IDW Publishing made what will certainly be remembered as one of the most surprising and welcome announcements of this year's Comic-Con when the company confirmed that it will produce a crossover comic book starring DC Comics' Legion of Super-Heroes and Gene Roddenberry's classic Star Trek characters. The project, written by Chris Roberson (iZombie, Superman), is a particularly inspired pairing for a crossover, and was met with strong approval from the San Diego crowd.Roberson's Legion of Super-Heroes/Star Trek crossover will be illustrated by Jeffrey and Phillip Moy, who've drawn both properties before, and feature covers by Phil Jimenez. Variants will come courtesy of Gabriel Rodriguez as well as noted Legion artists Mike Grell, Steve Lightle and Keith Giffen.

The story stars the classic versions of the characters, all of whom are beloved by Roberson, who said that he can name the home planet of every Legionnaire.

Six members of the Enterprise crew and six Legionnaires finding themselves trapped in an altered timeline that has somehow replaced both of theirs. The new timeline has blends elements of both, but while the Legion and Starfleet characters come from a bright, hopeful future, this story takes place in a world where humanity "went wrong" and has conquered many alien races. The story will also feature signature villains like the Borg, Klingons and Khunds.

"When Chris [Ryall] first approached me about doing this, I thought it was a prank," Roberson said. "I've been researching for this story since I was nine."
