Edward Nygma, aka The Riddler, has the world's first doorway to any part of the world. Or so he thought. Instead, he accidentally created a bridge between his world and the multiverse. Happening upon the other side of the activated bridge, a young adult from a different world falls through to Gotham in the middle of Batman stopping Edward's first run of the "Matter Transmitter". Just as she falls through, the machine is destroyed. How will she get back home? How will Edward react upon finding out his machine wasn't what he thought it was? What will Batman do with the Universe Jumper? (I would love to say I own everything in here. But I don't. The only things I own is the invention and my little OC. So everything belongs to their rightful owners, blah blah blah.)
