HM Mech Rosa is a robot from the Nintendo DS video game Chōsōjū Mecha MG, released exclusively in Japan. It has two different transformations including its humanoid form and bulldozer form. While it is unable to wield weapons, a negative aspect not shared by most Marionation Gears, it is appreciated among pilots for its ability to transport heavy objects. It was built by a team under Professor Doran.
"A heavy-class mech able to transform between humanoid and bulldozer forms. The Rosa cannot carry weapons, but it's ideally suited for transporting goods. This MG was developed by the Heavy- Machinery Workshop, founded by Professor Doran and specializing in heavy-machinery MGs like cranes, dump trucks, and mixers. Of course, all transform into humanoid form."
