Released in 1976, the Galactic Cruiser was one of the first series of vehicles put out by Mego. A boxed item, which included both an instruction and sticker sheet, was based on the Microman Space Buggy from their "Cosmo Car" series. Molded in green and grey plastic, it had many parts which fit into the numerous 5mm holes throughout its chasis.

Parts included a main body that had a front girder strip which held the steering handle bars, which in turn plugged into the front hood axle and wheel. The trike was balanced out in the back by 2 axle arms (which had 2 elbow type joints for various positioning) and 2 large rear wheels. But looking cool wasn't enough, the Cruiser also came equipped with a double barrelled spring loaded missile launcher, with 2 rubber tipped missiles. This plugged into the top of the body with a hinged joint via the 5mm peg/hole system. Another small piece called the rear insert adaptor rounded out the list of accessories, and resembled a tail pipe for the back of the body.

The Galactic Cruiser was also released molded in blue instead of green, as a 1978 Mongomery Ward's catalog exclusive. The Microman Cosmo Car series had 3 vehicles which also included one called the Sky Roader, which Mego chose not to release.
