Professor X uses his telepathy to disarm the headband and remove it, allowing Banshee to help the X-Men defeat Factor Three.
[7] While on the run from the Secret Empire, he fights Captain America and the Falcon, mistaking their then-fugitive status for a link to his pursuers.
Banshee accompanies the team on many different missions and is present for several key moments in the X-Men's history, including the first death of an X-Man, Thunderbird.
[30] Following the Apocalypse Twins' defeat, Banshee is in the X-Men's custody and placed in the medical bay of Avengers Mansion.

He could overwhelm listeners with deafening noise, stun them with tight-focus low-frequency sonic blasts (effective even against shielded ears by penetrating the skull via bone conduction), plunge them into a hypnotic trance, disorient them, nauseate them, or simply render them unconscious.
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 can locate and analyze unseen objects in a sonar-like fashion.
An effective educator, organizer, and lobbyist, he is also an avid American country music aficionado and skillful amateur piano player.
