Futuron was a LEGO Space line of 1987 to 1989 and the direct successor of Classic Space, with the same planet logo on its astronauts and a white and blue colour scheme with transparent yellow canopies. The minifigures wore new printed suits in four colours. Futuron arrived in the same year as Blacktron, the first space villains, and the catalogues showed the two sides racing each other.

Its best known set is 6990 Monorail Transport System from 1987, a motorised monorail with a station and a raised track, which was the first of the LEGO monorails. Futuron also had 6953 Cosmic Laser Launcher and 6932 Stardefender 200, and it gave way to Space Police and the later space lines in 1989.
