Requested by Paint the Cat! Sorry if it's not what you wanted/expected. I don't really know what the Malevolent/Rebellion are, but I did my best :)
"Well. Look at the little kitty. Was it hard for you to get to guts to show up?" Outlaw taunted her little sister.
"Shut up. We all know who's stronger." Kynia stepped forward, and without any warning, jumped at her sister, slashing her ear.
Outlaw laughed. "Is that the best you can do? I knew you... er, what's it called again? Ah, yes. I knew you Rebellion cats were weak, but not this weak."
"The Rebellion is strong!" yowled Kynia. "And the Malevolent is filled with cruel, heartless fools who follow your every order.
"But we've survived this long. The Rebellion hasn't been around nearly that long. And you're about ready to disband, hm? Lots a tension, huh?"
The two sisters faced each other, years of hate and tension bubbling up. The Malevolent were a group of alley cats who would kill or maul without hesitation. A while ago, some other cats of the same group had had enough of the cruelty of the Malevolent, and went to make a new group of cats, called the Rebellion. And it just so happened that the two leaders of the groups were sisters.
And now, they were meeting, face to face, at the train tracks. The same train tracks that, not even a moon ago, Kynia had thrown Outlaw into, costing the Malevolent leader her tail.
Kynia scowled and sprang at her sister. Outlaw quickly sidestepped, extending her claws and slashing her sister's ragged black pelt. Kynia gritted her teeth and spun around, grabbing Outlaw's still-sensitive stub of a tail. Outlaw shrieked and lunged, her claws slicing at Kynia's back, her belly, her legs. The black she-cat grunted, blood dripping from her various scratches.
"Is that all you've got?" teased Outlaw. Kynia yelled in defiance and jumped for Outlaw's back, but the Malevolent leader was quick. She rolled away and, taking advantage of Kynia's momentary confusion, slashed at her sister's belly. Kynia slumped to ground, gritting her teeth. Blood poured from her wound, painting the earth beneath her dark red. She darted a paw out, nicking Outlaw's ear. Hissing, Outlaw scrambled backwards, turning slightly while doing so.
Then Outlaw saw the train.
Grinning in triumph, Outlaw ran around her sister and tackled her from behind, pushing her onto the train tracks. Kynia fought valiantly, but it was no use; Outlaw was pushing Kynia's head against the tracks. Her hind legs were on Kynia's stomach, the claws digging into her and drawing blood.
Kynia gasped with pain and kicked out wildly. Most of them missed, but one hit Outlaw's stomach. Instinctively releasing Kynia, Outlaw jumped back. Kynia slid to the side and pinned Outlaw down against the tracks. Seeing the train, Kynia scooted back.
The train rolled right over Outlaw.
The wheels crushed her soft, tender body, over and over. Outlaw was screaming and crying and begging for it all to be over. The tabby she-cat could feel her life ebbing away with each hit from the train. She was battered and bloody as she tried to pull herself off of the tracks.
Outlaw only managed to get her head out from the tracks. Amazingly, she was still alive. Blood was all over her face. Kynia could see the rest of her body being continually plowed into by the train.
Outlaw panted, a waterfall of blood coming out of her mouth. "I... uhh." She closed her eyes, and then opened them, before saying, "Remember when you pushed me into the tracks some time ago? And my tail got caught and was ripped off?
"Remember when you betrayed me here?"
Kynia watched, emotionless, as her sister struggled against the train, in obvious pain, and then died.
Some time later the train finally finished crossing the tracks. Kynia padded closer, slightly curious as to what her sister looked like.
Outlaw's face was bad enough. She had an obvious cracked skull and one of her eyes was closed, sticky with blood and fluid. Her mouth was wide open, blood still flowing out.
The rest of her body was a nightmare. Blood all over the tracks, gashes all over her body, her limbs twisted and disfigured and slick with blood.
Kynia dragged her sister's body from the tracks and dropped it right next to a tree. Then she left. She didn't look back.
Okay. That was a pretty crappy and short chapter. Not to mention gory. Sorry about that.
