The Greatest Superman Stories Ever Told #[nn]
In "Superman versus Luthor," Alan Moore and Dave Gibbons deliver a gripping tale where Superman’s birthday celebration at the Fortress of Solitude takes a dark turn when he’s ensnared by the Black Mercy, a mysterious flower from Mongul that traps him in a dream of Krypton’s unexploded past. With Wonder Woman battling Mongul, Batman and Robin race to free Superman—only for the flower to briefly claim Batman before Robin redirects it to its source, trapping Mongul in his own deepest fantasy. The cover by John Byrne and Ken Steacy captures the moment’s intensity, making this a standout entry in the series.
