Powers and AbilitiesEdit


Banshee is a mutant whose superhumanly powerful lungs, throat, and vocal cords could produce a sonic scream for various effects, in concert with limited, reflexive psionic powers which directed his sonic vibrations. He could hover or fly at the speed of sound, and could carry at least one passenger. He could overwhelm listeners with deafening noise, stun them with tight-focus low-frequency sonic blasts, plunge them into a hypnotic trance, disorient them, nauseate them, or simply render them unconscious. Using sonic waves, he could rapidly vibrate himself or other masses at will. He could generate sonic blasts which struck with tremendous concussive force, liquefying or outright disintegrating targets at his highest levels of power. By radiating sound waves outward and reading the feedback, he could locate and analyze unseen objects in a sonar-like fashion. By modulating his scream's harmonics, he could confuse most scanning equipment. He could instinctively analyze, replicate, and block sonic waves or vibrations from other sources.

Banshee generated a psionic field which protected him from the detrimental effects of his sonic vibrations, though his sonic powers could still injure him when pushed beyond safe limits. His physiology seemed fully vulnerable to conventional injury when his sonic powers were not engaged. Banshee had selective hearing, enabling him to focus upon, enhance, or totally block out any given sound in his environment; this shielded him from the deafening sound of his own screams, and made him a superhumanly acute eavesdropper in surveillance situations.
