First released in Japan by Bandai as part of the Machine Robo Series range these larger scale, mostly highly detailed models were quickly added to the US Gobots, EU Robo Machine and AU Machine Men lines.
The Machine Robo Scale Robo, Machine Robo DX and Big Machine Robo lines, loosely became Super Gobots Series 1 and 2 while Series 3 also having been designed in Japan were not released for the Japanese market. Series 3 Super Gobots see the most US / EU variants and as more than half of the series were produced in limited numbers, some very limited they have become very collector desirable.
