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.

* Herr Fiend is shown as 'Herr-Fiend' with a hyphen in some catalogues showing Super Machine Men.
While the Super Machine Men figure guides showed the blue painted Herr Fiend, these guides are often inaccurate and until a boxed example is available the colour remains unconfirmed.
** A DX Robo Machine box in the horizontal photograph format was produced showing the matte blue Japanese release. It's unconfirmed whether only the metallic light blue version was packed in this box or whether the matte blue was ever distributed to Europe in this packaging.
*** This model was named DX Coup on the packaging front and DX Sports Car II in the model listing on the back.
