Earth to battle Green Lantern, Hourman, and Doctor Fate. At this point, he has temporary mastery over all wooden objects. Solomon Grundy is imprisoned orbiting the Earth in a stronger bubble created by the combined powers of Green Lantern and Doctor Fate. Grundy was once pulled to Earth-One and substituted for the superstrong Blockbuster due to a machine that was accidentally pulling the Earths together in warp-space and substituting people. During this event, he had absorbed some of Doctor Fate's magic, is stronger than before, and is even able to telekinetically lift Flash into the air. He hates Green Lantern so much he thinks everyone he sees is Green Lantern. He is imprisoned inside a mountain by Earth-One Green Lantern after being lifted up by Earth-One Hawkman and dazed by blows from all the heroes, but when the machine is turned off he is substituted for Blockbuster on Earth-Two and renews the attack, defeating numerous heroes. However, the JSA and JLA went to battle an Anti-Matter being that was threatening both Earths in Warp-Space after being summoned by Doctor Fate, who had sensed the threat due to the Spectre. As the heroes return, they find Green Lantern had placed Grundy and Blockbuster together to occupy them, and the two have knocked the hate out of each other. Grundy is then taken back to his Earth by the Justice Society. In his next appearance, Solomon Grundy battles the combined might of both the Justice Society, and later their counterparts the Justice League, nearly to a standstill at Slaughter Swamp, when he develops an affection for a lost alien child who has accidentally been sent to Earth-2 and is dying due to separation from his pet. Having absorbed magic from Doctor Fate and Green Lantern, Grundy is easily able to defeat the combined might of Superman, Flash, Earth-Two Hawkman, Earth-One Hawkman, and Green Lantern, until he is defeated by both Green Lanterns and sealed in Slaughter Swamp. The alien child is finally reunited with his pet and sent back to his own dimension. While imprisoned, Grundy incorrectly deduces that the second Green Lantern's Earth must contain a second Solomon Grundy and crosses over from his Slaughter Swamp prison on Earth-Two to Earth-One where he overpowers that Earth's Superman before being tricked and stranded on the moon. Solomon Grundy briefly works with the Injustice Society when the Fiddler retrieves Grundy from the moon
