What is Sonic Scream?
Sonic screaming is an ability that usually involves a character's voice being used at dangerous capacities. The sonic scream ability greatly varies from character to character. Most characters are able to switch on and off between their normal voice and sonic scream. Unfortunately, this is not the case for Black Bolt, who has by far the most powerful sonic scream, and could destroy a mountain with barely a whisper. Zauriel's sonic scream actually destroys his throat. Other characters with forms of the sonic scream include Banshee, his daughter Siryn, and Black Canary.
