A dark and moody 1990s hero, partnered with Sunbird.
In addition to being a skilled acrobat and martial artist, she can project a mist-like field of darkness. As Sunbird is the super-powered half of the team, this would seem to be a function built into Nightingale's costume rather than a bonafide power.
- It's wildly speculated that Nightingale and Sunbird are lesbians, but they neither confirm nor deny the allegations. It has also been speculated that they might be sisters, or perhaps a mother and daughter team of crime-fighters.
- Based on a partially blocked headline reading "Darklings Crushed by Sunhawk and Nightingale," it could mean that Sunbird has changed her name. It could also mean that Nightingale took on a new partner.
- Besides being partner to Sunbird, Nightingale and most of the street level heroes of Astro City seem to associate with each other on many occasions. In many of their appearances they seem to mention or joke about one another -- Crackerjack, Jack-in-the-Box, Quarrel, Sunbird, and Nightingale. Depending on the time-range, you might also throw Street Angel into the mix, along with the Irregulars.
