JLA versus Predators
Green Lantern Predator joins his other Metapredators when they go to Earth to kill the JLA. There Green Lantern Predator faces Kyle Rayner in South America and defeats him. Only the quick thinking of the Flash saves Kyle and Martian Manhunter is able to teleport Kyle and the rest of the team back to the Justice League Watchtower.
On the Watchtower the Green Lanten Predator and the rest of the Metapredators show up and fight the JLA. The fight seems onesided again until the JLA switches fighting partners, and starts to get the upper hand. This battle ends when a Metapredotor makes a hole in the Watchtower and the Metapredators are sucked out into space, presumably dead.
