Synopsis:
Adam Strange waits for the Zeta Beam to strike Earth and return him to Rann, but the Beam never comes. Puzzled by its failure to appear, Adam calculates when the next beam is scheduled to strike and takes it to Rann. When he arrives, he meets Alanna, who explains that the first beam was intercepted by a planet with an erratic orbit. A creature from that planet was brought to Rann, Zaradak. Zaradak, a giant dinosaur-like beast, has been causing damage on Rann ever since.

Adam attempts to stop the creature with his ray-gun, but the creature absorbs and reflects the blast. Adam has food brought to the beast, which settles its rampage. It was only hungry.

When an alien attack force arrives, Adam plans to use the creature to deflect their bombs, but the Zeta energy in the creature returns it to its native world. Adam flies into space to intercept the bomb, destroying with his ray-gun just prior to his own return ride to Earth on the Zeta Beam.
