Variant release featuring blue and yellow costume.
One look at his dossier will show why Sean Cassidy was chosen as new headmaster at Xavier's School for Gifted Youngsters. His mutant power -- a devastating sonic scream -- earned him the code-name Banshee, and a long-standing place with the X-Men. A former Interpol agent, and father of a mutant daughter, Cassidy has what it takes to transform this inexperienced group of teenagers into the highly-trained team called Generation X.
