Superman: They Saved Luthor's Brain!

In this single-issue DC Comics special from 2000, writer/artist John Byrne delivers a characteristically sharp and inventive Superman story. The premise finds the Man of Steel and his allies facing the bizarre aftermath of Lex Luthor's apparent demise, as the villain's brain is kept alive for a nefarious purpose. It's a clever, self-contained tale that showcases Byrne's knack for blending high-concept sci-fi with the core dynamics of the Superman mythos.
