More than their tools and their methods separate them from the rest of the earth's heroes. There is something that burns fiercely inside them. Now fate and the machinations of Blackheart, an insane villain bent on assassination, has brought them together. Seeking allies to aid his plans, Blackheart hopes to reach into the deepest parts of these heroes, into their very hearts and souls. However, what he finds may be more than he bargained for. Discovering that in these heroes there lie "Hearts of Darkness". Each are 5" tall.
