Star Trek / Green Lantern #3

Synopsis

Hal tells Kirk of the Lanterns final battle with Nekron, which led to Ganthet escaping to this universe and causing the surviving Lanterns to be transported as well. While the Chekov, Uhura, and McCoy adjust to their rings, the other rings are put to more diabolical uses. On Gornar, Glocon uses the red ring to kill his father and assume control of the Gorn Hegemony, but is confronted by Atrocitus. On Romulus, Decius uses the orange ring to kill the senate to become the new leader, and encounters Larfleeze. On Qo'nos, Sinestro agrees to help Chang destroy the enemies of the Klingon Empire.
