"The Wail of the Banshee!"
Professor X tries to test Cerebro and the mental modifications he made to the Mimic, but his work is interrupted as Cerebro detects a new mutant terrifying the city. Before the X-Men can start to track him down, the Banshee and his accomplice, the Ogre, come to kidnap Professor X. Their plan is foiled by the X-Men, and the Banshee is captured. While the team awaits the return of the Ogre, the team discovers that the Banshee is not the super villain they were led to believe; he was being controlled by the Ogre and Factor Three.
