Dr. Joar Mahkent
Joar Mahkent is a European physicist who travels to the United States to showcase his latest discovery. Upon his arrival, Mahkent's ship is suddenly frozen solid in the Gotham City harbor. After investigating, Green Lantern (Alan Scott) learns that Mahkent has been shot dead while on the ship, apparently the victim of racketeer Lanky Leeds. When the criminal Icicle appears wielding Mahkent's invention, a weapon capable of instantly freezing moisture, Scott assumes him to be Leeds. Scott unmasks Icicle as Mahkent, who had killed Leeds and disguised Leeds' face as his own. While attempting to escape from Scott, Mahkent leaps off a 20-story building and apparently plunges to his death in a river. [3]
Icicle survives his fall into the river and returns to battle Green Lantern, eventually joining the Wizard's second Injustice Society. He is a founding member of the Crime Champions, along with Wizard and Fiddler, who allied with a trio of criminals from Earth-One.
During the Crisis on Infinite Earths event, Icicle is killed while attempting to attack Krona's laboratory. [4]
Cameron Mahkent
Cameron Mahkent is the son of Joar Mahkent. His father's prolonged exposure to the weapon altered his genetics, causing him to be born a metahuman with innate power over ice. Cameron's skin pigmentation was also affected, making him appear to be albino. [5]
Cameron became the second Icicle shortly before joining the Wizard's Injustice Unlimited. The group overcomes the security at the International Trade Conference in Calgary, with Icicle being tasked with retrieving Solomon Grundy. He successfully retrieves Grundy and takes a hypnotized Icemaiden and Jade to the Arctic Circle. Injustice Unlimited's plan of blackmailing businessmen is interrupted when Hourman (Rick Tyler) frees himself. In the ensuing battle, Cameron escapes. [6]
Weeks later, Injustice Unlimited plots to murder the members of Infinity, Inc. to make a name for themselves. Icicle goes after Brainwave Jr. After believing the mental mutant dead, the Icicle returned to his cohorts. A plan was hatched to bring all the remaining Infinitors to Stellar Studios and kill them, a plan defeated only by the unwillingness of Hazard to cooperate and the sudden reappearance of Brainwave and Jade. Icicle nearly kills Brainwave in hand-to-hand combat, but is knocked out by Jade. [7]
In 2011, The New 52 rebooted DC's continuity. The Green Team encounter Icicle on a meteor which he hijacked from businessman Bellachek Temple to give to his client. Icicle attacks the Green Team, but relents after the meteor is destroyed. [8] It is later revealed that Icicle and Temple are in a relationship. [9]
In 2016, DC Comics implemented a relaunch called "DC Rebirth", which restored its continuity to a form much as it was prior to The New 52. Icicle appears at a villain award show at the Hall of Doom that is hosted by Harley Quinn. [10]
In "The New Golden Age", Icicle appears as an inmate at Belle Reve Penitentiary before being recruited into the Justice Society of America. [11] [12]
