"We have you surrounded, come out with your hands *RATATATATATATATATA* " The police warning was interrupted by the inevitable gunfire. Cops hid behnd their cars, waiting for their moment to stop these criminals.
On the inside, the leader of the group said "Hold it! I think they get the message.". Another man came behind, dragging a bazooka!
It was placed at the window.
"We'll sneak out the back, Frank, if they try moving, you know what to do." The boss spoke. Just as Frank could nod though, an explosion of gas enveloped the room. While most of the guys coughed, some punches were heard.
The police looked blankly as they saw smoke come from he windows.
"Whos' there?! *cough* Come on out?!" The bossman said. Suddenly, he felt a tap from behind "Yoo-hoo.". As he turned, he felt a few punches to his gut. When he looked back, the smoke was clearing, and he saw that his men were all dazed.
"You think I'm scared of you Tweety bird?" he asked. "No, but what about him?" Robin pointed. Again the guy turned around, only this time he bumped big bat himself.

Later the criminals were being loaded into the cars. The dynamic duo watched from the roof of the building. "This felt familiar." Robin mentioned the stand off scenario. "Don't they all?" Batman responded before swinging off.
The night was routine for the crime fighting team. From purse snatchers, to serial killers, none were a match for them. Most of the guys they ran into actually broke down begging at the very sight of them, but some were dumb enough to think they cold beat them. Batman may only be human, but he's no push over.
Some were even dumb enough to run.
"We got a runner!" Robn said as he was cuffing the other two guys. Batman ran towards him.

Just as Batman was about use....that rope thing that wraps around your legs, the man was stopped dead in his tracks.
"Rednerrus." He heard some gibberish in a familiar voice. The guy then floated back to him, and in said "I surrender.".
As he knealed on the ground, Batman's suspicions were confirmed when a puff of smoke appeared, and revealed a familiar, not to mention beautiful face.

"Zatanna, thanks for the assist." He thanked the famous magician.
"No problem Bruce." Upon hearing that, he looked back at the man below him. "Don't worry, the spell rendered his senses dull." Zatanna explained.
Batman watched as she strutted forward "So, what's on your mind?". "What?" he asked. "Come on, I know that look in your eye." Zatanna had seen that look quite a few times when Bruce trained with her father, Zatarra the magician. That look meant his gears were turning. Then again, they usually were.

"Well I suppose I should warn you, Harley Quinn has become more dangerous." He said. "More dangerous? Now you're scaring me." Zatanna responded. "Then I'm sue you're not ready for this, Harley has gained the ability to eat people." Batman explained.
Being a master of the mystic arts, Zatanna had seen and heard a lot of strange things, but that made her jaw drop.
"Eat...people?" she was still scared. It was bad enough when mystical monsters could eat people, but in the hands of the most insane woman in Gotham, the whole city could be in danger.
"I know how it sounds, but thanks a substance called Chemical V, she can consume humans whole." Batman did his best to explain. "Now that is scary....you know, I think there's a spell that an do that." A random familiarity passed through Zanna's mind.
"Is there anthing your magic can't do?" Batman had to ask. "Yeah, get me a date with Paul Dini." she answered. "What?" Batman asked. "Nevermind." she said.

"Well, thanks for the warning Bruce, I'll keep my eyes open for a fat clown girl." she said. "I appreciate the help." Batman then hefted the droned out thief.
"Is there anything else I should know?" What Zatanna heard next, she was also not prepared for "She ate the Joker.".
That made even less sense than eating people. Harley had been Joker's 'technical' girl for years, now he was a digested mass in her intestines?
"I wonder how he feels about this?" she wondered. Out of the villains that had haunted Batman's night, the Joker had been the greatest horror. An incarnation of evil hiding behind a grin, and now suddenly he was gone. Batman had stated countless times that he refused to take a life, but Zatanna was positive he had been tempted by what Joker did. Now he was dead, at the hands of a now more lethal villainess. What did the Dark Knight think of all this?

"Don't worry, I'll be careful." she assured. "I hope so, Zanna." he left.
