Gem Monsters

The Gem Monsters, also known as Corrupted Gems, are recurring antagonists of the Cartoon Network TV series, Steven Universe.

Throughout the series, The Crystal Gems hunt, collect and bubble their gemstones to their temple to keep Earth safe from them. They take on monstrous forms and have special abilities. Some of them like the Centipeetle Mother and Big Bird are able to make smaller copies of themselves. In Ocean Gem, it's revealed that the Gem Monsters are corrupted gems who were former Crystal Gems and possibly Homeworld Gems who became unable to sustain sentience and humanoid forms due to an unknown cause.
