Black Bolt's Terrigen-mutated physique surpasses the superhuman physique of typical Inhumans: his strength, stamina, durability and reflexes are all well above typical Inhuman or human levels. His speed and agility are also highly enhanced. An organic mechanism in his brain's speech center produces an unknown particle that interacts with ambient electrons, enabling him to produce certain mentally-controlled phenomena. The most devastating of the effects is Black Bolt's "quasi-sonic scream". Because his electron-harnessing ability is linked to the speech center of his brain, any attempt to use his vocal cords triggers an uncontrollable disturbance of the particle/electron interaction field. Because of this limitation, Black Bolt must be constantly vigilant of even the softest of utterances lest he destroy anything or anyone in his path. At full strength, his voice has the capability to destroy planets,[107][108] while a whisper can rock a battleship. When Black Bolt was captured and experimented on by the Skrulls, it was shown that his "Sonic Scream" is triggered by, and at least partially dependent on, his emotional state.[109]
The fork-like antenna worn upon his forehead helps Black Bolt control his power. He can channel his powers inward to increase his strength and speed, and can focus it through the focusing tool or his arms as concussive blasts. Black Bolt is capable of channeling all available energy into one devastating punch called his Master Blow, which renders him extremely vulnerable subsequently. By concentrating his electrons into anti-electrons, he can fly at speeds up to 500 mph (800 km/h) for a period of six hours, protected by an anti-graviton field. Black Bolt can create a nearly impenetrable force field by focusing his energy around himself, and can use his electron abilities as extrasensory probes, highly sensitive to electromagnetic phenomena, and he can also jam certain electromagnetic mechanisms. Though exhausting, he can create particle/electron interaction fields solid enough to be traversed upon.
Black Bolt also is at least partially resistant against telepathy and shares a semi-telepathic bond with those of his blood (such as the Inhuman royal family and certain others), as was evident when he was able to resist the mental abilities of his telepathically powerful brother, Maximus, and on different occasions, use his own abilities to overpower and take control of Maximus' mind. One of Black Bolt's main uses for his telepathic ability is to communicate his wishes to his wife, Medusa the Queen, who then acts as his mouthpiece to the rest of his subjects. He can also use this limited telepathy to communicate his destination wishes to the royal family's teleporting dog, Lockjaw.
