Aireo, a member of the offshoot of humanity known as the Inhumans, underwent exposure to the Inhuman Terrigen Mists soon after birth, giving him his superhuman powers. Initially, these consisted only of the ability to fly, but over the years his powers increased. Ally of Maximus As an adult, Aireo's flight powers enabled him to take on the prestigious job of perimeter patrolman for Attilan. However, he betrayed those who trusted him and joined the rebel Maximus in the coup and civil war that gave Maximus control of Attilan. After Maximus was defeated, Aireo joined him in exile, supporting Maximus during one of his further attempts to disrupt Black Bolt's rule.[2] Since Maximus's last defeat, Aireo nursed his hatred for the current royal family and avoided any further contact with his fellow Inhumans.
