Written by Dave Gibbons, and illustrated by Ivan Reis, Marc Campos, and John Kalisz, the series concerns a war between the planets Rann and Thanagar, and features Adam Strange, the Green Lantern Corps, Hawkman, Hawkgirl, L.E.G.I.O.N.

Rann-Thanagar War, along with Villains United, The OMAC Project, and Day of Vengeance, is one of four miniseries which lead up to DC Comics' Infinite Crisis event.

In Rann/Thanagar War: Infinite Crisis Special #1, the rift begins endangering the lives of those in the star system by sending out destructive energy waves.

Donna Troy's assembled heroes are working to keep the peace between the two warring forces, when Adam Strange receives a message from Tigorr of the Omega Men.

He leads Strange, along with Hawkman and Hawkgirl, to a stray Thanagarian surveillance satellite, which has documented footage of Superboy-Prime forcing Rann and Thanagar to collide, and thus, go to war.

Kyle gives Jade's body to her father, Alan Scott, and he cradles her in his arms, remarking how she seems herself again, until another energy wave destroys her mortal remains.

There is debate of whether so much power can be wielded by any Lantern, but Kyle's previous experience is considered, and the Guardians agree that being able to monitor him this time is an important difference.

On the barren surface of Thanagar, Adam Strange finds evidence to present to all of the warring groups: handprints deep within an enormous crater, created by Superboy Prime's interference.
