* 1st Appearance "ALIEN-ATOR"

As Superman, Batman, Hawkman, Green Lantern and the Flash wait for the rest of the Justice League to show up for their scheduled meeting, the others soon find themselves trapped outside the base when a barrier appears outside the door that none of them can breach.

Superman and the others soon find themselves transported to the year 25,673 AD where they are attacked by strange devices, however their combined efforts destroy the machine and the alien creatures that that were controlling them would change into humans. Their leader would explain that they had built a time device and pulled out a being called the Alien-Ator from the time stream. This evil creature changed the humans of this time into alien creatures, and that the combined energy of the JLA fighting powered the device they built to reverse the effects of the Alien-Ator.

However, they learn that instead of being destroyed, the Alien-Ator was transported back in time to the year 1965. Traveling there, the JLA is attacked by a bodiless creature. Realizing that since they are in the time stream and everything is ageless, Green Lantern uses his power ring to age himself to create a moment in time, shunting the creature away.

Returning to their own era, the JLA finds that their friends have all been turned into aliens and that their device had been damaged in transit. Forced to fight their comrades, Batman repairs the device and the energy expended in their fight against the alien-JLAers causes the device to reverse the Alien-Ator's manipulations in this time as well. Shunting the creature into the time stream once more, the JLA setup the device so that it keeps the Alien-Ator outside of time where it will not be a threat to anyone.
