Solomon Grundy All-American Comics #61 (October 1944) Formerly Cyrus Gold, a Gotham City merchant murdered and thrown into Slaughter Swamp, where he was transformed into an undead, superstrong zombie-like creature, the wood in his body giving him resistance to Green Lanturn's ring. He stumbled into a hobo camp and remembered he was 'Born on a Monday', so was named Solomon Grundy by a hobo, and taken on a crime spree by them. He was apparently killed by a train, but later revived by an evil scientist's formula. Grundy was initially an enemy of the Golden Age Green Lantern and the Justice Society, but has both battled and aided various heroes during his multiple resurrections. He has absorbed some of Green Lantern's power due to confrontations with him. Later it is revealed that Cyrus committed suicide. Sportsmaster All-American Comics #85 (May 1947) Lawrence "Crusher" Crock was a former professional athlete who turned to a life of crime using various sports-themed paraphernalia. An enemy of the Golden Age Green Lantern, Sportsmaster later retired and married fellow villain the Tigress. Sky Pirate Green Lantern #27 (August 1947) The Sky Pirate is a pirate-themed villain who battled Alan Scott in the summer of 1947. Nothing is known of his origins or how he had amassed the financing for the expensive equipment he used in his early crimes. His first public crime was recorded when his airship, the Flying Dutchman, anchored alongside the penthouse apartment of a Gotham aristocrat. Casting a nearly invisible net lined with grappling hooks to the side of the building, the Sky Pirate manufactured the illusion of running across the air itself. Harlequin All-American Comics #89 (September 1947) Molly Mayne, secretary of Golden Age Green Lantern Alan Scott, developed a crush on the hero and sought to gain his attention as a costumed criminal. She used hallucinatory goggles provided by the Manhunters, but she was more likely to help Alan and the Justice Society than oppose them. She helped them when they had been given amnesia by the second ISW. Eventually reforming, Molly later married Alan and the two remain together to this day. Icicle All-American Comics #90 (October 1947) Dr. Joar Mahkent, a scientist who created a powerful "ice-gun" capable of freezing the moisture in the air, was a foe of the Golden Age Green Lantern. He originally made it seem a gangster had killed him by killing him and altering his body, but his scheme was foiled by Green Lantern. He was killed by Krona during the Crisis on Infinite Earths and left half his fortune to Flash. His son Cameron Mahkent, born a cryokinetic after exposure to his father's weapon, became the second Icicle. Knodar Green Lantern #28 (October-November 1947) Knodar comes from the year A.D. 2447 on the parallel Earth-2. Everyone's needs and whims are met by machines so that there is no incentive to steal, therefore no reason to create crime or criminals. The one person who liked this idea of being a criminal was Knodar. He was inspired from old gangster movies. In his initial try at being a criminal he was caught and placed in a cell for all to see as a social anomaly. His uniform was custom, since no uniforms needed to be mass-produced, with P's stitched on the uniform to stand for prisoner. He escaped to 1947 and began a crime spree with stolen tech from his time period. "Made of Wood" Killer Detective Comics #786 (November 2003) Samuel Sullivan was an Irish immigrant in the early 20th century, instantly embracing the United States as the land of opportunity. He witnessed the Sportsmaster defeat Green Lantern with a wooden baseball bat and lost all faith when Sportsmaster destroyed Sullivan's store. Sullivan was so devastated that he murdered the mayor (who had given Gothamites "false hopes") with the bat, carved "Made of Wood" into his chest, and placed his corpse in front of Alan Scott's statue that the mayor had erected for him. This was established as his modus operandi, the first in a long string of murders, which ended abruptly when Sullivan was committed to Arkham Asylum in December 1948. His son was an Irish mobster who was mocked by his fellow mobsters. When Seamus died, his only possession, a small chest of drawers, went to his grandson Francis Sullivan. Francis discovered his grandfather's notebook and took up the mantle of the "Made of Wood" Killer. He was defeated by Scott, along with Batman and Jim Gordon. Red Lantern The New Golden Age #1 (November 2022) In the series "The New Golden Age", Green Lantern had an enemy known as Red Lantern. Vladimir Sokov was a Russian soldier for the Soviet Union's Red Army who became their answer for Green Lantern after the Russian scientists managed to harness the powers of the Crimson Flame. As Green Lantern and Red Lantern have fought on occasions during the 1940s, they have worked together when Nazis threatened both their countries.
