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, with a small visible iris. She is only seen through Ronaldo's night vision camera, therefore the actual color of her shell is unknown. In the palette seen, she appears to be a dark teal color, although she could be orange and white, like her minions. She has two mandibles on her front acting as a mouth.
Uncorrupted
In her uncorrupted form, she has red, tan, and white coloring. She appears to wear a helmet with four spikes on top and a short bobbed hairstyle. She has one large eye and one pointed tooth. She has broad shoulders and still possesses a large claw on her right arm, with her left arm having four pointed fingers. Most of her body is covered in a reddish exoskeleton not unlike that of her corrupted form (an apparent corruption scar much like her claw), with discernable segments on her elbows and knees.
Abilities
Precise Cutting: When uncorrupted, Bixbite has been shown to have a knack for making the perfect cut, as shown in "Guidance", where she perfectly sliced up a pizza.
Creature Creation: At least while corrupted, Bixbite can generate smaller Crab Monsters.
Bixbite in her corrupted form resembles Gohma from the Zelda series, particularly in how she seems to use her claws to help protect her eye, which is her weak spot as well as her ability to spawn smaller versions of herself.
Bixbite is similar to Nephrite in her corrupted state, and the Gem Cave Creature, in the sense that she is able to summon smaller versions of herself.
The model sheets accessed by Quidd incorrectly listed her corrupted form as "Aventurine". However, her name was confirmed as Bixbite in "Guidance".
Bixbite has a primarily red-and-yellow design, despite bixbite being a pinkish-red gem in real life.
Her gemstone is shaped like an upside-down teardrop. Due to her real palette being unknown, her Gemstone appears in a green-blue hue due to the palette in "Rising Tides, Crashing Skies".
