Passein was conquered by Frieza in Age 621 and was renamed Planet Frieza 023. Its native species, the Legutholo, were enslaved and several Planet Trade Organization outposts were placed across the world. This world mainly functioned as a military outpost, with several cities being used solely to train soldiers. Additionally, the planet was valuable for rare metal mining, and several such mines were set up across the surface, particularly near the north pole.
In Age 701, an infestation of space-badgers led to the deaths of all PTO soldiers as well as native Legutholos within six months of the spread. Years later, Cui was sent to the planet to cleanse it of its infestation, and he was mostly successful in doing so. As of the time of Monster, which took place about two decades after the outbreak, the Planet Trade Organization was re-populating the planet, but many of the cities were still uninhabited.
- Frieza, Kuriza, and Lingon once stayed at this planet for two weeks during the events of Monster. Frieza's "palace" was actually an abandoned warehouse, as the local soldiers had not had enough time to build him one before he arrived.
- Lingon was born on this planet.
- Cui was not entirely successful at eliminating the space-badger infestation, as during the events of Monster, Kuriza spotted at least one feral space-badger rummaging through the trash outside.
