Samaritan is a fictional character in the comic book series Astro City. Created by writer Kurt Busiek and artists Brent Anderson and Alex Ross, Samaritan is the premier superhero of the world, much in the vein of Superman and Captain Marvel. Despite his powers, however, the mind of the man called Samaritan is that of a weary and worn time-traveler with little time to himself and no future to return to.
