Ceres (also designated "1 Ceres") is the smallest dwarf planet in the Solar System and the only one located in the main asteroid belt. It was the location of a Neosapien facility under the command of General Drusus. When Exofleet sent a Jumptroop unit to investigate, the resulting Battle of Ceres revealed the existence of the Neo Megas. After the exposure of the Neo Megas to Exofleet, Ceres was abandoned by the Neosapien Commonwealth.
Professor Algernon was en-route Ceres to examine the facility when Able Squad's report of the alien structure compelled him to divert to Mars. It is unknown if the Neo Megas were created at Ceres.
