Minor Characters/Corrupted Gems

Minor Corrupted Gem Characters are Corrupted Gems who have debuted and been identified, but, as of yet, hold no significant nor recurring roles.

Centipeetle's Crew
The Centipeetle's Crew are two corrupted Gems that appear in "Monster Reunion". Their bodies and gemstones are the same as Centi, showing that they are the same Gem type as her. They have been waiting for the Centipeetle Mother, because they didn't want to leave her behind. As of now, they live together in the Ancient Gem Colony Ship.

Cobbled Beta Kindergarten Monster
The Cobbled Beta Kindergarten Monster is a corrupted Gem that appeared in the episode "Earthlings".

She was originally kept imprisoned by Jasper as she was forming her Corrupted Gem army to attempt to take on the Crystal Gems and swiped at Steven when the cages were discovered by him, Amethyst, and Peridot when he strayed too close. She was freed alongside many other members of this army when Jasper herself crashed into a cliff face, knocking several of them free from their cells.

Her current status is unknown, as she has not since been seen after running off. She's assumed to be in the local area of the Beta Kindergarten. She is extremely similar to many other monsters of similar gem-design and morphology, including Jasper's current form, which may mean that she, as well as her kind, are Quartz.

Ice Monster
The Ice Monster is a Gem Monster that first appeared in "Monster Buddies". She possesses a bulky body that is colored varying icy shades of blue. The creature also possesses two, very large arms with four spiky fingers each and two short legs. Her head is carved into five, sharp protrusions. She has two dark, hexagonal eyes and a gaping, dark mouth lined with sharp teeth. This monster is slightly taller than Garnet.

In "Monster Buddies", The Crystal Gems are shown fighting this monster in a large cavern inside a snowy mountain. She is shown to be preventing them from acquiring a powerful, elemental artifact called the Shooting Star. After her arm falls off, Garnet deals the final blow on her, thus, defeating the monster. Pearl bubbles her gem and transports it back to the Burning Room.

The Ice Monster, as well as a stronger version of the Ice Monster, appear as antagonists in the Steven Universe flash game, "Sword Dancers".

Water Bear
The Water Bear is a corrupted Gem that first appeared in "Love Letters". She resembles a light-blue, barrel-shaped body with three similarly colored pairs of short stubby legs on her sides. Each leg is equipped with four finger-like appendages. Her entire body mass, aside from her gemstone, is composed of a gelatinous substance. Her gemstone is conical in shape and is located in her head, resembling a single eye. The gem is lavender-violet. In the episode, the Water Bear presumably attacks Garnet during her search for Malachite in the ocean, and is brought up to the surface. For unknown reasons, she is thrown back into the water instead of being poofed and bubbled. Her current status is unknown.

Crab Gem Monster
The Crab Gem Monster is a corrupted Gem that first appeared in "Rising Tides, Crashing Skies". She resembles a large crab. She has two large claws and six legs. On the top of her head, she has four small horns and in the center is one large spike. She has only one eyeball, and her iris appears to be the gemstone. Because she's only seen through Ronaldo's night vision camera, the actual color is unknown, but in the palette we see, she appears to be a dark teal color. She could be orange and white, just like her minions. She has two small pincers at her front, which is her mouth. The crab gem monster can create smaller crab monsters, one of which pinched Ronaldo before the main monster was introduced.

Earth Beetle
The Earth Beetle is a corrupted Gem that makes her first appearance in "Giant Woman". Garnet had found her while Steven, Pearl, and Amethyst searched for the Heaven Beetle.

The Earth Beetle's figure somewhat looks like that of a Japanese Rhinoceros Beetle. The Earth Beetle's femurs are black, and the lower half of her legs are black. Her body is mostly a lightish-gray, but has a pale green gem on the top center of her body which is surrounded by a clover shape that is dark gray. She also has a black horn, black eyes, and black antlers.

Unknown Giant Gem Monster
The Unknown Giant Gem Monster is a corrupted Gem that first appears in "Beach City or Bust", a play put on by Jamie and Steven in "Historical Friction", portraying her defeat at the hands of an unknown Crystal Gem fusion. Her current status is unknown, but it can be assumed that she was probably poofed and bubbled.

She had at least four tentacles, and at least two more longer tentacles. Her head resembles the Centipeetle Mother and Big Bird. The Unknown Giant Gem Monster appears to be aquatic.

Trivia

 * The Water Bear seems to be based on a tardigrade.
 * Tardigrades can live for a long time without nourishment, usually up to 30 years. They are also extremely durable as they can survive in the vacuum of space by entering a state of suspended animation.
 * Tardigrades are so small that they are barely visible to the human eye.
 * Another name for tardigrades is "Water Bears".
 * Another Water Bear appears in "Earthlings", however her gemstone is teal rather than lavender-violet and has a sea-foam green body instead of a light-blue one. Because of their similarities, they may be the same Gem type.


 * The Crab Gem Monster, as well as the Small Crab Monsters, resemble Gohma from the Zelda series, particularly in how it seems to use her claws to help protect her eye, which is her weak spot, and her ability to spawn smaller versions of herself.
 * The Earth Beetle, along with the Heaven Beetle, are collectively known as "The Geode Beetles of Heaven and Earth".
 * The Earth Beetle appears in the desktop game "Goat Guardian" as a power up that lets Steven jump twice, instead of once.
 * It was confirmed that the Earth Beetle, along with the Heaven Beetle, are corrupted Gems.
 * The Heaven Beetle appears to have a gemstone identical to the Earth Beetle's.
 * The design of the Heaven and Earth beetles resembles the real life practice of live insect jewelry.
 * She and the Heaven Beetle are the second and third corrupted Gems that are shown bubbled without being poofed first. The first is the Desert Glass.
 * Due to their similar appearance, is can be inferred that they're within the same gem type.
 * Both the Orange Great North Monster and Snow Monster resemble each other, indicating that they may in fact be the same type of Gem. They are also shown to resemble the Corrupted Jasper, and Jasper believed them to be Quartz Gems like herself. However, it is unknown if this resemblance to Jasper's Corrupted form is due to them being Quartz Gems like Jasper or if the similarities are due to Jasper's corruption originating from her fusion with the Green Great Northern Monster.
