Slightly different kind of entry this time, in that these fellows aren't really villains. They pop up across the globe and steal various super weapons from various countries and then reappear across the globe, seemingly trying to use said weapons against various cities.
Ok, so far pretty standard villain plot. The twist? They're actually from Earth, just not the Earth the JLA know. Seems they're world and Earth-1 are separated by exactly one minute. A-bombs going off on both worlds have somehow thrown them out of alignment and now they risk sharing the same physical space. Thankfully Green Lantern is able to save the day.
Like I said, interesting. Admittedly, most of the drama could have been spared if someone had taken the time to explain things but for drama's sake I understand. A pity they never showed up again.
