Won't Back Down [Marvel/DC, Need XMEN/Sabertooth!]

It all started when a crystal dropped into existence, punched a hole in time and space and landed into the lap of one the most insane men to ever walk the Earth. At first, the clown didn't know what he had been gifted with, stuck in his cell in Arkham, staring at the reddish purple crystal laying innocently on the dirty stone floor. And then the voices started, telling him of another universe, talking of power and chaos beyond what he could have ever dreamed.

Joker knew he wasn't going to figure out what the voices wanted him to do with the crystal on his own, but it was a simple task to break out of the Asylum and go from there. After some interesting persuasion to a few other infamous names, the likes of Lex Luther, Victor Fries, and Hugo Strange to name a few and following the instructions of the voice that wouldn't stop buzzing in all of their head now, they rigged a contraption that harnessed the energy of the crystal and eager for the promised chaos, Joker flipped the switch, unaware of just what would happen next.

Their universe collided with that of the voices in their head. In a sudden, disorienting flash the maps of the world had changed, people and things that had never even been seen in a dream suddenly blinked into existence. The heroes of the world scrambled, unable to wrap their minds around what was going on and faced with the new super-powered beings of another universe distrust roamed through each side. Villains, criminals and rouges alike have taken seemingly banned together to make the best of the new found chaos, but there is no honor amongst criminals and it's quickly becoming clear that everyone has an agenda of their own. The heroes of the newly melded world need to come together before all is lost, they are the last line of defense and they need to show the world

that they won't back down
