Using the super-advanced computer the Eternity Brain to control the flow of time for his next bid of conquest, though he realises this will stop time and thus destroy the universe as it cannot be halted, and he cannot revoke orders he has given, the Time Lord orders the Eternity Brain to pluck Jonah Hex, Miss Liberty, the Black Pirate, Enemy Ace and the Viking Prince from their respective eras and gives them power enhancements to battle the JLA and the JSA during their annual meeting, hoping they can stop the device by being lured to his castle. The two teams are beaten in the first battle by the empowered heroes, who are then transported to the Lord of Time's base, a castle in a different dimensional space around the year 3786. A group of them track this trace to the Lord of Time's castle using the Cosmic Treadmill after detecting the trace that leads to the Lord of Time's year. The other heroes had already been defeated and imprisoned. The Brain uses its defences to summon beings from different times to battle them. With seconds to spare the Elongated Man, who was able to contort himself enough to get through the laser grid protecting the castle, destroys the Eternity Brain.
