Kurt Busiek's Astro City

Astro City is a well-populated urban center somewhere in the western United States, lying largely between two rivers — the Wildenberg, to the west, which flows into the larger Gaines River, to the east and south. To the north lies the bulk of Mount Kirby, while to the south, in mid-river, is the Biro Island Correctional Facility.

Until the close of World War II, the city was named Romeyn Falls, but after suffering widespread destruction, it was rebuilt and officially renamed in 1947.

Jack-In-The-Box — an athletic urban hero who uses clown-based gimmicks, including his "handsprings," "footapults," entangling confetti and electro-shock rubber noses in his crusade against crime. The first Jack-In-The-Box, debuting in 1964, was Jack Johnson, a toy designer who created the identity after learning that his toy designs were being used as weapons. The second Jack-In-The-Box was his son, Zachary Johnson, who owns and runs a successful toy company himself. The current Jack-In-The-Box, Roscoe James, is Zachary's protegee and trainee.
