UFO was a LEGO Space subtheme of 1997 and 1998 about alien cyborgs in flying saucers with bright transparent green canopies. Its figures had printed cyborg faces and new helmets, and the ships used large moulded panels and dish shapes made only for this line, which gave them a look unlike any LEGO space ship before. 6900 Cyber Saucer was the largest, a full flying saucer, and smaller craft such as the V-Wing Fighter and the Cyborg Scout filled out the range. UFO ran alongside Roboforce and gave way to Insectoids in 1998.
1998 LEGO Sets
1998 marked LEGO’s leap into programmable play with the launch of LEGO Mindstorms, combining motors, sensors, and code for user-built robots. LEGO also entered digital entertainment with games like LEGO Creator, LEGO Loco, and LEGO Chess. New themes included Adventurers, following Johnny Thunder’s global expeditions, and Insectoids, a sci-fi successor to Exploriens. LEGO Castle revisited classic factions such as Crusaders and Dragon Masters, reconnecting with its medieval roots while bridging into modern set design.
