The Dark force stared out upon the dimension of heroes. Taking in what had been accomplished... assured that soon it's power would stretch across the land and his control would be all consuming.
However, it's downfall ahd come by the power it had forgotten about. A Beauty Queen it had sent into the world to make some contestants for a fancy slave auction was flowing through the universe finding new heroes to taint. The heroes of the world that had yet to be affected managed to band together and stopped BQ's recruitment drive.
They quickly realized that she was merely a pawn in the grander scheme with a little ingenuity some of the magically inclined managed to use the link BQ had with the true culprit to send positive energy through it.
the energy charged it's way through the weaved web of darkness, reverting all of the changes made... rather quickly all the heroes and villains found themselves back in their original situations... without a memory of what exactly happened. The only lingering side effect was the occasional dream on the altered history.
The heroes had assumed the amount of positive energy would be enough to silence the entity forever... and they were almost right. The entity was hurt for certain... and lost a connection to the world but the heroes never truly understood the scope of its actual power... so it waited, plotted and reconsolidated it's power... until such a time when it could strike again...
Finally, on what was a snowy December in New York City... it finally had enough power to strike again... but how... the December Holiday Season had so many icons that it could corrupt.
A snowman that makes ice queens, some kinda Scrooge that rewards the Miserly, the were starts but no... they didn't excite him... well there's no reason to mess with the classics it thought... with a little twist of course.
A dark red and green portal opened up and two imposing figures stood there, a huge burly biker version of Santa with his arms around the waist of a busty woman with killer legs and long snowy white hair... her face in a rather haughty sneer, she was dressed in a set of dark green leather dominatrix gear.
"It's been so long since we've been summoned." the man said.
"MMM... yeah baby... but I hope it means that we get to punish those naughty heroes again." the woman purrs
"Yeah, that's what you're here for... go make the villains holidays happy and punish the heroes." the entity said.
"Ah so you're the uh... dude, that summoned us." The man said.
"Uh... I'm more of a nebulous ungendered force of darkness... but yes." the entity responded.
"Whatever, dude. You want Atnas and Mistress Klaus to make merry... just point us in the direction." Atnas said taking a drink from a can that seemingly came out of nowhere.
"yeah, just go that way." the entity said opening a doorway to the combined Marvel and DC universe.
"We should probably split up for this baby..." Mistress Klaus said giving her husband a peck on the cheek "want to place a bet on which of us makes the most merry?"
"Well I wouldn't want to rub it in your face." Atnas said.
"Please darling, I've been making skanks squeal for centuries before I met you." the dominatrix says with a smile.
"Oh you think you can beat the master of merry? You are so on lady." Atnas said as the duo enter the portal.
