List of Astro City characters
The world of Astro City has numerous heroes and villains in the cast, as well as normal, everyday civilians along with other, stranger entities. It is a rich, well textured array of characters, influenced from a broad spectrum of history, myths, classic literature, and the world of comics itself.
Heroes
- Air Ace - A flying hero active in the wake of World War I; the earliest superhero publicly active in what became Astro City, and so considered its first "real" superhero.
- The All-American — A hero of the 1940s and 1950s who wore stylized football gear; like many golden age heroes, he had no superpowers and based his attire and paraphernalia on a theme. Retired in 1959. Rumored to have been killed by a sniper's bullet during the Korean War.
- Alligator - A young outcast hero active in the 1970s; a monster from the sewers recruited by Bravo to become one of the original members of the Astro City Irregulars in the early to mid-1970s.

- Atomicus - A nuclear-powered being from another world who was active in the 1960s. Left Earth because of his girlfriend's determination to prove his identity.
- Augustus Furst – A brilliant scientist/adventurer active from the 1950s through the present. Brother of Julius Furst and adoptive father of Nick and Natalie. Leader of the First Family.
- Barrier – Australian hero who helped rally other Australian heroes in Canberra against the Enelsians. Only mentioned, not seen.
- Beautie - A powerful android and a current member of the Honor Guard. Beautie was constructed by the brilliant daughter of a supervillain genius but is unable to recall her past. She periodically investigates her origins and visits her creator, who invariably orders her to again forget her origins and depart.
- The Black Badge - An urban hero active from the 1950s until 1972, when he retired and opened the superhero bar Bruiser's, which he currently owns and operates under his civilian name.
- The Black Rapier - A detective-themed hero based in New Orleans who wields an electric sword and wears a modified fencing outfit. Former leader of the Honor Guard. Recently retired.
- Black Velvet - A mysterious woman with shadow-like powers and a grim demeanor. Became the partner of the Street Angel. Apparently killed by the time-traveling Silver Agent after her powers went out of control.
- The Blue Knight - A gun-toting vigilante who wears a police-style riot mask with a ghostly skull outlined by a blue glow for a face. He takes very direct, very violent action against the criminals that he hunts, usually killing rather than capturing them. A frightening crime-fighter who stalks quietly and delivers justice from the barrel of a gun. Active from 1972 to the early 1980s, and a representative example of the type of violent, vengeance-driven hero that emerged during that period. Rumors abound about his current status, but no definitive sighting has occurred since 1988. Possible successors - the Blue Knights - were active during the early to mid-1980s.
- The Bouncing Beatnik - Fourth in a succession of counter-cultural heroes, all incarnations of the same being. Previously incarnated as Zootsuit and afterwards as the Halcyon Hippie. He was active in the 1950s and early 1960s. An early and frequent ally of the Honor Guard, although he never formally joined the team; Leopardman and much of the public considered him unduly frivolous.
- Bravo - An originally Los Angeles-based hero who started out as el Hombre's sidekick in the early 1970s and struck out on his own after his patron's disgrace, moving to Astro City and founding the Astro City Irregulars. Now retired as a superhero, he serves as Detective Ruiz on the Astro City's police force, and apparently long remained the secret patron of the group he founded.
- Broadsword - A sword-wielding vigilante active in the mid-1980s, and a representative example of the type of violent, vengeance-driven hero that emerged during that period.
- The Broken Man – Eighth in a succession of counter-cultural heroes, all incarnations of the same being. Reintegrated in the 1980s after being "shattered" during the interrupted transition between his sixth and seventh incarnations. Broken again in a subsequent confrontation with his nemesis, the Oubor, he physically returned in a different form as a minimally functional madman, while continuing to manifest psychically in his Broken Man form. Symptoms of his condition include apparent brain damage that leaves him unable to connect with music or communicate effectively with most people, who hear his speech as gibberish. Those to whom he manifests are usually unable to perceive or remember him after a few seconds, apparently due to the Oubor’s influence. The Broken Man has been observing Astro City and related characters for decades, and more recently has reached beyond the fourth wall to enlist the readers of the Astro city comic book in his efforts to bring down the Oubor.
- Cleopatra - A magical heroine whose primary weapon is a mystical staff. The name and staff have been borne by two women in succession, the second of whom is also super-strong. The first Cleopatra was a founding member of the Honor Guard in the late 1950s who fought Steeljack in the early 1970s; the current version is also a member. Exact details of their powers and origins have yet to be revealed, but they seem inspired by the heritage of Classical antiquity.
- The Cloak of Night – A shadowy Prohibition era hero who fought against bootleggers and racketeers. Described as often vanishing without a trace and is rumored to have been a vigilante who didn't have quarrels with killing. His eyepieces, surviving as an artifact, are said to be capable of identifying people in imminent peril of death; this quality was recently confirmed by Steeljack.
- Commander One - Fully spacesuited, jetpacked leader of The Apollo Eleven.
- Commando K - A hero or hero group of the 1940s and 1950s, believed lost near Pyongyang during the Korean War, during which the All-American was killed. Possible connection to the All-American's sidekick, Slugger the Junior Dynamo.
- The Confessor - The first Confessor was Jeremiah Parrish, originally a nineteenth-century Catholic priest who came to what became Astro City in 1869 to help Cardinal Grandenetti build Grandenetti Cathedral. Given administrative duties, including the importation of materials and dealing with immigrant workers from Eastern Europe, he was killed by a vampire, becoming a vampire himself. Fighting his hunger for blood he resorted to study, and after his discovery, to seclusion for decades. Inspired by the example of Air Ace and other early public superheroes, he eventually became one himself, apparently in the late 1940s or early 1950s. Despite his lengthy career, no photos of him existed, although few if any members of the public realized this was due to his vampiric nature. Active into the mid-1990s, when he sacrificed himself to expose the Enelsian invasion, revealing himself as a vampire in the process. A patron of Butler's in civilian guise. A few years after his death, his apprentice Altar Boy became the second Confessor, allowing the underworld to believe that he is Parrish, which prompts them to react with anti-vampire measures which are useless against the strictly mortal Kinney.
- Coyotl - Native American hero combining human and coyote attributes, pre-dating European settlement active in the area that would in time become Astro City. Used a bow and arrows. Possibly empowered by the magic amulet that later created Stormhawk and G-Dog.
- Crackerjack - An egocentric and reckless blowhard with amazing agility and a staff weapon. Active since 1991. he reflects the disconnect that frequently existed between superheroes' sterling public personas and unappealing private behavior. Possessing no super-powers, he is dedicated to his superhero career to the point of obsession, to the extent of refusing to allow increasing human limitations to curtail his activities. Recently retired by age and debilitating injuries; his lover Quarrel has taken charge of his physical rehabilitation, much as he took charge of hers earlier in their relationship.
- Dame Progress - A "steampunk" heroine who operated out of Romeyn Falls around the very end of the 19th century.

