Superman Forever is a one-shot story published by DC Comics in 1998, serving as a bridge between the Millennium Giants storyline that closed out Superman Red/Superman Blue and The Dominus Effect storyline. As Superman is merged back into one being and has his original powers and abilities restored, he soon finds out that Lex Luthor's infant daughter Lena has been captured. Working together with various people in Metropolis, Superman soon discovers Lena's kidnapper and rescues her, giving her back to Lex.
This comic book story provides examples of:
- Adult Fear: Lex goes ballistic when he finds that his daughter Lena is missing. He also fears the worst when an explosion takes out the Hypersector, but fortunately Superman shields Lena from the explosion.
- Art Shift: Various pencilers and inkers contributed to this story, leading to this throughout the entire issue.
- Continuity Nod: A cruel one for Cat Grant, as the Toyman plays with a doll that plays a message that mocks the fact that he killed her son some years ago.
- Enemy Mine: Superman works with Lex Luthor to get his daughter Lena back, but doesn't give Lena back to Lex without giving him a sound warning.
- Fusion Dance: Superman Red and Superman Blue inexplicably fuse back together into the original Superman with his original powers.
- If I Can't Have You...: The Contessa, who has engineered the kidnapping of Lena, has Bizarro threaten to kill Lena by putting her into a rocket and causing tons of dynamite to explode around her, believing that if she can't have legal custody of the child, then neither can Lex.
- Internal Homage: The beginning of the story mirrors that of Superman's origin of being sent to Earth from Krypton, as the grown-up Kents find Kal-El crash-landing to Earth without his clothes. Bizarro also homages this particular scene in his attempt to "send Lena Luthor up in a rocket" by exploding dynamite around her.
- Last Kiss: Jor-El and Lara share one together as Krypton explodes and Kal-El is rocketed to safety, a scene never shown in The Man of Steel.
