Aerial Adaptation: Angel's entire anatomy is naturally adapted to flying. His bones are hollow like a birds, making him weigh far less than usual for a man of his build. His body is virtually devoid of fat and possesses greater proportionate muscle mass than an ordinary human does. His eyes are specially adapted to withstand high-speed winds which would hurt the average human eye. He possesses a special membrane in his respiratory system enabling him to extract oxygen from the air at high velocities or altitudes.
