A remolded version of the American Powermaster Optimus Prime figure, Ginrai is a red, blue and grey tractor trailer, only able to transform into robot mode when the small Ginrai human figure is put into engine mode and snapped into place in the truck's grill, unlocking the clasp that holds the legs in place. When the cab is in robot mode, the trailer can become a battle station. Either robot or station can be armed with any of the toy's weapons, including two black "Superconductor Rifles", and two grey double-barrelled "Particle Beam Cannons", (referred to as "Cannon Craft" in "The Battle Begins! The United Earth-Space Troops"), which can be piloted by any small Godmaster figures. The cab and trailer can be merged into "Super Ginrai", whose head is a separate piece, and can go on to combine with the separately sold Godbomber to become God Ginrai.
Differences between Ginrai and Powermaster Optimus Prime include retractable super-robot fists, a die-cast metal cab with translucent blue plastic windows, shortened smokestacks, a more metallic grey plastic, chrome on the Godmaster Ginrai engine, and silver paint rather than stickers for the small robot's upper legs.
Release in 1988 God Ginrai is slight re-mold of the Powermaster Optimus Prime mold. He can combine with God Bomber to form Super Ginrai. The God Bomber mold was previously unavailable in the United States until the Powermaster Optimus Prime reissue in 2003 (renamed as the Apex Armor).
The figure is in good shape, and complete. The chrome is in good shape all around, and the white bits are still white with the exception of a small spot on the chest of the Powermaster. The box shows signs of wear, has a sticker on the front, and has a rip on one of the flaps (see pics), but the foam tray is still in good shape.
