Joar Mahkent is the Icicle, a scientist with a freezing gun who was a regular foe of the original Green Lantern and member of the Injustice Society of the World.


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 Dr. Mahkent's invention.

Green Lantern

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 Leed's 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.

Injustice Society of the World & Crime Champions

Actually, the Icicle survived his fall into the river, and returned to plague the Emerald Gladiator time and again, eventually becoming a member of the Wizard's second Injustice Society of the World and, later a founding member of the Crime Champions of Two Earths.


The Icicle met his death during the Crisis on Infinite Earths, when he and several other super-villains attempted to invade the laboratory of the renegade Oan Krona.


After his death, Mankhent found himself in some sort of Limbo. When S.T.A.R. Labs opened a portal to this dimension, Icicle joined forces with several other villains to escape back to the world of the living, but Titans West foiled their plans. Icicle himself repented of his evil ways and helped the heroes overcome the other villains, earning himself a chance at redemption. Mankhent departed into Limbo's mountains in search of Heaven, finally at peace.[1]

Years later, Icicle's body was reanimated as a soulless undead member of the Black Lantern Corps along with other dead villains.[2]



  • Anti-Freeze Tunic: Joar wore a special insulated tunic, which protected him from the effects of his own Cold Ray gun. This suit saved his life when he fell into an icy Gotham City river.


  • Cold Ray Gun: The Icicle wielded a specially designed cold gun that could instantly freeze molecules of moisture in the air, transforming it into a sheen of ice. The Cold Gun could also freeze living tissue by solidifying the moisture inside of a person's body.

  • Although this character was originally introduced during DC's Earth-Two era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and no longer apply.
