Dimension Z

Dimension Z

A dimensional reality that is home to the aliens Stix and Hubro. The pair claim to be members of a galactic police force and travel to Earth to take Supergirl back to their home for crimes she committed under another name. After enduring a sham trial with a Superman-imposter testifying against her, Supergirl reluctantly believes that she must have a dual personality and agrees to journey to Dimension Z for punishment (Act No. 327, Aug 1965: "Supergirl...Fugitive from Justice!").

Upon arriving in the alien dimension, Supergirl is told that the accusations were a deception and that she is to compete as a gladiator in a sinister arena of combat. Fortunately, Dimension Z is ruled by a kindly king who eventually returns the Maid of Might to Earth (Act No. 328, Sep 1965: "The Ordeals of Dimension Z!").
