Power Girl

Power Girl is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Power Girl rather than just read about it. In short: Power Girl, also known as Kara Zor-L, Karen Starr, and Paige Stetler, is a superheroine appearing in American comic books by DC Comics, making her first appearance in All Star Comics #58 (January/February 1976). Power Girl is the cousin of the superhero Superman, but from an alternate universe in the fictional multiverse in which DC Comics stories are set.

Key takeaways

  • Power Girl belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Power Girl to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Power Girl from memory before moving on to harder problems.

Reference excerpt

Power Girl, also known as Kara Zor-L, Karen Starr, and Paige Stetler, is a superheroine appearing in American comic books by DC Comics, making her first appearance in All Star Comics #58 (January/February 1976). Power Girl is the cousin of the superhero Superman, but from an alternate universe in the fictional multiverse in which DC Comics stories are set. Originally hailing from the world of Earth-Two, first envisioned as the home of DC's wartime heroes as published in 1940s comic books, Power Girl becomes stranded in the main universe where DC stories are set, and becomes acquainted with that world's Superman and her own counterpart, Supergirl. In common with Supergirl's origin story, she is the daughter of Superman's aunt and uncle and a native of the planet Krypton. The infant Power Girl's parents enabled her to escape the destruction of her home planet by placing her in a rocket ship. Although she left the planet at the same time that Superman did, her ship took much longer to reach Earth-Two. On Earth, as with other Kryptonians, Power Girl discovered she possessed abilities like super strength, flight, and heat vision, using which she became a protector of innocents and a hero for humanity. Though the specifics of how vary over subsequent retellings, Power Girl is later stranded on another Earth when a cosmic crisis affects her home of Earth-Two, and later carves out a separate identity for herself from her dimensional counterpart Supergirl once they are forced to coexist. Although she and Supergirl are biologically the same person, there are vast differences between the two. Power Girl is older and more level-headed due to her maturity, and her fighting style is more aggressive. She also adopts a different secret identity from her counterpart. These changes are reflected in their differing costumes and superhero names as well; Power Girl sports a bob of blond hair and wears a distinctive white, red, and blue costume with a cleavage-displaying cutout. The name Power Girl reflects that she chooses not to be seen as a derivative of Superman, but rather her own hero and this choice is reflected in the strong independent attitude of the character. Over various decades, Power Girl has been depicted as a member of superhero teams such as the Justice Society of America, Infinity, Inc., Justice League Europe, the Sovereign Seven, and the Birds of Prey. Power Girl's origin has gone through revisions, but over time has reverted to her original conception as the Supergirl of Earth-Two. The 1985 limited series Crisis on Infinite Earths eliminated Earth-Two from history, causing her to be retconned as the granddaughter of an Atlantean sorcerer known as Arion. This was an unpopular change and writers depicted the revised Power Girl inconsistently. The 2005–2006 Infinite Crisis limited series then restored her status as a refugee from the Krypton of the destroyed Pre-Crisis Earth-Two universe. This has been her consistent depiction ever since.

Worked examples

Example 1 — a first encounter with Power Girl

Start with the simplest possible case. Write down what Power Girl claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Power Girl before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Power Girl ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Power Girl

In research
Power Girl appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Power Girl in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Power Girl is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alternative versions of comics characters, Characters created by Gerry Conway, Characters created by Ric Estrada, so understanding it makes those chapters shorter.
In everyday life
Look for Power Girl outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
