In 1989, LEGO made a storyline decision. Blacktron, previously operating in a moral void, were now declared the "bad guys" of Space; opposing them and defending the civilian Futuron from them were the Space Police, a group of brave individuals whose spacecraft were black and blue with red transparent brick elements. (This would be a continuing theme of space, having "bad guy" space races, "good guy" space races, with "civilian" space races between them.) Space Police re-introduced the idea of modular systems, on a smaller but also grander scale.
The Space Police theme features three spaceships, two wheeled vehicles and a ground-based space station; all but the smallest buggy comes with a Space Police jail cell (which was often supplied with a Blacktron occupant). These jail cells were identical from set to set, and had the ability be traded around between vehicles with no hassle whatsoever.
This theme marks the beginning of LEGO Space's greatest period of success, and is one of the most well-loved themes of the collection; complete models of the largest ship, 6986 Mission Commander, have been known to sell for $90, via online vendors.
