Batman groaned his head ached from where he had hit it on the desk. His eyes opened…where was he? He shook his head to clear his thoughts. He looked up and saw a woman with auburn hair with odd black streaks through it. With cat's ears and a tail. She looked liked a half human ginger tabby.

Katherine turned around from her tray of surgical tools and syringes filled with the chemical that changed Katherine into what she now was. It seemed fair that she would be doing this to him, it was his fault.

She had a manic grin on her face, she hated to admit it but she had begun to find this fun. Her test subjects would squirm. A mouse trapped in a cat's claws. Or a bat trapped. But he wasn't squirming or trying to escape, he didn't even smell of fear, not one bit.

"Katherine you don't have to do this." Batman said.

Katherine snarled and went to slap Batman to shut him up, but instead ended up scratching his face. She lifted her hand to inspect her nails, earlier they had been short and blunt but now they were long and sharp. More reactions with the chemicals that now flowed through her veins.

"Intriguing," she smirked. Her eyes the snapped back to them man strapped to the test chair. "You don't know what I've had to do, you don't even know me. It's Kat not Katherine but to you…" Her tail flicked from side to side violently. "It's Animi."

Katherine sniffed the air…fear? None. She smirked, that could change. Kat turned back to her array of needles and surgical tools.

"I didn't men for any of them to die Bat, they just weren't strong enough. But you are a different case. Well developed brain, strong muscular build an excellent test subject in my personal opinion." Kat called over her shoulder as she selected the right syringe for Batman's build, and the correct scalpel to cut through the fabric on his forearm.

Turning back to this mystery man in the cape and cowl she advanced on him. She grabbed his arm and proceeded to pull at the fabric trying to stretch it so she could begin to cut it with the scalpel. His pulse was increasing she could hear his heart rate getting faster, she could smell his scent changing to worry. Kat smirked and proceeded to cut through the fabric.

'I have to get out of here, who knows how the chemicals would react with my body?' Batman thought frantically as Kat began to cut through the fabric on his forearm. 'How long would it take until any changes were permanent? How long would it to make an antidote?' But what could he do? His arms were strapped firmly to the chair… but his legs weren't…

Kat cut through the last fibre of the cloth. She turned and smiled at Batman.

"This won't hurt." She grinned.

"But this will!" replied Batman

"What?" exclaimed Kat.

Suddenly there was a sharp pain in Kat's shins making her jump back and become unbalanced. She dropped the scalpel and fell forward as she tried to retrieve it from Batman's grasp.

"That was a cheap shot," groaned Kat.

Batman kicked her again, right to the ground and proceeded to saw through the belts strapping him to the chair with the scalpel.

Kat lay there on the floor of her laboratory with bruised shins and a splitting head ache as the Bat freed himself. She tried to get up but the rest of her body refused. She could already hear the police sirens coming this way. She'd lost. The Bat cut through the belts and stood up, looking down on Kat.

"You've ruined me Bat," Kat spat. "And I'll get you for it, someday."

Batman stooped down and hand cuffed her to the chair she had strapped him to. He left a small note beside her and swept out of the room right before the police burst in. she turned to read the note. All she could read of it was who it was addressed too. 'Commissioner Gordon' 'interesting' she thought to herself as she was hauled to her feet. It all happened so fast after that. She was unhand-cuffed and thrown in the back of a big white police van. She wasn't told where she was going or what was going to happen to her. Only 3 months in Gotham and this. No one would tell her what was going on. No one would even look at her. She sat down in the back of the police van.

"I'm a freak." She whispered to herself and then she drew her tail around herself for heat. "Just a freak."
