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, Jay Garrick, Hawkman, 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.[16]
