD. Sherry’s aunt, Eleena, is the secretary to Commander Com, the leader of the Galactic Federation Police. Itsuki, another childhood friend of Geki, joins SARD as a Physics Research Developer.

Gavan has a new attack called the Gavan Hyper Dynamic. The Space Mafia Maku returns and plans on creating a wormhole. The Lizard Doubler monster is currently being dealt with by two other famous Space Sheriffs
