Cereal (シリアル星 Shiriaru-sei) is the native planet of the Cerealians.
Cereal was conquered by the Frieza Force and the Saiyan Army, who utilized the full moon to transform into Great Apes and annihilate nearly all of the population and their cities. Following this, the Heeters, who secretly made a deal with the Frieza Force as business partners to ravage Cereal, arrived to the planet and began to rebuild it. The Sugarians, having no planet of their own, paid the Heeters so that they could populate there unaware that they were scammed by them.
- Cereal's name is based on cereal, a breakfast meal.
