He was taken by the Council and sent to Earth, but his spacecraft crashed and he was taken in by a childless couple and named "Pope". He grew unnaturally quickly and it was in this period that his "evil eye" power replaced his vocal powers. After his rescue by Gorgon and Karnak, he was taken by the Genetic Council for the leader's own purposes. With the help of his family, Ahura was able to overcome the corrupt Chief Justice who had been stealing his power.
Ahura was locked away for years because he was afflicted with the same madness as his uncle, Maximus. As his powers grew, so did his insanity. The Genetic Council of Attilan deemed him too dangerous and he was taken to the Pacifiers to suppress his powers. They were unable to treat his mental illness. Black Bolt forbid Medusa to see him, however she visited him twice. The first time, Ahura chastised her for allowing this to happen to him. On Medusa's second visit, it was discovered that years with the Pacifiers had taken away Ahura's anger and violence, but left him in an over-sedated state. Medusa asked permission of Black Bolt to use their niece, Luna, to attempt to heal his mind, but Black Bolt flatly refused.
He was later captured along with Black Bolt by the Skrulls, but escaped unharmed with help from the rest of the Inhumans.
When Attilan was stormed by Thanos as he was looking for his secret son hidden on Earth, Black Bolt evacuated its inhabitants by using Eldrac. After Attilan fell, the Inhumans scattered were found, except Ahura. He had been teleported to a century into the past, where he had encountered Kang the Conqueror, who took him under his wing.
When Black Bolt managed to find Ahura, he submitted him to Terrigenesis, and made a deal with Kang to take his son to the timestream, so in case the universe died as a consequence of the Incursions, Ahura could live. Kang accepted, with the condition that even if the Multiverse was somehow saved, Ahura will be his forever.
Evil Eye: Later, Ahura's power has evolved into a psionic "evil eye" which can instantly kill any creature he stares at.
Telepathy & Empathy: Even while still in utero he already was able to sense surrounding area. Ahura is capable to read minds of other people as well as animals and is able to sense the presence or approach of other Inhumans, and even determine their intentions. It is unclear whether he could sense other superhumans or normal people.
Mind Control: Ahura can control the thoughts and actions of others and was able to do it even while still in utero.
Astral Vision: He can see the astral projections of other people.
Enhanced Intelligence & Memory: Even as a child he was very intelligent and was able to recall the events from the first minutes of his birth.
Power Absorption: Ahura can't be completely stripped of his powers, because he can siphon them back. He also can absorb powers of his father. It is unknown whether he can do it with others.
Recently he went through Terrigenesis but his new powers are for now unknown.
He has an unstable mind.
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 placed in a royal asylum, after which Black Bolt decreed no one could even 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.
