Caroline ran through the streets of the broken city, everything was gone. Everyone, dead. Caroline was alone. She cursed at the sky as her running seemed to trigger a montage scene, causing "Sweet Caroline" to play from the heavens like a large, ethereal boombox.

This kind of thing happened all too often, not the apocalypse, but the music thing. The universe seemed to think it was her theme song or something. Caroline always found it odd when people would say,
"If my life had a soundtrack, it would sound like this,"
And Caroline was always tempted to say, "want mine?"

See, Caroline is everything but average, and that's not by mistake. The universe must have simply decided that, when she was conceived, she would be the main character of this story. Everything had always revolved around her, and she.was the most unique looking person ever. How do you think doctors explained to her parents when she was born with bright blue hair and heterochromic eyes, one was green, the other black. 

"Oh, she must be a main character," is what they had told her parents before they were both shot in an alley. This of course, could have prompted seven-year-old Caroline to become a superhero, but she didn't have any super powers, she also wasn't super rich. So young Caroline was an orphan now, it had been her fate since she was born. Everything she did seemed almost planned out in some way, and she could never describe it.
That's when she was sat down by the orphanage councilor and told that she was a main character. It was almost like telling her she was the chosen one, destined to destroy Voldemort and bring balance to the force when she through the ring into the fires of Mordor.
And now here she was, running through a wasteland, an apocalypse she could've stopped, if only she followed her destiny.
