Upon preventing a cataclysmic rift in their universe, several members of the 30th century's famed champions, the Legion of Super-Heroes, find themselves stranded an inconceivable distance from home, with no devisable method of safe return. Before they can even attempt to return to their galaxy, however, the Legionnaires must first endure the unknowns of a hostile galaxy plagued by the alien Progeny, whose godlike creator deems diverse species impure "variants" subject to eugenic "deletion."

Joined by superstar artist Olivier Coipel (The Mighty Thor), who made his comics debut on the series, Abnett and Lanning strand the future's greatest heroes in an unknown galaxy beset with mysterious cosmic threats for epic sci-fi storytelling at its finest.

He was the original stretchable superhero of the 1940s, and now PLASTIC MAN is back in an all-new, all-zany four-issue miniseries. How zany is it? Take the stretchable power of the really long arm of the law, add to it his amazing ability to assume any shape under the sun, throw in a liberal dose of sidekick Woozy Winks and some of the wackiest bad guys in town, shake it all up with the creative talents of some of the best that comics has to offer-then double that and you'll have some idea of what to expect in the pages of the PLASTIC MAN miniseries. But wacky isn't all you'll find in PLASTIC MAN. There's also slam-bang action, adventure and pathos-all courtesy of writer Phil Foglio, penciller Hilary Barta and inker John Nyberg, not to mention plot and layout assistance from artist Doug Rice, or a series of "reality checks" provided by artist Kevin Nowlan. What's a "reality check"? Well, it's a way of injecting a little bit of the real world into the skewed reality of the realm inhabited by PLASTIC MAN, his friends and foes. PLASTIC MAN-you will believe a man can ply.

Rory Regan was the lucky one. He escaped the mission with his life. Now this battle-scarred war veteran has returned home, hoping to leave the guilt of his fatal raid on an ancient tomb behind him—along with the lives of all the friends and comrades he lost in the process.

Now the souls of the slain are wrapping Rory in supernatural armor, calling on him to avenge their deaths and defend his people from demonic invasion. He is no longer Rory Regan. He is…Ragman. And he'd better get used to it fast, because the war he fought in the Middle East is nothing compared to the apocalypse that awaits Gotham should he fail. He'll need to adapt to the incredible new powers of his awesome Suit of Souls—and figure out who he can trust, be they angel or demon—or nothing will be left but rags and ashes… From the acclaimed creative team of Ray Fawkes (Justice League Dark) and Inaki Miranda (Catwoman) comes a bold new reimagining of one of DC Comics' greatest cult heroes that bridges war, horror, fantasy, and the world of the superhero: Ragman!
