Superman: The Man of Steel #96 (DC, 1999 — Cover A)

The JLA makes a cameo appearance as Superman battles one of his Kryptonian ancestors! You can take the man from Krypton, but you can't take Krypton from the man... nor should the man's wife bring any souvenirs from his Fortress of Solitude, unless they don't mind having their apartment redesigned in the latest Kryptonian decor. Clark must prove his humanity against an ancestor who wants to remake his world. Plus: the JLA helps explain the "Mrs. Superman" fiasco and Steel provides the SCU with new weaponry.
