Cover calls this duo "THE SUPER-TEAM SUPREME", a name which seems to have failed to catch on.Cover also proudly announces that the issues "special guest star" is the original Green Lantern (Alan Scott).
This is, thus, the first cover in Showcase history to obviously advertise a story set on the then-new Earth 2.
Synopsis: A fiery meteor passes Solomon Grundy's energy globe and allows him to return to Earth. When he lands, he seeks his old foe Green Lantern. Dr. Fate senses Grundy's arrival and goes to investigate. He encounters Grundy in a marshland not far from Rex Tyler's chemical plant. Rex also charges into battle as Hourman.
Somehow the combination of radiation from the swamp, Rex's Miraclo pills, and Dr. Fate's magic neutralize the powers of the heroes. Grundy eludes capture and finally tracks down Green Lantern. He defeats GL, then reforms his old gang. Hourman and Dr. Fate again are handicapped by their own powers, but manage to stop the gang.
The heroes finally track Grundy back to the radioactive swamp. Green Lantern has been transformed by the marshes into a monster resembling Grundy. Dr. Fate's magic cures him, then GL and Fate imprison Grundy in a new energy globe placed in orbit above the Earth.
Notes: This story picks up Grundy continuity from All-Star Comics #33, and is thus an early example of DC firmly linking stories published in the Golden Age with the still-new concept of Earth 2. Grundy's absence from the DCU maxed out at almost 18 years.Likewise, it also advances the personal life of Kent Nelson (Dr. Fate), by reintroducing his girlfriend, Inza Cramer for the first time since More Fun Comics #98. It is revealed here, for the first time, that they have gotten married, so, it's the first appearance of Inza Nelson.
