Blackagar Boltagon, also known as Black Bolt, was the Inhuman King and a member of the Illuminati. Alongside his team, Black Bolt helped kill Thanos on Titan, and was forced to execute Stephen Strange, as he still posed a threat to the Multiverse due to his prior use of the Darkhold. Black Bolt and the Illuminati gathered to hear the case of Doctor Strange from Earth-616, though their proceedings were interrupted by Scarlet Witch, dreamwalking in her alternate self's body. Black Bolt's mouth was removed by Scarlet Witch, causing him to internally panic and accidentally kill himself by imploding his head with his own muffled sonic scream.
