Minor Characters/Corrupted Gems

Minor Corrupted Gem Characters are Corrupted Gems who have debuted but, as of yet, hold no significant or recurring roles.

Centipeetle's Crew


The Centipeetle's Crew includes two Corrupted Gems that appear in "Monster Reunion". Their bodies and gemstones are the same as the corrupted Centipeetle, implying they are the same Gem type. Interestingly, the bands around the gemstone's of the Centipeetle's crew are not curved, suggesting they did not damage their gemstones being in the safety of the ship.

They did not evacuate Earth when ordered to as they did not want to leave their captain behind, and as a result they also became corrupted. As of now, they live together in the Ancient Gem Colony Ship.

Water Bear Monsters
The Water Bears are a group of similar-looking Corrupted Gems, with individuals appearing in "Love Letters" and "Earthlings". Their designs' similarities imply they are the same Gem type.

They have barrel-shaped bodies with three similarly-colored pairs of short stubby legs on their sides. Four finger-like appendages accompany on each leg. Their entire body mass, aside from their conical gemstone, seems to be composed of a gelatinous substance.

Water Bear


The Water Bear is a corrupted Gem that first appeared in "Love Letters". In the episode, the Water Bear presumably attacks Garnet during her search for Malachite in the ocean, and is brought up to the surface.

Her light-blue body contains a lavender-violet conical gemstone located in her head, resembling a single eye.

Beta Kindergarten Water Bear


The Beta Kindergarten Water Bear is a Corrupted Gem that appeared in "Earthlings".

Her sea-foam green body contains a teal conical gemstone located in her head, resembling a single eye. Her similar design to the Water Bear from "Love Letters" implies they are the same Gem type.

Jasper originally incarcerated them as she was forming her Corrupted Gem army to take on the Crystal Gems. Jasper accidentally frees the Corrupted Gems when she crashed into a cliff face and knocked several free from their cells.

Their current status is unknown after running off, but they are assumed to be somewhere near the Beta Kindergarten.

Beta Kindergarten Quartz Monsters
The Beta Kindergarten Quartz Monsters are Corrupted Gems that appeared in the episode "Earthlings". Their designs' similarities to other Corrupted Gems (including the corrupted form of Jasper) imply they are Quartz.

Purple Striped Beta Kindergarten Monster

Ant Gem Monster

She has at least four circles as her body with each one having two legs, and her gemstone is on her mouth. She does not have any eyes, and her coloration is unknown.

Red Bird Gem Monster
The Red Bird Gem Monster is a Corrupted Gem that appeared in Issue 1 of the Steven Universe comics, seen briefly in one panel sitting atop a nest. Although her current status is unknown it can be assumed that she was poofed and bubbled since Steven asked Lapis Lazuli to remind him to tell Garnet about the creature later. She appears as a regular light-red bird with a brown beak. She seems to lack any eyes and has a wing-shaped tuft of feathers on the crown of her head. Her faceted red gemstone is on her chest.

Slime Gem Monster
The Slime Gem Monster is a Corrupted Gem that appeared in Steven Universe: The Big Donut Special. She crashed into the Big Donut with the Crystal Gems whilst Sadie and Lars attempted to clean up the mess left behind by their battle to pass a health inspection. She is currently bubbled after being defeated by Amethyst. The Slime Gem Monster appears as a long teal worm encased in a slimy pale green membrane. The membrane forms multiple legs and a pincer that the body of the worm itself does not have. She has a hexagonal golden gemstone located on her featureless face, however when she is poofed her gemstone is purple, suggesting that either the slimy membrane tints the actual colors of the gem monster or the gem is possibly reflective because Amethyst was holding it.

Tentacle Monster
A spiky tentacle/tail can be seen in the beginning of Issue 7 during a fight against Pearl.
