"The Pluto Syndrome"
Superman finds himself trapped on Earth-C and the only way he can escape is with the help of Captain Carrot and Earth-C's greatest heroes. It's too bad that an Earth-1 villian lurks in the shadows waiting for his chance to prevent the escape.
(**Readers Notes** In the early 1980's Wonder Woman's alter ego was still Diana Prince. A JLA flashback in this issue indicates the Superman is Kal-El)
