|First Appearance/Mention:||Horror of the Asterozoids|
Asteroz is an ocean planet that was once the home of the Asterozoids. After centuries of over-fishing and the spread of hypoxic "dead zones", it became uninhabitable for all its aquatic species. The Asterozoids were forced to migrate and have since trawled the galaxy for new fishing grounds. They encountered the Fourth Inspector when they attempted to convert the Earth's oceans into aquacultures for their traditional Asterozan livestock, such as the Morgawr.
