Kajiu:
Name: Avarion
Age: 20-ish in human age
Gender: Female
Personality: She is aloof, capricious, and assertive. She is not the kind of kaiju that take charge, but she gets along with other kaijus well as long as there's a clear pecking order. She gets very combative when she is treated unfairly or when she can't get something that she thinks she deserves.
Description: She has four purple eyes that look like they belong to a predatory bird, but her massive white body is more like a wolf's, except that her pelt is more feathery. She has bisque crystalline antlers that extend backward instead of sideways. Her claws are also bisque, but they are not crystalline like her antlers. She has two sets of white wings, and she has a tail of an eagle.
Skills: Her eyesight is much sharper than any native creatures on Earth, and her flying speed is remarkable. She is capable of pulling off several acrobatic maneuvers both in and out of combat.
Powers: She can breathe purple flames with her mouth, and she can momentarily harden her feathers to be as sharp as steel. Other than that, she seems to have no supernatural powers.
Motive: She likes hunting down humans that tries to challenge her, chasing them to the end of the Earth. She also likes to collect anything that she deems valuable, whether it is a piece of a building or a broken piece of a stealth jet.
Disguise: She can disguise as a human. When in human form, she has long, straight blond hair, white skin, and purple eyes. She is still prone to taking (smaller) things that she likes even in human form. Her human speech is imperfect, so she tends to stay silent when she is disguised as a human.
History: Up until recently, she was happy in her own strip of land she proclaimed as her territory. She lived an idyllic life, building up her hordes and leisurely chasing down some rude humans who dared challenge her in her domain. However, she was beaten out of her territory by another kaiju, and she was forced to flee with her broken pride. Now she is wandering around this world, looking for another place she could call home. Rumor has it that she is still searching for that perfect territory, wreaking the cities that happens to be in her way as she picks up various treasures here and there...
