GHOST RIDER JOINS THE THUNDERBOLTS! General Ross’s Thunderbolts were brought together to clean up problems no one else could…but what about when the problem is ON the team? The seemingly all-powerful madwoman called Mercy has gone too far, slaughtering innocent people to fulfill her twisted mission of mercy. Who can the team turn to to help take down this powerhouse? How about Johnny Blaze, the original Ghost Rider? Can he save the team before it all goes to hell? Or will he lead them there?
