Category:Sean Cassiby - Banshee

Sean Cassidy was a young rich mutant with undiscovered powers. His parents died, leaving him and his cousin Black Tom Cassidy with a huge fortune and the castle they had grown up in, called Cassidy Keep, although as Sean was the rightful heir, he gained all of it. The castle was a strange place, where leprechauns lived under the protection of the Cassidy Family. Both Sean and Black Tom were mutants; Sean's power was a sonic scream.
