Her name is Ceru. (pronounced "ser-oo")

Her theme music is the Glass Animals album "Zaba."

Ceru is a mythical non-existant dog creature.
Her default size is around 22 inches at her shoulder.
She has dog legs, dog paws, a dog face. 4 toes and a dewclaw on each front paw, 4 toes on each back paw. Long body. Long fluffy neck, long fluffy tail. Long, rounded, well furred ears.
Deer nose.
Intelligent ice green prasiolite eyes with slit pupils.
Her fur is a deep rich black. Slightly iridescent in the correct lighting, it may reflect green blue and/or purple.
White throat, and one white oval spot on the back of each ear.
Her nose, lips, pawpads and claws are black but the rest of her flesh is a dark dull pink. Her tongue is long, thick, and comes to a single rounded point.
Her teeth are unique. Her incisors and canines resemble that of dogs or cats, and the first premolars appear normal as well. Her second premolars are huge, perhaps assuming the role of carnivora carnassials. Her third premolars are half the size of her second. Her three molars are fused into one molar battery, around the same size as her third premolar or smaller. (Her third premolars and molar batteries are rarely seen unless she is opening her mouth very wide, i.e. yawning or roaring.) This totals 32 teeth in her mouth.

Ceru is somewhat of a spirit animal. She can float or levitate, but she cannot fly. She is capable of jumping very high, and due to her ability to levitate it can counter the earth's gravity enough that it may look similar to how one jumps on the moon.
She can speak, write, read, and sing.
Ceru is able to generate or grow minerals and crystals at will. She can grow ferns and other small plants at will.
She can shift her shape to a more monstrous version of herself, or other shapes similar to her normal form.
She can assume the form of a crow. (She is able to fly when she is in her crow form!) When she is a crow, she can have her white throat marking and a white spot behind each eye - or she can appear as a normal crow.
When she is a crow, she can't speak, only bird sounds!
She can also take the form of a doe (blacktail deer).
She can appear in a more anthropomorphic form as well.
She can grow antlers or horns, and remove them at will. The antlers are always black, usually small and forked but can be drawn bigger - growth pattern is like blacktail or mule deer antlers. Horns will be shape of pronghorn antelope.
