Imaginaries, Volume 1: Lost and Found — Mike S. Miller

What happens to those imaginary friends, childhood superheroes, playmates and stuffed animals we all gave life to as children when we grow up and don't need them any more? They go to the Imagined Nation. Join Superhero G as he explores this strange new world, full of the imaginings of billions of children around the world. Follow him as he meets strange and wonderful characters, the kind only a child could believe in, and discovers a new purpose for his existence unbound by the imaginings of his creator, and free to become more than even he has ever imagined before.
