Chosen by lightning.

Olivia Connors is just like any other teenage girl (tomboy kind). She has an attitude, hates being told what to do, etc. one day she is walking home from school in perfectly clear weather. Then, out of nowhere, she gets struck by lightning. But her parents don't think she was struck. They think she was chosen by the lightning. She recovers, but out of nowhere, she turns into electricity, and teleports across the room. She wonders, "What the hell just happened?!" She moves on, thinking it was all a dream. But then she gets so mad, lightning shoots out of her hands. She eventually grows used to her abilities, and with time, grows to be the hero,"Shock Wave" and be on the hero team, "Young Justice"
