Xenith is a martial arts master

“Xenith’s been in the slave pits for years,”

...

I watched as the zebra stepped forward, moving up to Daff and lowering her head in what struck me as a sign of respect for her mortal opponent.

Daff didn’t see it that way. He saw an opportunity, and he took it. Spinning around, he delivered a brutal buck right into her neck. The zebra fell sprawling.

Daff turned, rearing up, lifting both hooves over the fallen zebra. Xenith rolled onto her back and kicked out with her hindhooves, planting them ferociously into the rearing earth pony’s exposed stomach. Daff fell, clutching his belly, coughing bloody spittle.

The zebra somersaulted onto her hooves.

Daff grunted and pushed himself back up, only for the zebra to crouch and spin on one forehoof, her outstretched hindlegs sweeping Daff’s legs out from under him. He went down again.

I stared, my jaw falling nearly to the ground. I watched the zebra’s fluid motions. She wasn’t brawling -- this was more of a fighting art form. I’d never seen anything like it.

“Heh. Looks like Fallen Caesar Style… not that I’m an expert,” Number Four noted with casual awe.

...

Daff made a move. He had managed to circle around so he was within range of Cinderblock’s corpse, with Xenith on the other side of the pool. Dashing over Cinderblock’s remains, he drew up his hindhooves…

BUCK! Cinderblock’s corpse flew behind him.

Sploosh! A wave of the green sludge surged towards Xenith. The zebra pinwheeled to the side in a maneuver I didn’t even think possible.

She charged towards Daff.

The large buck saw her coming and crouched down, holding his ground. He drove both hindhooves towards her in a powerful strike the moment she got within hoof’s reach.

But Xenith jumped. She leapt clean over Daffodil, striking the nape of his neck with a passing hoof. She landed in a graceful roll that ended with her back on her hooves, facing him.

Daff seemed frozen in place. He stared, unmoving.

“Paralyzing Hoof!” Number Four announced. “Now that’s definitely Fallen Caesar Style.”

She could paralyze a pony with a hoofstrike? How the hell was I supposed to fight against that?

Daff toppled over. Xenith trotted up to the fallen pony, her sad gaze looking into his wide and fearful eyes. The crowd began to chant and pound their hoofs. “Kill! Kill! Kill!”

Stern’s voice called out, bizarrely magnified. “Finish it!”

The zebra planted one hoof on Daff’s neck. She lowered her head, her muzzle lingering next to his ear a moment before she bit into his mane. She pulled her head back with a hard jerk. I heard Daff’s neck crack.

Xenith’s teeth let go of the dead pony’s mane. She trotted towards the center of the arena and waited for her next opponent. Me.

...

Xenith struck me with her forehooves, driving them into my wounded side. I heard and felt as my cracked rib broke and punctured into one of my lungs. I collapsed, sliding backwards from the force of the blow. The world swam as I struggled for air.

It was like she’d known just where to strike to cause the most injury. (As opposed to Daff, who had just known where to cause the most pain.)
