Bluebird Azurite is short in stature with four legs. She has dodger blue skin with red and mint-green patches, a singular black eye, and red hair styled in a bowl cut.
At first, Bluebird seems to be a very kind and sweet gem, offering Steven food and hanging out with the gems, even though she was a bit of a prankster. Steven automatically assumes Bluebird is up to no good, and later his assumptions are proved to be true. She seems to be a very cruel gem, holding Greg off of Steven's roof, just so she could get his attention. She later attacks Steven without hesitation, showing how powerful her grudge towards him is.