- The Flying Fox — A non-powered crimefighter who uses an aero-cycle for transportation; rumored to be a lesbian and is in fact openly gay in her civilian life. Somewhat ironically, her mother was also involved with the '60s superhero Atomicus, and was responsible for his abandoning Earth. Is the second hero to use the name.
- The Frontiersman - A hero of the 1950s who dressed like Davy Crockett in a domino mask, smoked, and appeared in Frontiers cigarette advertisements. Active as late as 1959. Apparently died of lung cancer.

- The Hanged Man - A ghostly figure who protects Shadow Hill. He appears to be a jet-black corpse with a burlap sack over his head and a noose around his neck. Invariably seen as a floating apparition, usually human-scaled, although it can also expand to great heights. His specific powers are unknown, but appear to include a kind of empathy that guides him to those in need of comfort after traumatic events. Active since at least the 19th century; rumored to have existed since the Middle Ages.
- Hawk of the Alleyways - Costumed vigilante active in the 1920s.
- Hellhound - A Vietnam War veteran transformed into a monster by black magic, active from the early 1970s into the mid-1980s.

Disgraced in April 1973 by the misfire of a crisis he manufactured to restore his fading reputation, he became a recluse haunted by his failure and eventually declined into insanity. In 1998, intending to reprise his earlier scheme in order to relaunch his heroic career in the new guise of el Guerrerro, he masqueraded as the villainous Conquistador and incidentally became the Black Mask Killer.

With help from the Honor Guard, Hummingbird raised her daughter to learn her talents and become the new Hummingbird.

- Manny Monkton - The editor of an Astro City-based comics company, Bulldog Comics, he is responsible for the comics based on real-life superheroes. Manny is a long-time veteran of the comic-book industry shown at one convention answering questions with Stan Lee. A smooth-talking, shrewd and deceitful little man, he ostensibly publishes comics based on actual adventures the heroes have, but always changes the stories around to make them more marketable. He has a deal with Crackerjack, allowing him to legally exploit his fame through excessive merchandise, but always withholds Crackerjack's share on the grounds that it is not selling. He has come under considerable attack from numerous heroes and villains, but stubbornly refuses to change his stories. He gets his comeuppance when he publishes a comic featured Jack-in-the-Box and Glowworm, based on a real fight they had but changing details to make Glowworm seem more villainous; among the things he adds is the implication that Glowworm is a racist. Sometime later, the real Glowworm bursts in on him, and, furious to be called a racist, beats Monkton severely. Soon after, Monkton decides to instead start writing about cosmically powered villains and heroes instead, deciding that they would not be concerned enough to harass him. However, he misjudges, and, one day, he is yanked out of existence along with the building he is in, and never seen again.
