Wave is a striking, tall, and exceptionally voluptuous anthropomorphic swallow covered in vibrant purple feathers. She possesses a highly defined and athletic build, sporting muscular arms and a toned six-pack midriff that balances her soft, heavily flared, and exaggeratedly curved lower body. Her sharp blue eyes are framed by thick, double eyelashes and light purple eyelids, set alongside a distinct, golden-curved beak.
