The Dimension Theory

"Just for the record, it was not my fault that we got transported to a different universe, met the Justice League and their incredibly obnoxious sidekicks, and then got powers."
"Really? That's your thoughts on the situation right now?"

As mentioned above, Ingrid Deck didn't ask for her science project to go horribly wrong. That meant that she didn't ask to be put in DC. It also wasn't her fault that her best friend, Terrance Ford, got dragged into the whole mess. It also means that it's very unfair that they both end up kicking butt as mysterious duo called Light and Darkness.
Clue to the powers are in the name.
Hint: Ingrid's always liked the colour black.
Are they going to let themselves be kicked around by the Justice League to "control their unstable powers"?
Absolutely not.

I OWN NOTHING EXCEPT THE PLOT AND INGRID AND TERRANCE
