Chapter Two (Pursuit and Faceoff):
Nightwing stood on top of the roof watching as Robin chased the masked caper on the adjacent building and failing miserably. With a sigh, he fired his grapple onto a stone gargoyle and flung himself forward to aid Robin. "Oracle," he reported, "I've got visual." He let go of the grapple and flipped backwards, catching a pole that hung from the side of another building. He leaped off the pole, cutting off the masked man.
The figure tried to veer to the left, but Nightwing had anticipated this. "Sorry, but not today." He threw a punch at him.
The figure evaded it easily. Batgirl somehow appeared beside him. How she got there without his knowing was a mystery to him, but this guy was gonna get it. Batgirl and Nightwing tagteaming a person? That was kill.
Nightwing aimed a roundhouse at the guy's neck, while Batgirl aimed a low kick at his knee. To his utmost surprise, the figure blocked his kick and tossed him to the side, knocking him off balance, and brought his knee up, evading Batgirl's kick effectively. This took about less than a second.
His eyes weren't visible, but you knew he was staring at Batgirl, who was the most formidable of the three. Robin came out of nowhere, trying to flying tackle the figure. He was caught off guard and staggered for a few moments, but came back strong. He relinquished Robin's grip on him and tossed him hard to the right, just off the building. Batgirl took a moment to decide, but ultimately went after Robin. Dick, who was already thinking the same thing, jumped off the building after Robin.
They looked up after they were safely on the ground. The figure was in mid-jump into the next building. When all seemed lost, a whirring noise came out of nowhere, and a jet black jet shaped like a bat followed the figure. Nightwing smiled. That bastard was in for it now.
-----------------------------------------------------------------------------------------------------------------------------------
Batman leaped off the jet where the man was waiting. "Who are you?" He said monotonously, but firm determination was there.
"It makes no difference who I am." The figure said. "But for now, you can call me Shadow," He smiled.
"I know you stole a rare Egyptian jewel in the Gotham museum last night. I want you to return it." Batman said.
"Too late. I did my job, I've already been compensated for my trouble." Shadow said.
"Come with me, I need to turn you in." Batman took a step forward.
"You do know I won't go willingly, right?" Batman could've sworn the face underneath the mask smiled.
"I thought as much," Batman kept his voice even. He aimed a jab at Shadow's face, who effectively dodged it and kicked him in the stomach. Batman's six pack and armor protected him. He didn't even wince. "That won't work against me."
"I can see that." Shadow said sarcastically. He jumped up and roundhoused Batman across the face. He was just about to finish Batman's heavy-breathing figure when he heard a commotion near the edge of the roof. "You got lucky, Bruce, until next time." He ran off and disappeared into the night.
