Unlike the bulk of early Transformers that drew their molds from Takara's Diaclone and Microchange toys, Omega Supreme's original form was "Super Change Robo Mechabot-1", produced by a company called Toybox. Toybox did not actually design Omega Supreme, instead commissioning his design, along with Sky Lynx, from Takara's then-rival Tomy. As mentioned above, he was not released in Japan under the Transformers brand during the original 1980s run, and it seems that he was not released in the United Kingdom, either; part of the reason for the latter omission is presumably due to the fact that the Mechabot-1 mold was licensed to a UK company called Grandstand and sold as Omegatron, part of Grandstand's Convertors toyline.
Released before the Transformers brand came to be, this is the original version of Omega Supreme; Mechabot-1. This figure was only available in Japan, and was also the reason that Omega Supreme was never released over there (until 2008 when the Encore line reissued him). The figure is complete with all six pieces of track, two small red clips, two medium red clips, and two large red clips (all usually missing in some form or another). The box is a bit rough and shows a bit of wear from age, but it is well over 30 years old and made of cardboard.
This is an original Mechabot-1 manufactured by the Toy Box toy company. There are a couple of vintage knock offs of this figure; this isn't one of them. The easiest way to tell on the box is that the KO has English writing on the lower left hand corner of the front artwork, the official version is in Japanese. On the figure, the knock off is done in various configurations of red/blue/yellow/chrome plastic while the original figure is done in a red/gray/black color scheme. As you can see this figure has the "Toy Box" maker's mark on the bottom of the tank, and also has the correct box.
