Presenting Supergirl from the DC Elseworld's Finest one-shot.To the uninitiated, Supergirl is Kara Zor-El. This is of course an alternate universe separate from the main-stream DC universe (Elseworld, duh) where she is the last survivor not of Krypton, but of the destroyed Argo City. Sent to Earth.
In this reality, Kryptonians were actually aware of Earth's heroes and Supergirl grew up dreaming of joining their ranks. It is not disclosed what destroyed Krypton and, later, Argo City, but she is sent to Earth as a teenager and is welcomed into the ranks of the Justice Society of America and rises to become it's greatest and most popular hero just like her mainstream counterpart.
In this Elseworld however, Batman doesn't exist. Instead Barbara Gordon defends Gotham as Batgirl and has successfully seceded Gotham City from the rest of the United States to the point that no-metahuman can enter Gotham, where they are banned, without suffering dire consequences. Even the mighty Justice Society of America led by Wonder Woman cannot enter Gotham unless it's under Batgirl's terms.
