Black Bolt was born to 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 Mist while still an embryo, Bolt was born with strange powers surpassing even the Inhumans’ norm. As an infant, he demonstrated certain energy-manipulative abilities which he could not yet control, particularly that of producing quasi-sonic energy of great destructive potential. To protect the community, he was placed inside a sound-proofed chamber and given an energy-harnessing suit. There he was schooled in the art of controlling his powers until the age of nineteen, when he was permitted to enter society.
