The four X-Men panted heavily. They had been chasing the shadowy figure across rooftops for almost fifteen minutes and it seemed she never tired. They had followed their mysterious figure into an abandoned apartment building in the Bronx. It was dark inside, messy; furniture was scattered, shredded, and toppled. Paper had blown in through the cracked windows and littered the floor. Old beer bottles and rocks rolled around in the gentle evening wind. The lights from the street shone in through the cracked windows and cast a soft light on the floor.
"Eyes open." Scott Summers warned. He adjusted his goggles to a stun setting. They weren't here to kill their target, they weren't even here to fight. If she insisted on a fight, though, she'd get it.
Next to Scott was his wife Jean Grey. The fiery mutant with brilliant red hair stood at the ready, attempting to sense any movement in the building.
Rogue and Kitty stood shoulder-to-shoulder. The brunette in shades of blue stood looking warily. She had a sneaking suspicion of who their mysterious shadow figure was, but she needed to get close to find out for sure.
The white-streaked belle stood in her green and yellow uniform, brown trench coat billowing in the wind, her right glove in her left hand, leaving the pale flesh exposed and ready for battle.
For a moment there was complete silence in the apartment building other than the sound of the X-Men breathing. Something dropped in the middle of them and spun, spitting out smoke. Rogue tackled Kitty to one side while Jean and Scott backed away to the other. An arrow flew out of the smoke and stabbed Jean in the shoulder, letting out an electrical current and dropping her to the floor. Scott shouted her name and went to check on her. Three more arrows shot out of the smoke. Scott fired his beam of pure energy in return, but forgot that stun didn't cut through objects. The purple-tipped arrows imbedded in his flesh and rendered him unconscious alongside his wife.
Kitty and Rogue stood up, facing the smoke. An arrow flew out at Rogue, but the belle caught it with one hand. Another arrow flew out and the belle caught it again, dropping the other arrow. Smoke hissed out of the purple canister attached to the second arrow and Rogue collapsed to the ground unconscious.
Kitty braced her fists and phased slightly so that any object hurled at her would pass through. Nothing happened for a moment. Then a figure dropped out of the rafters and landed in front of Kitty.
She was Kitty's height, maybe a little taller. She wore skin-tight dark purple pants and black combat boots. Lighter purple plates of armor covered her thighs and calves. A white scarf hung from her waist. Her torso and arms were covered with the same dark purple fabric, with lighter purple armor plates covering her stomach, chest, and arms. She wore a dark purple hood and a black domino mask. A quiver hung on her back, a purple bow in her hands. The vigilante notched an arrow and aimed it at Kitty.
"You have failed this city!" she shouted, something altering her voice, and let the arrow fly.
