Icicle II (Smallville)

Angered by the Justice Society of America for putting his father, the original Icicle, into a coma, Cameron devoted himself to getting revenge on the retired team of heroes. Luckily for him, the secret organization, Checkmate, was very interested in recruiting his talents and were allowing him to pursue his vengeance at the same time. Icicle ambushed and murdered the Star Spangled Kid who was attempting to contact Chloe Sullivan, the Watchtower for the new generation of heroes. Once he had done that Cameron killed the Sandman next, assassinating him in his own home. He went through a list of the Justice Society, crossing off each one that he killed. His next target was Courtney Whitmore, the protégé of Star Spangled Kid, who had now taken the identity of Stargirl. They engaged in a duel and when Cameron finally got his chance to kill her, he was stopped by the Green Arrow.
