This is the final Showcase try-out for Adam Strange. His feature continues in the first story of Mystery in Space #53.

Synopsis:
Adam Strange returns to Rann via Zeta-Beam, but this time no menace awaits him. Alanna gives him a tour of the planet, where he is awarded several treasures for his past service to Rann. Adam discovers the treasures are phony, arousing his suspicion.

The treasures were altered by Zakkad, an energy-being from Ekelon. Zakkad uses a magnetic meteor to bring Adam to Ekelon. Zakkad orders Adam to tell him the secret of teleportation. Fearing Zakkad will use the information to conquer the universe, Adam double-crosses the energy-being. While he distracts Zakkad, Alanna uses the magnetic meteor to send the alien and his world into deep space.
