Cheiros

Cheiros was a bat-winged member of the Bird People. When Kylus declared a secession of all winged Inhumans from Attilan, Cheiros was one of the few winged Inhumans to oppose him. In retaliation, Kylus had all winged Inhumans who did not have white feathered wings slaughtered, including Cheiros.

Powers
Aerial Adaptation: The entire anatomy of Cheiros is naturally adapted to flying. His bones are hollow like those of a bird, making him weigh far less than usual for a human. His body is virtually devoid of fat and possesses greater proportionate muscle mass than an ordinary human does. His eyes are especially adapted to withstanding high-speed winds which would hurt the average human eye. He also possesses a special membrane in his respiratory system, enabling him to extract oxygen from the air at high velocities and altitudes.
 * Flight: Cheiros possesses the superhuman ability to fly by means of natural wings, which are much like those of a bat's.
