This list covers most of the heroes in the Astro City series. I know there are more, but these are the only ones I could find on Comicvine.
WHAT IS ASTRO CITY?
''Welcome to Astro City, a shining city on a hill where super-heroes patrol the skies. Each chapter in this collection is a standalone story, highlighting different aspects or characters in the Astro City world. The city's leading super-hero tries to be everywhere at once, and berates himself for every wasted second as he longs for just a moment of his own. A smalltime hood learns a hero's secret identity, and tries to figure out how to profit from the knowledge. A beat reporter gets some advice from his editor on his first day on the job. A young woman tries to balance the demands of her family with her own hopes and desires. Despite the fantastic settings, the characters in these slice-of-life stories feel like real people, and that gives the stories real power.''
