Fictional character biographies Dr. Joar Mahkent When noted European physicist Dr. Joar Mahkent arrived in America with his latest scientific discovery, spectators at dockside were astonished to witness the luxury liner upon which Mahkent was traveling suddenly frozen solid in Gotham Harbor. Investigating this phenomenon, the original Green Lantern (Alan Scott) was shocked by the sight of Dr. Mahkent shot dead in his stateroom, apparently the victim of Lanky Leeds, a notorious racketeer who was reportedly traveling on the same ship. Thus, when the bizarrely costumed criminal known as the Icicle appeared upon the scene later that same day, wielding a unique weapon capable of instantly freezing solid any moisture in the air, Green Lantern presumed he was actually Lanky Leeds, who had stolen Doctor Mahkent's invention. After several frustrating encounters, Green Lantern ultimately unmasked the Icicle as Joar Mahkent himself, who had, in fact, murdered Lanky Leeds, using his cold ray gun to temporarily disguise Leeds' face as his own. Attempting to escape from Green Lantern, the Icicle leaped off a 20-story building and apparently plunged to his death in the Gotham River far below. Actually, the Icicle survived his fall into the river, and returned to plague the Emerald Gladiator time and time again, eventually becoming a member of the Wizard's second Injustice Society of the World which succeeded in briefly hypnotizing the Justice Society of America.
