Ropponmatsu Unit 1  

Robot Matsu

The Ropponmatsu Unit 1 is designed as a general-purpose tool for Kabapu and excels at bomb disposal. After failing in its first mission, it receives an additional form - that of a perky young cat-girl. In the manga, only one active Ropponmatsu unit exists at any given time; this is because there is only one central "core" that switches between the two bodies. Kabapu claims that the core contains the soul of the princess of the lost civilization of Solaria and has had the Ropponmatsu body created to house it as part of his plan to destroy all remaining traces of Solarias technology. On the other hand, the anime portrays the Ropponmatsus as two distinct entities who frequently cooperate on important tasks. Despite this, both incarnations of Ropponmatsu tend to fail in their duties due to either extreme mass (Unit 1) or a lack of appropriate functionality (Unit 2).
