Power Girl
Since she is from an alternative universe (pre-Crisis Earth Two), kryptonite has no effect on her, but she is still vulnerable to magic. As Karen Starr, she is an accomplished business woman and is regarded by Mr. Terrific as a first rate scientist. Even though Power Girl is from an alternative universe, her biology is still similar to Superman's. As one of a handful of characters who survived the "Crisis on Infinite Earths", DC editorial was initially uncertain how to portray the character and attempted to portray Power Girl with a non-Kryptonian origin for a number of years. Power Girl's abilities have fluctuated since 1986. For some time, Power Girl believed she was an Atlantean. At one point, Power Girl possessed telekinesis; at another she was vulnerable to attacks by certain natural elements (for example, wooden weapons). After sustaining severe injuries from a magic attack Power Girl retained only a degree of super strength, speed and durability. However, she later recovered her ability to fly, and writers have gradually restored her superpowers.
