Blackagar Boltagon, otherwise known as Black Bolt is the King of the Inhumans, stands as one of the most powerful heroes in Marvel Comics. He is the product of Agon, who was a top geneticist, and Rynda. While Rynda was pregnant with Black Bolt, Agon exposed her to the Terrigen Mist as an experiment. Bolt was born with powers miles beyond that of the average Inhuman. Because of the uncontrollable nature of his powers, he spent 19 years of his life in an energy dampening chamber training to control them.
Bolt has the ability to harness electrons and the speech center within his brain has a unique organic mechanism: it can create an unknown particle that interacts with the electrons he harnesses to create phenomena that are determined by his mental control. One of the main abilities that Black Bolt gains from that is his Quasi-Sonic scream. A whisper from him can level a city and if he was to shout at full power he could destroy an entire planet. Because of that ability, Bolt has gone through extreme mental training to never utter a sound even in his sleep. He wears a tuning fork on his forehead that allows him to focus his scream on a single target whenever necessary. Black Bolt also brings to the table his superhuman physiology, the ability to fly using the particles he can generate, and exceptional hand to hand combat.
