The untold saga of the superheroines

Once upon a time, Wonder Woman left Amazonia and came to a strange world. Among her many adventures, she endeavoured to inspire the young women of this strange place to follow a higher calling than the one their world placed upon them. One of these young ladies, who had always thought there was something better than this strange place, was enchanted by Wonder Woman's tales of adventure as she followed this different path. The young lady had many struggles of her own during the next few years, but due in a large part to Wonder Woman's example and encouragement, she managed to learn the code of the superheroes, though she was not yet one herself. Wonder Woman was kind enough to take the young lady as her protege, and though they carried on their own lives, they kept in constant contact. The young lady stayed in the strange place as Wonder Woman moved on, and continued to encourage the other young women. Though it was a challenge, she knew she could always call on Wonder Woman for advice and friendship. Then one day, everything changed.
Wonder Woman met Batman.

We all know what happens next...Wonder Woman again follows the higher calling and becomes the sidekick..Batgirl.

Who, of course, is still as amazing as ever. In fact, she had even greater adventures now that she had someone to share her victories with. And Batman was not as solemn as he once was. And we like him better that way.

But Wonder Woman/Batgirl knew it was time for her protege to take up the Lasso of Truth. Yet the young friend knew she could never do it. How could she possibly become Wonder Woman? She thought of all the times she'd failed when she was sure Wonder Woman would have saved the day...of all the times she had lived in Wonder Woman's shadow...and had not met the expectations.
She felt more like this:

Instead of the great superheroine she so admired.

It was a hard burden for the young protege. She went to the great Code Writer, whom she had known since childhood, and who Wonder Woman had encouraged her to grow closer to, and asked Him how she was ever to become Wonder Woman. She did not expect the answer He wrote in her heart.
She could never be Wonder Woman. She was not meant to be. Ah, she understood that her mentor did not mean her to be either...but to be who the Code Writer had destined her to become.
So the young protege gladly took up the Lasso of Truth...it's nice to know the bad guys aren't lying and can't escape...but also took up a new identity.
She became Supergirl. And it's not as though Batgirl and Supergirl can't have their adventures together.
In fact, they're going to save Boston with the help of a super Aussie chick this fall.
Supergirl and Batgirl will always be close.

And Supergirl is so definitely ready to save the world.
