by DC Supergirl tries to figure out who she is and who her friends are, so she seeks out the other cousin of Superman, Power Girl, but when they touch, Power Girl goes haywire, attacking everyone.
Supergirl fights Power Girl, trying to stop her without hurting her, but it only seems to make things worse. Finally, Mr. Terrific gets an idea. He tells the Green Lantern, Alan Scott, to use his ring to contain both Supergirl and Power Girl. Once everyone has calmed down, it becomes apparent that Power Girl didn't even know what she was doing.
Apparently, Power Girl's powers have been going crazy ever since Supergirl arrived on Earth and it's dangerous for the two to touch. Power Girl decides to leave a saddened Supergirl, but Stargirl manages to get her to meet Supergirl again, this time atop the Statue of Liberty.
Power Girl's response to Supergirl's offer of friendship is less than friendly, but Power Girl claims that's more to do with herself than with Supergirl. Power Girl was just starting to get used to the idea of being Superman's cousin when Supergirl comes along and now Power Girl can't even have that to herself -- Supergirl, meanwhile, knows exactly what she means.
