The monster has an elongated, hexagonal gem colored a bright blue which is embedded deep in it's forehead. Its gem glows brightly while in its body. It 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. Its head is carved into five, sharp protrusions. It has two dark, hexagonal eyes and a gaping, dark mouth lined with sharp teeth. This monster is slightly taller than Garnet.

History
The Gems are shown fighting this monster in a large cavern inside a snowy mountain. This monster is shown to be stopping them from acquiring a powerful, elemental artifact called the Shooting Star. After its arm falls off, Garnet punches and defeats the monster, and Pearl bubbles its gem back to The Burning Room.
