Quasi-Sonic Scream: Initially, Ahura possessed a hypersonic scream,and although he did not demonstrate this ability since infancy, he is still immune to his father's sonic powers.
Energy Beams: He could generate destructive energy blasts from his eyes.
Force Field Generation: He could project protective energy shields around himself and others.
Flight: Ahura could mentally manipulate and harness the unknown particles his brain generates to interact with electrons to create anti-gravitons that enable him to defy gravity

His existence seems overlooked in the Son of M series: Crystal demands the Inhumans go to Earth and retrieve her daughter, Luna. Medusa and Black Bolt refuse to intervene, to which Crystal bitterly retorts they would understand if they had children. Medusa then looks upon Crystal silently with contempt.
This apparent error was partially walked back in the follow-up series Silent War, which revealed Ahura had succumbed to madness and been placed in a royal asylum, after which Black Bolt decreed no one could ever speak of his son again. If intended, that makes Crystal's comment seem even more hateful, forcing Medusa to openly ignore her son's existence or else violate a royal decree.
In Uncanny Inhumans #5, Ahura states himself to be sixteen years old.
