<Lt. Cmdr. Mortimer, U.S.S. Lafayette Holodeck>

Mortimer steps onto the holodeck.

Klingon or Romulan opponent? Beating up Romulans is more enjoyable, but a Klingon would be more of a challenge, and right now I need something to take my mind off everything. Seeing a Romulan would just make things worse.

"Computer. Simulate outdoor terrain on the Klingon homeworld."

A rocky area covered in small patches of foliage appears.

"Simulate a Klingon warrior. Unarmed"

A burly Klingon materialises.

"Program the Klingon warrior to the Klingon equivalent of my unarmed combat rating"

Mortimer opens a panel on his artificial arm, and turns the power down to standard human strength levels.

"Run program"

Mortimer takes a swing at the Klingon, who blocks it, laughs and responds with a chop to the side of the neck.
Mortimer goes down, and the Klingon kicks him in the face, before picking him up and throwing him five metres away. 

"Ooof"

Mortimer gets up and runs at the Klingon, who ducks, grabbing Mortimers legs and throwing him over his shoulder. The Klingon backhands Mortimer's face, then clenches his hands together in a blow to his head, knocking him to the ground. The Klingon picks up a nearby rock, and launches himself at Mortimer.

Mortimer rolls to one side, spitting blood. Coming in low, he elbows the Klingon in the stomach, then rotates his forearm at the elbow, bringing his fist to the Klingon's mouth. Grabbing the Klingon's head, he pulls it down while bringing up his knee, and hears the satisfying crunch as he breaks his nose. The Klingon swings wildly in anger, and knocks him away. Mortimer gets up just as the Klingon's boot hits him in the stomach. He responds by chopping the Klingon in the throat.

Pulling back, Mortimer turns through 180 degrees and kicks the Klingon in the teeth, then crouches and runs in low, clipping the Klingons legs from under him. The Klingon grunts as he hits the floor. Mortimer brings back his arm and delivers a blow to the Klingon's temple with the palm of his hand. The Klingon responds by swinging his leg across, taking Mortimer down. The Klingon gets back up, and grabs Mortimers right arm (the real one), twisting it behind his back. Crying out in pain, Mortimer grabs at the ground with his other hand, and throws dust into the Klingon's eyes.

He grabs the Klingon's arm, turns, and crouches, throwing the Klingon over his shoulder. Picking him up, he delivers a series of rabbit punches to the Klingon's broken nose, then draws back and throws himself at the Klingon's stomach. The Klingon goes down with Mortimer on top, then kicks Mortimer between the legs.

Mortimer's eyes cross for a second, and he falls backward. The Klingon comes over and starts kicking him in the side and the head.

Mortimer tries to roll away, but the Klingon is too quick. he picks him up horizontally, and drops him, bringing his knee into Mortimer's back. Mortimer collapses to the ground in pain.

The Klingon jumps and brings his elbow down on Mortimer's face. Hard. Mortimer howls in pain, and rolls backward. The Klingon starts to rain blows down on Mortimer, who uses his artificial arm to protect himself. Seeing the opportinity, Mortimer throws himself over an outcrop, and hits the ground two meters below.

As his opponent makes the same jump, Mortimer brings his fist up into the Klingon's stomach, raises his left arm above his head, and brings his elbow down onto the Klingons ridged forehead.

He rolls forward, past the Klingon, and gets back on his feet behind him. He stamps on the back of the Klingon's knee, causing him to collapse to the ground. Grabbing the Klingon's head, he pounds it on a nearby rock. The Klingon struggles for a few seconds, but soon collapses unconscious.

Mortimer falls to the ground himself, gasping for breath.

"Computer. (gasp) Revive... opponent."

The Klingon slowly gets back to his feet, with a smile on his damaged face. (Well, only a Klingon would recognise it as a smile)

"Same time next week."

"Definately. I needed a good workout to get my mind sorted."

"Computer. End simulation and save as Program Klingon-Combat-One"
