Power Girl made her debut in February 1976 in All Star Comics #58, created by Gerry Conway, Ric Estrada, and Wally Wood for DC Comics. The Kryptonian cousin of Earth-2's Superman and civilian alter ego of Karen Starr, she established herself as a cornerstone of the Justice Society before earning her own solo series in 2009 under Justin Gray, Jimmy Palmiotti, and Amanda Conner. This guide covers her origins, her full biography, a complete series timeline, the key issues every collector should know, and the major story arcs worth tracking down.
Power Girl holds a singular place in the DC Comics lineup. Introduced in 1976 as part of the Justice Society revival, she spent years as an alternate take on Supergirl before carving out an identity of her own — one shaped by four decades of retcons. Her first appearance in All Star Comics #58 marked the arrival of an adult Kryptonian heroine in the DC catalog at a moment when the publisher was actively broadening its roster of female characters. The initial print run was modest compared to contemporary Superman and Batman titles, which is exactly why high-grade copies are so prized by collectors today.
This article covers the character's editorial origins, Kara Zor-L's full biography, a complete chronology of her solo series and major appearances, the top 10 key issues to know, and the defining runs that shaped Power Girl. For a closer look at graded issues and market values, the article on Supergirl key issues offers a complementary perspective on DC's Kryptonian heroines.
Power Girl Biography
Power Girl is a DC Comics character created by Gerry Conway, Ric Estrada, and Wally Wood. She first appeared in All Star Comics #58 (February 1976). Originally conceived as the Earth-2 counterpart of Supergirl, she survived multiple continuity overhauls — Crisis on Infinite Earths, Infinite Crisis, the New 52 — while retaining her distinctive visual identity and her role as a pillar of the Justice Society of America.

Character Origins
Gerry Conway and Ric Estrada introduced Power Girl as part of the Justice Society of America revival — DC's legendary Golden Age team brought back to capitalize on nostalgia among longtime readers. The publisher needed a young figure who could bridge the aging JSA and newer generations of fans. Choosing a Kryptonian cousin from Earth-2 let them repurpose the Superman mythology while opening up fresh narrative territory. In-universe, Kara Zor-L was sent from Krypton by her father Zor-L aboard a ship whose journey stretched across several decades, which explains why she arrived on Earth-2 as a fully grown adult. She quickly adopted the civilian identity of Karen Starr, a tech-company CEO, and joined the Justice Society. Crisis on Infinite Earths in 1985 erased Earth-2 from the multiverse, forcing writers to rewrite her backstory — setting off a string of retcons (Atlantean heritage, an Earth-22 version, a return to Kryptonian roots) that wasn't fully resolved until the 2005 reboot definitively restored her status as the Supergirl of Earth-2.
Powers and Abilities
- Flight: supersonic aerial travel, standard for any Kryptonian under a yellow sun.
- Superhuman strength: on par with Superman, capable of lifting enormous loads.
- X-ray vision: able to see through most materials, with the standard lead exception.
- Super-breath: can emit freeze breath or powerful gusts of wind, enough to extinguish fires from a distance.
- Enhanced Kryptonian senses: super-hearing, telescopic and microscopic vision, and heat vision depending on the era.
Costume and Visual Identity
Power Girl's signature costume combines white, blue, and red — a long-sleeved white top, red cape, and blue boots. The most iconic element is the circular cutout at the chest, which Amanda Conner famously addressed with self-aware humor throughout her 2009 run. Several creative teams tried to close or redesign it (most notably in the New 52 continuity in 2011), but the classic look always reasserted itself. The red cape fastened with two gold clips, paired with long white gloves, rounds out a silhouette that has remained essentially unchanged since Wally Wood first drew it.
Power Girl Series Timeline
Power Girl's publishing history alternates between team books (JSA, Justice League Europe, Birds of Prey) and sporadic solo series. Here are the key titles to know when building a structured collection.
All Star Comics (revival)
The Justice Society revival helmed by Gerry Conway is where Power Girl made her debut. The earliest issues, penciled by Ric Estrada and inked by Wally Wood, established the character's visual foundation and her dynamic with the JSA veterans. This series is the cornerstone of any Power Girl collection.
Showcase #97-99 (Power Girl mini)
The character's first extended solo showcase, this three-issue arc explores Kara Zor-L's Kryptonian past and her adaptation to life on Earth-2. Written by Paul Levitz with art by Joe Staton, it laid the mythological groundwork that later writers would build on.
Power Girl (1988 mini-series)
The first attempt at relaunching the character after Crisis on Infinite Earths. Paul Kupperberg rewrote her origins to fit the unified continuity, temporarily giving her an Atlantean heritage. The run has since been largely undone by later retcons but remains useful for understanding the chronology.
Power Girl (2009 series)
Justin Gray and Jimmy Palmiotti on scripts, Amanda Conner on art — this is the definitive solo series for the character. Light in tone, leaning into superhero comedy and playful self-parody, the first twelve issues are the universally recommended entry point for new and veteran collectors alike.
