Transformation (Character Development)

A little girl was skipping down the streets of JumpCity. She had a lollipop in hand and was licking it happily, looking like any other young girl of jump, except one thing. She had long white hair and pink eyes. There was a lot of meta's in Jump city, but not many of them were her age. She was already out of place, not being able to control her powers, but now her original home was blown up and she was the main act at a mundane circus. People clapped and cheered for the shape shifting girl, but now, Jolie had no friends. Her close friends/family have been blown up, she was lucky she threw a crying fit and ran off to get it over with, or she would have been blown to pieces to.

Now, trying to forget that, she was skipping through the streets. It was mid night, and regular girls her age wouldn't be out this late, but Jolie wasn't normal. She was pushed over by a man in a white coat, followed by two identical men carrying a mirror. They were running from a man with a baseball bat.
Jolie transformed quickly and in a few swipes, the man was knocked out. Jolie followed the men which dropped the mirror into a dumpster. She pulled it out, out of curiosity, and looked into it. She saw a tall woman with short spiky hair and piercings everywhere. Jolie pressed her hand onto the glass, which rippled like water. A hand reached out and pulled her through, throwing her on the ground.
She looked back in the mirror to see the girl on the other side, running away. Jolie pounded on the glass, looking around.

Little did Jolie know. That was the future her from an alternate dimension, and now the two Jolie's switched dimensions.
