Yes, it has been confirmed that Kara Zor-El or popularly known as Supergirl is in the Man of Steel universe as confirmed by the Man of Steel prequel tie-in comic book. But the big question is, will Supergirl appear in the Man of Steel 2 or as it's popularly called "Batman vs Superman"? Read on and you'll see why a "Batman vs Superman" Supergirl reference or appearance is possible!

For everyone who has read the Man of Steel prequel tie-in comic knows that the ship Clark Kent found in ice belongs to Supergirl aka Kara Zor-El. Kara Zor-El is the daughter of Zor-El, the brother of Jor-El.

At the end of the prequel comic, Kara Zor-El ended up on Earth more than a thousand years before the events of Man of Steel happened. Now when Clark Kent went to ship you can see that one of the pods have been opened. This is presumably, Kara Zor-El's pod.

Where could she have gone? This is where the "Batman vs Superman" Supergirl theory comes in.

After waking up from the pod, Kara Zor-El explores the Earth and finds it without highly evolved creatures (humans haven't evolved yet) so she finds an isolated area she's comfortable and uses the birthing matrix or whatever the Kryptonians use to make children to populate the isolated area. This area would then become "Themyscira" the birthplace of Wonder Woman and the rest of the Amazonians. Of course since Kara Zor-El would be the first one there, she will be dubbed the ancestor of the Amazonians.

Now this will be very interesting as Kryptonians age slower than a human. Jor-El was alive when Kara Zor-El was sent away from Krypton and Jor-El died just decades before Man of Steel happened and Kara Zor-El's ship crashed thousands of year prior so it can be assumed that she is still alive after thousands of years.

What do you think? Will Kara Zor-El appear or be referenced in the Man of Steel 2/ Batman Vs Superman? Sound off in the comments below!
