Machine Robo
Tonka released the first batch of figures to stores in 1983, one year prior to the Transformers. The bulk of the Gobot line was taken from the Machine Robo ‘600 Series’ line of figures, which were around 5–8 cm / 2-3 inches high on average. The robot figures transformed into a mixture of generic and specific contemporary machines, plus a handful of Second World War fighter aircraft, and a number of futuristic designs. This unnamed assortment, usually referred to as ‘Regular’ Gobots, was used throughout the four years Gobots were produced, and was later supplemented by figures from the Machine Robo Devil Invaders sub-line, plus some aborted Machine Robo figures and some commissioned from Bandai by Tonka.
