Supergirl was a cousin of Superman and an ally of the Justice League.

Kara Zor-El was born in Argo City, a Kryptonian city which survived Krypton's destruction. When disaster struck the floating city, her parents Zor-El and Alura In-Ze sent her to Earth, the planet where lived her cousin Superman. Kara created her Linda Lee civilian identity, was adopted by the Danvers family, and took up the Supergirl moniker. Supergirl started operating in the town of Midvale, adopted a cat whom she called Streaky and eventually she joined the Justice League.

When six mysterious robed figures called the "Rainbow Ghosts" started roaming about the Hall of Justice and caused Superman to vanish, Kara was tasked with filling in for her cousin as Mistery, Inc. investigated the case. However, the Rainbow Ghosts struck before they were ready, forcing Kara to get the young detectives to safety while the League dealed with the threat. Unfortunately two ghosts reached them and one of them encased Kara in a coffin of solid yellow light. Then the "Ghosts" revealed themselves to be the Legion of Doom.

During the subsequent chase, Mistery Inc. managed to find the missing Leaguers, shrank by Brainiac's tech. Shaggy Rogers and Scooby-Do got Sinestro to slip his concentration by accident, which allowed Supergirl to break free just in time to stop Lex Luthor from blasting her teammates and Mistery, Inc. to pieces.

Some while later, Kara and her adoptive parents found themselves haunted by the the ghosts of the people of Argo City, including her parents, demanding to know why Supergirl didn't save them. Worried and upset, Kara thought of calling Mistery, Inc. to help her out.

It turned out the ghosts were a ploy of her enemy Nasty to discover her secret identity. Kara threw Nasty off, but her scheme reminded her how she missed her birth parents.


  • Kryptonian Physiology: Under the effects of a "yellow" sun, Supergirl possesses the same potential powers as an average Kryptonian. These include:
    • Solar Energy Absorption: Under optimal conditions, this is the main source of Supergirl's super powers as they are contingent upon exposure to solar radiation from a yellow sun star system. Her biological make up includes a number of organs which lack analogues in humans and whose functions are unknown. It is believed that between one or more of these and her bio-cellular matrix, "yellow" solar energy is stored for later use. This allows for the use of these powers to fade when yellow solar radiation is not available instead of immediate failure.
    • Heat Vision: Supergirl can, as a conscious act, fire beams of intense heat at a target by looking at it. She can vary the heat and area affected.
    • Super-Hearing: Supergirl's hearing is sensitive enough to hear any sound at any volume or pitch. With skill and concentration, she can block out ambient sounds to focus on a specific source or frequency.
    • Enhanced Vision: Supergirl's vision processes the entire electromagnetic spectrum as well as allowing vast control over selective perception and focus.
      This umbrella ability includes the following:
      • Electromagnetic Spectrum Vision: Supergirl can see well into most of the electromagnetic spectrum. She can see and identify radio and television signals as well as all other broadcast or transmitted frequencies. Using this ability, she can avoid detection by radar or satellite monitoring methods. This also allows her to see the aura generated by living thing.
      • Telescopic Vision: This is the ability to see something at a great distance, without violating the laws of physics. Though limited, the exact extent of the ability is undetermined. In function, it is similar to the zoom lens on a camera.
      • X-Ray Vision: This is the ability to see through any volume of matter except lead. Supergirls can see things behind a solid, opaque object as if it were not there. She can focus this ability to "peel back" layers of an object, allowing hidden image or inner workings to be observed. The exact type of energy perceived—such as x-rays, cosmic rays, or some other energy invisible to normal humans—is unclear. This ability perceives an ambient energy source though, it does not involve the eye projecting a concentrated, possibly toxic, beam to be reflected back from objects.
      • Microscopic Vision: This is the ability to see extremely small objects and images down to the atomic level.
      • Infrared Vision: Supergirl can see with better acuity in darkness, and to a degree in total darkness.
    • Flight: Supergirl is able to manipulate graviton particles to defy the forces of gravity and achieve flight. This ranges from hovering to moving in any posture, in any direction.
    • Invulnerability: Due to the interaction of her dense molecular structure and supercharged bio-electric aura, Supergirl is nigh-invulnerable to extreme energy forces. In addition, her extends this protection against toxins and diseases.
    • Superhuman Stamina: Supergirl is able to maintain continuous strenuous physical action for an indefinite period of time. This based on her body converting yellow solar radiation directly to energy, but is limited by physiological and psychological needs to eat, drink, and sleep.
    • Superhuman Strength: Supergirl's strength is augmented by yellow solar radiation interacting with the greater than human density, resilience and biological efficiency of her musculature. Her strength is more an act of conscious will on energy fields than actual physical strength. It is this act of conscious will that enables her to perform physical feats that are beyond the mere application force, such as moving a mountain top without said rock crumbling under its own mass.
    • Superhuman Speed: Supergirl is able to move at incredible speed by sheer force of will. This extends to her perceptions and allows for feats such as catching bullets in mid flight as well as covering vast distances in little or no time.
      This also confers:
    • Super-Breath: Supergirl is able to create hurricane force winds by exhaling air from her lungs. She can chill the air as it leaves her lungs to freeze targets. She can also reverse the process to pull large volumes of air or vapor into her lungs.
    • Longevity: Supergirl can live longer than regular humans, remaining at her prime as long as she was under the exposure of the "yellow" sun.


This version of Supergirl first appeared in Scooby-Doo! Team-Up #6 by Sholly Fisch and Dario Brizuela and is an adaptation from the original Supergirl/Kara Zor-El created by Otto Binder and Al Plastino which first appeared in Action Comics #252.