Worlds' Finest (New 52)
Under the New 52, Power Girl and Huntress find themselves stranded on the main DC Earth, far from their home world. Paul Levitz scripts their quest to return, drawing on the Earth-2 legacy throughout. A key series for understanding the modern version of the character.
Power Girl Top 10 Key Issues
This selection prioritizes first appearances, editorial milestones, and covers that have consistently performed on the secondary market. For a deeper issue-by-issue look at the Kryptonian side of the DC roster, the article on Supergirl key issues is a natural companion read.
All Star Comics #58
The absolute cornerstone: Power Girl's first appearance, by Gerry Conway, Ric Estrada, and Wally Wood. This is the number-one target for any serious Power Girl collector. High-grade copies are scarce — the newsprint paper of the era is highly susceptible to oxidation and brittleness.
All Star Comics #64
The first cover to feature Power Girl as the sole lead. Sought after as an editorial milestone and for the visual stamp of Wally Wood's work. Prices on CGC 9.0 and above copies have climbed steadily.
Showcase #97
The opening chapter of Paul Levitz and Joe Staton's three-part solo arc. Details Kara Zor-L's Kryptonian origins. Historically more affordable than #58, making it a solid entry point for collectors building out a Power Girl run.
Justice League of America #147
Power Girl takes part in the annual JLA/JSA crossover alongside the Legion of Super-Heroes. An important issue for collectors who cross Legion and JSA material, and a key moment in cementing the character's place in DC's broader continuity.
Crisis on Infinite Earths #7
The pivotal Crisis issue featuring the death of Earth-1's Supergirl — an event that forced writers to reimagine Power Girl as the last surviving Kryptonian woman. Essential for understanding the retcon machinery that defined the character for decades.
Power Girl #1 (1988)
The debut issue of the solo mini-series by Paul Kupperberg and Rick Hoberg. Introduces the (later retracted) Atlantean origin and begins the visual and narrative separation between Power Girl and the Superman mythology. Worth holding as a historical milestone.
JSA Classified #1
Geoff Johns, Amanda Conner, and Paul Kupperberg launch the "Power Trip" arc, definitively restoring Kara Zor-L's status as the Supergirl of Earth-2. This is Conner's first major work on the character — the collaboration that would lead directly to the 2009 series. Highly sought after.
Infinite Crisis #1
Power Girl plays a pivotal role in Geoff Johns' Infinite Crisis saga. The event confirms her Earth-2 heritage and cements her status as a founding member of the new JSA. A must-have for any thematic Power Girl collection.
Power Girl #1 (2009)
The launch issue of the definitive solo series by Amanda Conner, Jimmy Palmiotti, and Justin Gray. A perfect blend of action and comedy, with Conner's instantly recognizable art refreshing the character's look. High demand for both the iconic Conner cover and its role as the modern entry point for new readers.
Worlds' Finest #1 (2012)
The debut issue of the shared series with Huntress under the New 52 banner. Written by Paul Levitz with art by George Pérez and Kevin Maguire. A pivotal issue for the contemporary version of the character and for readers following both Huntress and Power Girl.
Major Story Arcs and Cult Runs
Power Trip (JSA Classified #1-4, 2005) — Geoff Johns and Amanda Conner definitively settle the question of Power Girl's origins, confirming Kara's Earth-2 identity. Essential reading for anyone who wants to understand the modern character. Power Girl (2009-2011, vol. 1-3) — the Palmiotti/Gray/Conner run is the gold standard for the character. Light tone, sharp treatment of Karen Starr's life as Starrware CEO, memorable antagonists (Ultra-Humanite, Vartox). The first two collected volumes are required reading. Worlds' Finest (2012-2014) — Paul Levitz extends the character's dynamic into a duo with Huntress, playing on Earth-2 nostalgia within the constraints of the New 52. Earth-2 (2012-2015) — James Robinson, then Tom Taylor, send Power Girl back to her home world in a darker reimagining where she temporarily fills the Superman role. A structurally important arc for understanding the character post-2011. JSA (1999-2006) — Geoff Johns and David Goyer's landmark run establishes Power Girl as a true team anchor, including her complicated relationship with her own legacy. Best read in omnibus format for a cohesive experience.
Adaptations and Cultural Impact
Power Girl has remained relatively low-profile on screen compared to DC's frontline characters. She appears in several episodes of the animated series Justice League Unlimited (2004-2006) and in the digital-format Smallville Season 11. The character also features in Injustice: Gods Among Us (2013) as an alternate skin and in DC Universe Online. The CW series Stargirl (2020-2022) references JSA mythology without actually introducing the character. On the market side, every new rumor of an adaptation has traditionally triggered a run on All Star Comics #58 — a pattern clearly observable in 2019 and again in 2022 following successive DC Studios announcements. Key issue prices have broadly tracked the upward trend across DC Golden and Bronze Age titles since 2020.
