Okay, this one is a Warriors one-shot on the Four Horses of the Apocalypse, only...they're cats.
If you liked it, tell me if I should make a full fanfiction.
This is Lynxfrost, and have a happy reading!

The dark tortoiseshell padded forward, ears pressed flat on their skull and teeth bared in a questioning snarl.

Their yellow eyes shot glances at every rustle that the forest produced, and their tail lashed with both impatience and curiosity.

“Halt, Rookdawn,” a commanding -- and male -- voice said, his voice bouncing through the forest.

“I do not go by that name anymore,” the tortoiseshell replied stiffly.

“Then what is your name, if I may inquire?”

His voice held strong amounts of humor.

The tortoiseshell bared their teeth and their neck fur bristled, eyes narrowed in obvious anger.

“Do not insult me, you coward!” they snarled, eyes darting, scanning the trees for this cat.

“Oh, but I am not a coward, Rookdawn,” his voice meowed.

The tortoiseshell’s fur bristled.

“That is not my name, you coward!”

“But isn't it?”

The voice was a murmur this time, directly beside their ear.

Rookdawn jumped, paws flailing.

When they landed, they turned to the tomcat, the hate evident in their eyes and their lips, drawn to form a snarl.

There sat a short-furred black tomcat with eerily lit yellow eyes, appearing to glow as the moon's rays bounced off them. His tail was curled neatly over his paws.

“Then speak your name, child,” he meowed solemnly.

“My name…”

I was borne of death. I am a child of fear and destruction.

“My name is War.”

Okay, if you noticed, Rookdawn's gender is not revealed.
Well, they don't have one.
Rookdawn / War - brindled tortoiseshell with yellow eyes.
Death - short-furred black tomcat with yellow eyes.
