Mermaid

Mermaid is a superhero inhabiting the richly layered world of Astro City, the independent city filled with costumed heroes. An aquatic-themed character, she has operated alongside prominent Astro City figures including Cleopatra, Quarrel, and the Silver Agent.

Emerging from the richly imagined world of Astro City in 1998, Mermaid is one of Kurt Busiek and Brent Anderson's contributions to that beloved universe of deeply human superhero storytelling — a character who has kept remarkable company over nearly three decades, sharing adventures with icons of that world like Cleopatra, Quarrel, the Silver Agent, and Hummingbird. With 17 catalog appearances spread across Astro City's various collected editions from 1998 all the way to 2025, she's a figure woven into the long, ongoing tapestry of one of comics' most thoughtfully crafted settings. For fans who love superhero fiction with genuine heart and a world that rewards close attention, Mermaid is exactly the kind of character Astro City does so well — part of a cast that feels lived-in and real.
