The M.A.S.K. toyline ran from 1985 to 1988, releasing four official series through those years. Each series featured a group of common vehicles with the ability to transform into armored combat vehicles. Most vehicles came with one or two drivers, and each character had a mask with a certain ability.
The first two series focused on a premise of crime-fighting between the M.A.S.K. team and the V.E.N.O.M. criminal organization. The last two series changed the premise to a racing-oriented theme, albeit still with the two teams competing against each other.
All series were produced and distributed by Kenner.
