Spoilers ahead for this week's Hal Jordan & The Green Lantern Corps #18.
Rip Hunter has returned to the DC Universe, bringing a mystery along with him, in this week's Hal Jordan & The Green Lantern Corps #18 by Robert Venditti and V. Kenneth Marion.
The time-traveling hero, who is part of the current live action TV show DC's Legends of Tomorrow, hasn't been seen in DC's primary comic book continuity in years. He was seemingly erased from existence after Flashpoint, although events in Convergence indicated that he - or a version of him - survived the reboot.
Before the "New 52" reboot, Rip Hunter was a recurring time-traveling character who witnessed the return of DC's multiverse in 52 and was later revealed to actually be Booster Gold's son from the future.
Green Lantern Mystery
Rip's appearance came at the end of Hal Jordan and the Green Lantern Corps #18, which also featured Kyle Rayner rejoining the Green Lanterns in name and uniform, Saint Walker beginning his journey to rebuild the Blue Lantern Corps, and a new enemy attacking.
It also continued the new status quo of the Green Lanterns and Yellow Sinestro Corps Lanterns working together to police the universe - there is now one Green Lantern and one Yellow Lantern per sector.
As the issue begins, one green/yellow duo is patrolling together - Gorin-Sunn and the Sinestro Corps member known as "Space Ape" - and they're told (by the Green Lantern ring) that a nearby planet is experiencing a "violation of Universal Criminal Code Statue 3648.1," which apparently refers to the presence of a time anomaly. When they arrive, the anomaly is gone, but they notice that the planet has veins running through the rock that are filled with "ultra-dense will," the energy that powers the Corps' rings.
When they come upon a mysterious cave that's surrounded by these veins, they're attacked.
Meanwhile, back on Mogo (which is the headquarters of the Green Lantern Corps and the Sinestro Corps), Kyle Rayner is a Green Lantern.
(To review, Kyle was a White Lantern, but he lost the ability to command the seven lights of the emotional spectrum in Hal Jordan & The Green Lantern Corps #17. He and Saint Walker were trying to resurrect the Blue Lantern Corps, but there was some sort of unseen "intruder" blocking them - perhaps Mr. Oz, who was shown watching the scene, or maybe someone else. The result was Kyle's return to being "just" a Green Lantern.)
John Stewart leads the Green Lanterns and Soranik Natu now leads her father's Sinestro Corps. And the two have made peace, deciding to work on the same side. (And worth noting, former lovers Soranik and Kyle seem to be on good terms - might the exes get back together?)
Kyle, Hal, and John start to chit-chat about how weird it is to have the Yellow Lanterns around on Mogo, but John compares the alliance to the relationship between Germany, Japan, and the United States after World War II.
But tensions are high, and a group of Sinestro Corps members start to tussle with some Green Lanterns. John, Hal, and Kyle try to break it up, but it only stops when Guy Gardner shows up with Arkillo. Both Guy and Arkillo warn the two corps to work together or else.
Elsewhere on Mogo, the two married Guardians Ganthet and Sayd encourage Saint Walker to journey around the universe to find new Blue Lanterns. But as he leaves, the two Guardians agree that "forces powerful and unknown are intervening."
Finally, someone notices that Space Ape and Gorin-Sunn are missing. Salaak shows Hal and John their last known location, a planet he says has "no life, no record of incidents or activity."
"Wait…" Hal says, looking at a 3-D rendering of the planet. "I know this place."
The Green Lantern computer suddenly announces that there's another temporal anomaly, but this one's right in front of them, on Mogo.
The anomaly goes all bright-white-light, and a figure emerges from it. It's a human man.
"My name is Rip Hunter," the man says. "The Green Lantern Corps has been erased from the future."
Rip Hunter collapses, and as the Green Lanterns rush to get him medical attention, Hal notices he is wearing a Green Lantern ring.
Hal Jordan & The Green Lantern Corps #19 is scheduled to hit shelves April 26.
