7. Green Lantern: Circle of Fire

Included Titles: Green Lantern: Circle of Fire #1-2 and assorted one-shots.

I miss this style of crossover. One opening chapter issue, a bunch of one shots and then a concluding chapter. They're fun and stand-alone. So in this one, my personal favorite Green Lantern Kyle Rayner panics when the galaxy is menaced by a creature called Oblivion, who looks a lot like something Kyle designed as a kid. Kyle sends out a distress call, which somehow summons a group of Green Lanterns from all across time from other dimensions.

The Justice League vanishes trying to fight Oblivion and the new band of Lanterns team up with the heroes who are left to figure out what's going on. Adam Strange and Green Lightning, a Flash-Lantern from the future go to help Rann after Oblivion passed through. The Atom and the Teen Lanterns, twins who share one ring, check up on some earth villains who might be involved. Firestorm and early Manhunter/Green Lantern prototype G.L. hunt for the possibly mythical Omega Solution. Power Girl and the medieval Emerald Knight search for the Justice League. And Kyle and his alternate universe replacement AKA his dead girlfriend Alex, search for Oblivion's current location. They all come together and save the day in the end, and there's an obvious twist.

Long-term effects: Not too much. This did bring back Martin Stein though, the other half of Firestorm.
