Ice Monster

The Ice Monster is a former corrupted Gem that first appeared in "Monster Buddies". BlueWhiteLight and Redchael has designed an uncorrupted form called "Celestine". Ultimately, it eventually turned out that her real name is "Larimar".

Corrupted
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.

Uncorrupted
In her normal, uncorrupted state, she has a sky blue complexion, as well as a prism shaped head with three spikes on top. She also has claws, instead of normal fingers (possibly corruption scars). She wears a blue shirt with elbow-length sleeves as well as puffy dark blue shorts and a pair of blue knee length boots with dark blue spots on them. She also wears a round light blue scarf/collar around her neck.

Personality
Nothing is known about her personality yet.

Abilities
Larimar possesses standard Gem abilities including bubbling, shapeshifting, fusion, regeneration, agelessness and superhuman strength/durability.

Monster Buddies
The Crystal Gems are shown fighting Larimar in the large cavern inside a snowy mountain. She's 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 Larimar. Pearl bubbles her gem and transports it back to the Burning Room. Her gem is seen again when Garnet bubbles Steven to the Burning Room and is later seen again when Steven bubbles Nephrite's gemstone to the room along with the "Chaaaaps".

Trivia

 * Larimar, as well as a stronger version of her, appear as antagonists in the Steven Universe flash game, "Sword Dancers".
 * Larimar's corrupted form bears a resemblance to a Freezie from the Super Mario series, except she has arms and legs.

 * Larimar is a type of pectolite or a rock composed largely of pectolite, an acid silicate hydrate of calcium and sodium. Pectolite is found in many locations, but larimar has a unique volcanic blue coloration, which is the result of copper substitution for calcium.
 * Miocene volcanic rocks, andesites and basalts, erupted within the limestones of the south coast of the island. These rocks contained cavities or vugs which were later filled with a variety of minerals, including the blue pectolite. These pectolite cavity fillings are a secondary occurrence within the volcanic flows, dikes, and plugs. When these rocks erode, the pectolite fillings are carried down the slope to end up in the alluvium and the beach gravels. The Bahoruco River carried the pectolite-bearing sediments to the sea. The tumbling action along the streambed provided the natural polishing to the blue larimar, which makes them stand out in contrast to the dark gravels of the streambed.
