Synopsis:

Having been de-aged by Klarion, the heroes of the JLA, along with Red Tornado and Captain Marvel, are mistaken for Young Justice, and come under attack from the Point Men. However, Anarky unexpectedly comes to their rescue and helps them escape to the JLA Watchtower on the moon.

Unfortunately, the watchtower security system does not recognise the heroes and starts in to attack them - only Batman is able to successfully negotiate all the various traps and enter the defence override code. They then seek help from Shazam, who tells them that he will be unable to undo the chaos on his own, so they head to the justice cave, where they rendezvous with the other heroes, together deciding on a plan of action.
