Blacktron was one of the first LEGO Space subthemes along side Futuron and released in 1987. Blacktron was the first truly themed series in Space accompanied with a storyline. It featured a large spacecraft, the Renegade, which set the tone for all future big ships by splitting into a number of smaller modules. The set designs were based around a black and yellow color scheme with transparent yellow windscreens and transparent red highlights.
