Ceres is schizophrenic, he is kinda dangerous, even though he is dwarf planet. When Mars headed into the asteroid belt to find Earth's favorite asteroid, he is spooked by Ceres' stealth and cackling. He also tries to keep anyone away from him. This behavior might be the result of being alone for such a long time, as stated by Alvaro. Despite his seemingly psychotic nature, he behaves a bit vulnerably when others retaliate against him.
