This one-shot comic book has the Justice League of America battling Predators. The story begins with the JLA saving a shipload of aliens called Dominators, who have been trying to conquer earth several times. But the dominators have modified the Predators-and given them powers that the JLA possess. At one point we think that the Martian Manhunter has been killed, since his head is on a spike, but his brain is in his torso so they're able to re-attach his noggin.
It's been a while since I've read anything about the JLA-and thought it strange I have no recollection of this version of the Green Lantern. Oh well. Anyways, this is an interesting story and a successful mash-up of two different francises.
