Sean Cassidy aka Banshee is a mutant with the ability of 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.
Banshee's unique sonic blasts carry him into flight. Like other young mutants, Banshee's powers reach their full potential only under Charles Xavier's patient tutelage, and in a battle that will have global consequences.
He makes a brief cameo as a prisoner of William Stryker in his mutant testing facility on Three-Mile Island. He, along with the rest of the incarcerated mutants (Quicksilver, Toad, Emma Frost and Cyclops), escape with the help of Professor X.
