RoboForce was a LEGO Space subtheme released in 1997 that consisted of only 4 sets and only appeared in US LEGO catalogs. The sets featured various large robots in two color schemes, Orange Class robots which featured a police-like patrol function, and Green Class robots that featured a more militaristic theme with animal shaped robots.
1997 LEGO Sets
1997 saw LEGO’s first major sales decline, prompting experimentation and digital expansion. LEGO Island introduced the brand’s first open-world video game, setting the stage for future digital storytelling. New subthemes included Divers for underwater exploration, Fright Knights for gothic medieval fantasy, and Time Twisters as a sequel to Time Cruisers. LEGO Space added Roboforce and UFO, shifting toward alien-focused designs, while Aquazone expanded with Aquaraiders. Despite challenges, LEGO’s creativity remained strong across both physical and emerging digital platforms.
