Blackagar Boltagon's parents were two of Attilan's top geneticists; Agon, head of the ruling Council of Genetics, and Rynda, director of the Prenatal Care Center. Subjected to the mutagenic Terrigen Mists while still an embryo, he was born with strange powers surpassing the norm of other Inhumans. As an infant, he demonstrated certain energy-manipulation abilities he could not yet control, particularly a sonic force of great destructive potential. To protect the community, he was placed inside a soundproof chamber and forced to wear an energy-harnessing suit until reaching maturity.

A month after being awarded his freedom, Boltagon discovered his younger brother Maximus was conspiring a treacherous pact with emissaries of the alien Kree. Attempting to stop the Kree ship from escaping, he used the forbidden power of his quasi-sonic voice to knock the craft out of the sky. The vessel crashed into Attilan's parliament building, killing several key members of the Council of Genetics - including Boltagon's parents. The reverberations of his shout damaged Maximus brain affected his sanity and suppressing his nascent mental abilities, rendering him powerless. Despite his silent protest, Boltagon was obligated to accept the mantel of leadership of Attilan as the Inhuman sovereign Black Bolt.
