Machine Wars was a line of Transformers toys released in 1997 as a Kay-Bee Toy Works exclusive. Apparently, the line was an early attempt to bring vehicular characters and popular names back into Transformers after the success of Beast Wars revived the brand. Only one wave of figures was produced, and memory of the line has mostly faded. It is a rare example of a micro-continuity (and, specifically, an implied continuity) which nevertheless had a full (albeit very small) toyline of its own.
