Solid

Solid (ソリッド Soriddo) is a planet in the Yurina System. It is nearly completely covered by an ocean of salt water giving it a turquoise color when seen from space. Large organic lifeforms such as Gōmya and Dōmya inhabit the shores of a small landmass amidst this ocean and Solid normally has a warm, tropical ecosystem. Break and Stampy remark that it is a notably beautiful planet.

After having been berated by his older brother, Gōmya's rage combined with the energy enclosed within an Angolmois capsule, having recently landed on-planet, caused the entire planet the freeze over. Break was excited to finally visit an icy world, everyone else, not so much. As the Predacon and Maximal forces skirmished over the capsule, Gōmya was able to let go of his feelings of resentment towards his sibling, causing the capsule's effect over the planet to wane, and the ice to thaw, returning Solid to its natural state.
