Bulldozer Robo MR-11
Originally designed in Japan by Bandai and released for their Machine Robo Series line as Bulldozer Robo the model was not long after issued as Bulldozer for the European Robo Machine release and Bulldozer Man as part of Australia's Machine Men. Tonka's US rebranded 'Gobots' distribution saw Dozer given his now most established name with Bandai's the Australian Machine Men line adopting Gobots character names on figure re-release; predominantly to benefit from the Challenge of the Gobots cartoon.
Bandai did not re-release this model for their European Robo Machine distribution and so he was always sold only as Bulldozer.
Further details are below, on the Series 1 Index and for more in-depth reading see the Toy Line History page.

** Gobots Prototype: For Tonka's Gobots distribution Bandai produced prototype / sample colour variants for US market consideration. While not confirmed suspicion is they were for potential Gobots Series 2 recolour offerings similar to the orange Buggyman and blue Leader-1. While not dated the red and grey Dozer has a POPY Japan stamp vs. early orange Gobots release versions showing POPY Singapore. This places the prototype beyond the initial US orange distribution. Whether it was planned for Gobots Series 2, a mail away or other promotion isn't known. Similar variant colour prototypes were created for models specific to Series 2 and 3 Gobots.
Sticker Variant The chest stick on early Bulldozer Robo figures matches the colour scheme
on the box; green triangle, orange V. Later releases inverted this with orange triangle and green V. While unconfirmed, examples seem to point to this change having during the diagonal stripe box release that saw a mix of both sticker versions. This may have coincided with the absorption of POPY into Bandai.
