Running a universe is no easy feat. When it comes to comics, entire companies make their bones by keeping a fairly consistent group of heroes, villains and everything in between on the rails. Others, however, are run by just a few individuals. Writer Robert Kirkman has developed several of his own universes over the years, spending a good deal of time building up what's been dubbed the Kirkmanverse, a place populated byInvincible, the Global Guardians, the Astounding Wolf-Man, Brit and his other creations at Image Comics via his Skybound imprint.

With a variety of projects on his plate including writing the all-ages "Super Dinosaur", overseeing "Thief of Thieves" and, of course, penning "The Walking Dead" comic book as well as working on the TV show, it stands to reason that Kirkman can't give every character the spotlight. To remedy this, last year Kirkman enlisted writer Phil Hester ("Firebreather," "The Bionic Man") to pick up the ball that is the Kirkmanverse and run with it in "Guarding the Globe" alongside artist Todd Nauck ("Young Justice"). The duo will get another shot at expanding that world on April 3 in the pages of the new "Invincible Universe" ongoing series.
