General Info

M-tron was a sub-theme of LEGO Space released in 1990 and ended in 1993. With a color scheme of red, black, and transparent neon-green for the windshields, M:tron was popular among many fans. This theme also was famous for using magnets in most of its sets to add playability. M-tron was also famous for being one of few space themes to not contain weapons. M:tron was much like a space version of a fire brigade, introduced after Space Police. However, in the United States the names, descriptions and commercials all have been modified to alter this backstory. In the United States M:Tron is portrayed as a civilian faction. Speculation on what the trans-neon green rounds that the M:Tron are transporting signify as well as the fact M:Tron is based around magnets have caused American AFOLs to consider M:Tron a mining faction.
