Detailed Information of Superhero
Ahura Boltagon (Earth-9997)
The son of Black Bolt and Medusa, Ahura was born a prince of the Inhuman Royal Family. The Inhuman Ruling Council deemed the young boy a threat, fearing his powers would be much like his father's and as a result put the entire Inhuman Nation at risk of destruction. In order to spare their son's life, Black Bolt put his son under the care of Captain Britain to raise as his own son.
At some point in the convening years, the Inhumans grew restless in their refuge and sought to live in the outside world. Not wanting his people to die from the outside world's pollution or persecution, Black Bolt secretly released the Terrigen Mist into the Earth's atmosphere with a device built by his mad brother Maximus. After this the Inhuman Royal Family left Earth to explore outer space.
Superhero Details
His powers are similar to that of his father, Black Bolt, in that he has a quasi-sonic scream. In essence, Black Knight can cause destruction with his voice. The actual strength of this power is unknown, however his voice was powerful enough to blast through the ground of Sentinel City to free Cable.
The power has been utilized through his own vocal chords and also through the "tuning fork" of his armor as well which allows the Knight more control over his abilities.
