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
In 1997, the LEGO Group faced significant challenges as it grappled with a changing toy market and internal organizational shifts. While the company introduced its first-ever licensed theme, "Star Wars," laying the groundwork for one of its most successful and enduring lines, it also experienced a dip in sales for the first time since its inception. The LEGO Group recognized the need to innovate and diversify its product offerings beyond traditional brick sets, leading to endeavors in new areas like software and video games, with the launch of LEGO Island, its first PC game. This year marked a period of introspection and transformation for the iconic toy company.
