to find Grundy before any of the JSA members are hurt going after him. Minutes later, Grundy arrives at JSA HQ, and, not finding the Lantern there, he smashes the place up, then leaves. Green Lantern and Doiby use a special radio-like device Alan Scott had developed that is attuned to the mental wavelengths of Grundy himself; Green Lantern calculates the path of Grundy and announces over the radio in JSA HQ where Grundy will strike. When Green Lantern and Grundy meet, Grundy rips a tree out by its roots and smashes it into the Lantern. Green Lantern fights back with his power ring and fists until both men fall into a nearby stream and over a small waterfall. The Lantern is severely dazed and tries to ward off Grundy with his ring, but he is much too weak. Grundy grabs Green Lantern by the throat and begins to squeeze the life out of him, holding his head underwater. However, Hawkman strikes Grundy with his mace, and Doctor Mid-Nite revives the Lantern. A combined attack brings down Grundy, and Green Lantern deposits Grundy on a distant, lifeless planet. A battle soon commences when Grundy's body gravitates towards young astronomer Dick Cashmere as he learns to ride light waves, resulting in his assuming Cashmere's identity for a time while leaving the real one bound and gagged, though the Society finds him soon after. In this incarnation, he gains intelligence, which he subsequently loses when Green Lantern defeats and buries Grundy in 1947. At this point, Grundy is freed and enlisted along with several other supervillains by the time-traveling criminal Per Degaton in his second appearance, who has traveled to 1941 to capture the Justice Society of America on the day of the attack on Pearl Harbor, hoping to change history and take over the world. Grundy encounters Green Lantern, Flash, and Wonder Woman in Echo Park, whom Grundy knows from 1947. Grundy bests the costumed trio, and is summoned by a mysterious voice to deliver them or "pay the penalty". The All-Star Squadron comes to their rescue, Sir Justin faces off against Solomon Grundy and Grundy is the last villain to be transported back. He is thrust back to the moon, where he remains for over two decades, as this timeline is erased once Degaton is defeated. After many years, Grundy is knocked loose from his planet prison and returns to
