Roboforce was a subtheme of LEGO Space in 1997. It appeared only in US catalogues in 1997.
Details[]
Taking the "good guy" role in the Space theme, Roboforce was a four-set subtheme which featured various large robots (arguably mecha) in two colour schemes. Orange Class robots featured a police-like patrol function in humanoid robots, equipped with buzz saws for extracting criminals or rescuing civilians. The "head" of each robot was also a small spaceship that could be used as an escape pod or secondary vehicle. Green Class robots featured a more militaristic theme with animal shaped robots. The Robo Raptor was the only set not to feature a space craft, while the Robo Master's small starcraft strongly resembled the Unitron Star Hawk II as a tribute to the fan-favorite set. Roboforce "Robos" were powered by "secret Robo Disks" which were, despite the name, rectangular power sources. Only four sets were produced under the Roboforce subtheme:
- Orange Class: Small Variant Robo Raider (1997)
- Orange Class: Large Variant Robo Stalker (1997)
- Green Class: Small Variant Robo Raptor (1997)
- Green Class: Large Variant Robo Master (1997)
