Kara Danvers (born Kara Zor-El) is the daughter of Zor-El and Alura Zor-El. Kara is also the cousin of Kal-El, the adoptive daughter of Jeremiah and Eliza Danvers, the adoptive sister of Alex Danvers, the ex-girlfriend/friend of James Olsen, the girlfriend of Mon-El, the best friend of Lena Luthor, and a good friend of Winn Schott, J'onn J'onzz, Lois Lane, Barry Allen, Iris West-Allen, Caitlin Snow, Cisco Ramon, Felicity Smoak, John Diggle, Sara Lance, and Oliver Queen, as well as a reporter for CatCo Worldwide Media.

Kara was sent to Earth from the dying planet of Krypton to protect her younger cousin, Kal-El. However, Kara's pod got knocked off-course by Krypton's explosion, sending her ship into the Phantom Zone where she slept for 24 years, while being suspended in time and not aging. Her pod later escaped, and Kara arrived on Earth, where she was placed with the Danvers family by a now-adult Kal-El, who was known to the humans as "Clark Kent". She decided to move to National City with Alex and have a normal life, being Cat Grant's assistant at CatCo. Kara was forced to reveal herself to save an crashing airplane that Alex was. She was nicknamed Supergirl by Cat Grant, and stylized as the "Girl of Steel".

Powers and abilities


  • Kryptonian physiology: Normally, like all Kryptonians, Kara's capabilities are no greater than a normal human of her physical conditioning. However, once charged by the energy spectrum of a yellow sun, she becomes able to perform various inhuman feats. While generic for her race, having grown up half of her biological life with these powers have allowed her to use these abilities with far greater control and an equally greater level of raw power compared to other Kryptonians.
    • Solar energy absorption: While Kara's powers are dependent on the energy spectrum from a yellow sun, her body is able to constantly and passively absorb such energy while exposed to it, essentially keeping her reserves fully charged near-constantly.
      • Accelerated healing factor: Kara's metabolism is tremendously enhanced by solar energy, allowing accelerated healing abilities and burning calories at a superhuman rate, making her practically immune to becoming fat or obese.
      • Flight: Kara is able to manipulate her own gravitational field to generate thrust and propel herself through the air, often at hyper-sonic speeds, much faster than she can travel by foot.
        • Levitation: Kara can levitate using her flight abilities.
      • Heat vision: Kara can emit blue energy beams of intense heat from her eyes.
      • Invulnerability: Kara is essentially invulnerable to all Earthly weapons, with bullets simply ricocheting whenever they come into contact with her skin.
        • Self-sustenance: Due to the effects of a yellow sun, Kara's physical needs are greatly reduced.
        • Atmospheric adaption: While Kara does require oxygen, her physicality and exposure to a yellow sun allows her to survive while inhaling more harsh forms of it such as the thin, highly CO2-concentrated, atmosphere of Mars.
      • Superhuman senses: Kara has super senses, including super vision and super hearing.
        • Superhuman vision: As a Kryptonian, Kara is able to see very far distances, presumably low superhuman levels.
        • Night vision: Kara can see clearly in the dark.
          • X-ray vision: Kara has the ability to see through objects, except for lead.
        • Superhuman hearing: Kara has super-sensitive ears that can perfectly pick up sounds from miles away and even through structures.
      • Freeze breath: Kara is able to exhale powerful gusts of air from her mouth which are similar to force winds. She can also cause the temperature of her breath to drop, therefore able to freeze nearly anything.
      • Superhuman speed: Kara possesses the ability to move at hyper-sonic speeds, both through flight and on foot. Once she started to actually use her powers in a less restrained way, she was easily able to move at even greater supersonic speeds to the point where she could match a tachyon-enhanced speedster like Barry Allen.
        • Accelerated perception: While using her super speed, Kara sees everything much slower; allowing her to move with precision and accuracy within very fast moments.
        • Superhuman reflexes: Kara's reflexes are so fast, she can respond to attacks within seconds.
      • Superhuman strength: Kara's strength is augmented by yellow solar radiation interacting with the greater than human density, resilience and biological efficiency of her musculature.
      • Superhuman jumping/Leaping: Kara is able to jump several feet off the ground and leap several stories in a single bound without having to fly.
      • Superhuman stamina: Kara can run, fight or fly for long periods of time, without getting tired.
    • Extended longevity: As a Kryptonian and the powers that gain from the yellow sun, Kara's life span is considerably longer than a normal human and likewise ages much slower.


  • Expert investigator/Journalism: Since becoming a reporter, Kara proved to be an effective investigator with strong instincts.
  • Bilingual: Kara is capable of fluently speaking English and Kryptonese.


  • Kryptonite: Like all Kryptonians, even while empowered, Kara is vulnerable to the exposure of Kryptonite, a radioactive mineral from her home planet Krypton. Depending on the nature of the said Kryptonite, it will cause a different adverse affect on her;
    • Green Kryptonite: Green Kryptonite not only physically hurts Kara, but also it weakens her physical attributes; making her equivalent to that of a normal human. If exposed to enough green kryptonite for too long, it will eventually kill her.
    • Red Kryptonite: If exposed to Red Kryptonite, it gradually destroys Kara's inhibitions and turns her into a corrupt version of herself. Left without morality, compassion, rationality, or any cares whatsoever, Kara will become malevolent and prone to hostility and aggression, making her a danger to everyone around her.
    • Silver Kryptonite: If exposed to Silver Kryptonite, it will cause Kara to go in a deep and frightful hallucination where nothing from the outside world can stir her out of it until it leaves her system.
    • Harun-El/Black Kryptonite: If directly exposed to Black Kryptonite, it can hurt Kara and cause her to lose control of her abilities, as she was unable to stop her heat vision while holding Harun-El.
  • Red sun energy: Kara is powerless when exposed to the energy of a red sun.
  • Blue sun energy: Kara is powerless when exposed to the energy of a blue sun.
  • Solar energy depletion: Using her powers to its maximum for an extended period can significantly drain her solar energy to the point where Kara loses all of her powers and is rendered more human-like for at least a day. This renders her as weak as a human - allowing Kara to get injured, sick, and killed like one.
  • High-frequencies: Although considered a strength, Kara's hearing does have its disadvantages; since her hearing is more sensitive than a normal human's, higher pitch noises (sonic screams, etc.) can disorient Kara and cause pain in her ears, leaving her vulnerable in a fight.
  • Sound-dampening technology: The D.E.O. designed frequencies to block super-hearing and cause Kara slight pain when trying to use this ability in areas protected by the technology.
  • Power-dampening tech: Just like with any other alien, Kara's powers can be dampened by technology specifically designed to weaken her powers but even though it's dampening her powers she can still use her powers but at a much weaker degree.


  • Supergirl suit: Kara wears a protective suit as her super-heroine alter-ego, Supergirl, to hide her identity from her enemies when out fighting crime.



Behind the scenes

  • Kara Zor-El debuted in Action Comics #252 (May 1959) as the cousin of Superman, who was rocketed from Argo City before its destruction. She later died in the Crisis on Infinite Earths (October 1985) event. Kara was later re-introduced into the DC continuity in Superman/Batman #8 (2004). She was created by Otto Binder and Al Plastino.
