In "Superboy Meets Steelboy!", Superboy ventures beneath Smallville to aid Queen Luela, stepping in as Steelboy—a robot modeled after himself—when the original is unavailable. Written by Edmond Hamilton and brought to life by Curt Swan’s art with George Klein’s inks, this 1962 adventure blends mystery and heroism in a hidden underground world, where even a hero’s double can have a mission of its own. The cover by Curt Swan and George Klein captures the intrigue of a hero in a role he never expected.
