This is just a teaser bit, not beta'd on anyone. Just something that popped in my head. Honestly its the first thing I have had pop in my head in a while. I own nothing but the bit of story to it. Going for the Suicide Squad look and maybe mix Suicide Squad with Batman the Animated Series feel for the characters.

An extremely pale young woman with striking blue eyes, blonde hair, glasses, and different air about her strode past the Behavioral Analysis Unit (BAU) bullpen. She wore a simple outfit consisting of black dress pants and a tight fitted red shirt. Her heels clicked as she followed Chief Erin Strauss to the office of Aaron Hotchner. She glanced around taking in the team staring at her. David Rossi, Penelope Garcia, Derek Morgan, Jenifer "JJ" Jareau, Dr. Spencer Reid, and Emily Prentis. Not too long-ago Jason Gideon had left them and Rossi had taken his place. So, they weren't as cohesive as they could be.

The woman was the infamous Harley Quinn, girlfriend and lover to the Joker. However, the last time the Joker kicked her out she ended up caught. She agreed to testify against her Puddin's men to avoid Amanda "The Wall" Waller. She absolutely refused to talk about the Joker other than to defend him. So here she was in witness protection, as most of the persons in the system believed the Joker would kill her for betraying his men. And where better to stick her than the BAU, she was a Psychiatrist and perhaps knew the criminal mind better than anyone else. After all, she had been a criminal. All of this would be disclosed to Agent Hotchner and he would introduce her to the team as Harley Kaufman, a new agent who would be joining their team. What Harley didn't know was she was sent to the BAU for Agent Hotchner to profile her make sure her change of heart was true, and perhaps figure out how to turn her against the Joker.

After Hotch, as he preferred to be called, was told about the blonde woman before him, he sat there shell shocked. The Joker was a danger to everyone and judging by the fire in Harley's eyes so too might she be a danger to everyone. Was she truly on the up and up or would they be forced to imprison her? Only time would tell. But would they have the time?

Meanwhile

"HARLEY!" The Joker yelled dragging out her name as he stormed through their hideout. "Where is she?!"

"You threw her out boss..." one of his henchmen answered. Perhaps not the smartest thing the man had done.

The Joker turned his gaze to the man and shot him, "She is usually back by now!"

Another man, braver than the rest, spoke up, "She seemed more upset by this one boss. Or maybe she's off with Ivy or... The wall has her..."

"Then find her! I don't care what it takes or who you have to kill!" he yelled turning his snarling face towards the man. "Find her or you are all dead!"

He laughed, "No better yet, find her or I'll be mailing you bit by bit... one by one... to each other and then..." He paused for affect then growled out, "once all of you are dead... I'll mail ya to your mothers!"

Honestly I don't know if I should continue orjust let this be a small one shot. I have like no creative juices lately.
