A fictitious superhero who appears in American comic books published by Marvel Comics is called Black Bolt (Blackagar Boltagon). The character was created by Stan Lee and Jack Kirby, and it debuted in Fantastic Four #45 (December 1965). As the leader of Attilan, Black Bolt belongs to the Inhumans, a secretive species of superhumans with genetic modifications. Due to a connection between his speech center and his ability to harness electrons, Black Bolt’s signature power is his voice. Speaking sets off a tremendous disruption that can completely destroy a city in the shape of a shockwave.. Due to the extreme danger posed by this power, the character has undergone rigorous mental training to prevent himself from uttering a sound, even in his sleep, and he usually remains completely silent and speaks through sign language or via a spokesperson. Since his debut, Black Bolt has been labelled as one of Marvel’s most notable heroes and one of the most powerful members of the Inhumans.

The character of Black Bolt has featured in other Marvel-endorsed products such as arcade and video games, animated television series, and merchandise such as trading cards. Black Bolt made his Marvel Cinematic Universe (MCU) debut in the 2017 Marvel Television series Inhumans, portrayed by Anson Mount, who reprised the role as a variant version in the 2022 film Doctor Strange in the Multiverse of Madness.
