Nightwing knew there were dozens of different fighting styles. He had perfected 13 of them with another dozen well practiced. He knew capioera, Akido, karate, not to mention his own flares for twists, flips and leaps as an acrobat.

He had gone up against master assassins, aliens and mutants. He had nearly died twice the amount of times he had survived. He had been trained by the best of the world's fighters, Black Canary, Wildcat, Green Arrow and of course Batman himself.

But this woman?

She was different.

Not that he hadn't fought his fair share of deadly enemies, Lady Shiva, Deathstroke and Kobra. They had all been formidable, deadly adversaries.

However they were different then this woman.

She was short, skinny, muscular though and strong looking. She had short black hair, free flowing in the chilly night. Her skin was pale against the back kevlar tri weave she wore. Her outfit was simple and practical. A heart shaped corset with black pants and boots as well as elbow length gloves. A cloak was slung around her shoulders, draping across the rooftop. Nightwing would see her eyes, aside from the fact that she had a diamond mask over them, just as he did himself

"You are good," She drawled, "I heard the stories, but my God, you are incredible!"

"Thanks," he said, his voice deeper thanks to the voice modulator, "You're not half bad yourself."

Nightwing didn't say it often.

He truly meant it. The woman had skill, talent, training.

Yet he had never seen her before in his life. In his 10 years as a hero, both as Robin and Nightwing, he thought he had met every major player in the game.

Yet here this woman stood, able to match his moves.

He wasn't sure where she stood in the world as a hero or a villain, but to see her leaping fearlessly over rooftops and ready for battle. She carried no weapons, only her fists and her feet.

They were deadly enough on their own.

She had swung, her arms long and agile, her body twisting around his. Her legs were strong, striking him fiercely. She was flexible, skilled in acrobatics like himself, she used her surroundings just as he did, bouncing off air units and around antenna poles. Nightwing had never seen someone use such a unique blend of acrobatics and fighting styles.

Not unless he watched his own videos of training in Mount Justice or the Batcave.

"So I gotta ask," He asked, "Why haven't I seen you around? You're pretty good."

"Maybe cause I didn't wanna be seen," She smirked.

"It's hard to hide when your jumping cross town. And not in a car or a train."

"I took the train," She pointed out, "I just didn't sit on the inside. Or at all."

Nightwing raised an eyebrow and she laughed.

"Try standing on a train going 80 miles an hour in heels. It's so much fun!"

Nightwing cracked a smile. He had done that. Multiple times. In fact the first time he rode the E Line he scratched Robin into the metal with a batarang.

Batman was not amused.

But then again, when was he ever.

"So what are you doing in Bludhaven?"

"I thought this was still Gotham," She countered.

"Past the bridge," Nightwing corrected, "That's city limits. I'm guessing you're new in town."

"Really," She snickered, "With all the bats around I thought I would escape your notice and learn my way around."

"Not that many of us," He laughed, "Lots of copy cats, but not all pros."

"But I am," She smiled.

"I can see that," He nodded, "The real question is are you here for profit or justice?"

"Profit is tempting. Bludhaven is cheap, but it's still the city. But no. I'm here for you."
"Trying to kill me?" Nightwing chuckled, "You're not doing a very good job. You didn't even bring a gun."

"I wouldn't need a gun," She countered, "Even if that was the reason. Which it's not. No, I had to test myself against the brightest and bravest."

"Another Desparo," He groaned to himself, "Great."

"Desparo?" She asked, "That's an unusual Bat name."

Nightwing laughed.

"No, not a Bat. Just an alien nut case."

"Aren't they all?" She shrugged, "Well most. The Martian and Superman are cool. Those Reach guys? Not so much."

"I can agree with that," He laughed.

"Thanks for the practice though," She said as she fingered something in her wrist, "But I gotta get going."

"Not robbing jewelry store are we?" He asked.

"No, no," She shook her head, with a smile, "I'm not Catwoman."

"So what do I call you?"

She had turned to jump over the roof, but looked back at him, smiling seductively.

"How about Dancer?"

Before Nightwing could reply she laughed, leaping out into the cold wind. Nightwing rushed over, waiting to see a grapple line.

Instead the woman rolled onto a building and spinning upwards, using parkour to travel up a building's balconies. Her movements were fluid, soft and supple, yet at the same time, strong and well practiced. She arched her body just as she did when they fought, using artistic and lengthy stretches.

Her fingers graced the edges and her toes hardly stayed still.

Just as Nightwing was about to follow his com beeped.

"Nightwing report," Batman's gruff voice sounded, "Anything of interest?"

Nightwing watched silently as Dancer dived beyond another rooftop, shrinking into the distance.

"Nightwing?"

"No," He said, clicking the talk function, "Nothing tonight."

"Get over to 5th and Broadway, Batgirl needs help taking down Penguin and Black Mask. Batman out."

"On it, Nightwing out," He said.
