The "Rebirth" era of DC Comics starts in late May with the "DC Universe: Rebirth" one-shot, written by Geoff Johns and illustrated by Gary Frank, Ivan Reis, Ethan Van Sciver and Phil Jimenez. In the "DC Comics Previews" magazine available at retailers on Wednesday, April 13, Johns teases a few major events in the one-shot, as previewed on DC Comics' website.

Though some of this has been previously revealed, this makes it clear that readers should expect one death -- a "mysterious" death, at that -- along with three characters reintroduced into the DC Universe, "with the promise of more." It's worth noting that it's already been established that Ted Kord will return to the DCU as part of the upcoming "Blue Beetle" series, though whether or not he counts as one of the three reintroductions remains to be seen.

More ambiguous (but still intriguing), the issue will also contain "a secret that dives into the very nature of why the DC Universe is the way it is." Along that note, the comic will also "introduce the greatest threat" that the DC Universe ever faced, which given the number of Crises the DCU has been through, is a heck of a promise.

As had been teased last month at WonderCon, the "Rebirth" one-shot will also see Batman set on a new path due to learning the Joker's purported real name in the pages of "Justice League" -- said to be a "a mystery that will change everything he knows about his greatest villain." A cliffhanger from "Aquaman" #25, another Johns-written book (his last on that series), will also be touched upon.

The DC Previews magazine also lays out the structure of the "Rebirth" one-shot: A first chapter on "loss," followed by four alliterative chapters on "legacy," "love" and "life" -- "both the end and beginning of life," according to Johns.

"DC Universe: Rebirth" is scheduled for release on May 25.
