This story was born from a piece of an idea written some time ago. But like all the stories it got sidetracked from the supposedly original form.
No beta-read-ed. Not slash.
DISCLAIMER: Any names of non-ST or non-Doom characters are completely accidental (ever tried to type random letters on the keyboard, when you couldn't think of a name for character?) and have nothing to do with reality. I don't own Star Trek. I don't own Doom. I don't own characters of said movies. I don't even own the idea of Reaper!Bones :(
That's not how it was supposed to be, Derek thought running through the corridors constantly checking if he was followed. When a young, accomplished Derek Jensen was offered to lead a scientist team in genetics research he hadn't thought it'd be involving loosing his entire team and running for his life.
A few months back he, along with other five scientists, was transported to Mars. At first he had doubts; the old facility was practically falling apart before his eyes, but then he went inside. And he didn't want to ever leave. The part of facility, where his team was supposed to be working was well secured and turned into luxury science lab, equipped with the newest and most advanced devices. The supply run happened once in two weeks and besides that Derek, five scientists, married couple of engineers and three security officers were left alone. They all fell into routine and after some time it got boring.
So four days ago they decided to go and explore the rest of the facility.
Two days ago they found an old lab and seven vials of substance marked C-24.
A day ago Robers accidentally cut herself and spilled contents of the vial.
Twenty three hours ago they locked her in the quarantine cell.
Eighteen hours ago Nellie Robers escaped from her cell, killing Pavon and Jawne.
Sixteen hours ago they realized their bodies were missing.
Fifteen hours ago they listened through the comm as Jack Goegern and Stan Karoan were attacked, when Jack was trying to fix the power.
Ten hours ago they managed to kill one of the creatures.
Six hours ago they killed next monster, but they lost Isabelle Ioawy.
Five hours ago Ioawy still remained dead.
Two hours ago from eleven people on Mars there were only Derek and Trevor left.
Fifteen minutes ago Derek counted five monsters alive and three of his people dead without a trace of mutation.
Three minutes ago Derek managed to get enough power to send a distress signal.
Now he was running to the safest place he could think of.
He slowed down nearing the corner and cautiously peered into the next corridor. Empty. He started running again. Again checked if he was followed. Turned back to face forward and came face to face with a gray-skinned monster. He didn't even have the time to yell as the creature lunged at him.
McCoy growled at the unfortunate persons, that stood in his way to the transporter room and hadn't the time to scurry away to make a clear path for him. He barely restrained himself from tearing someone apart. Seriously, whose was this brilliant idea to beam down on Mars, to Olduvai, of all the places in the universe? He really, really needed to kill someone... or something.
McCoy was enjoying his last quiet hours on the Enterprise before they arrived on Earth for their shore leave. He didn't had any specific plans besides sleep, sleep and maybe some more sleep, but the way his Captain was behaving, McCoy was sure the kid had thought of something to do. Probably something idiotic and dangerous. And he'd want to drag the Doctor along. Not, that he minded... much. Making the kid figure out a new ways to convince him to go along with Jim's crazy ideas was something John enjoyed immensely. Nevertheless the Doctor wished, that his friend would be more careful. It was McCoy, who was immortal of the two. Not the other way around. Anyway, John really was looking forward to his shore leave. But then they just had to pick a distress signal from Firebat and rush to help them. McCoy spent hours in Sickbay on board the damaged ship putting back together her crew. And when he and his team were ready to beam back to Enterprise he found out from Scotty, who led the repair teams, that their home-ship left them to respond to another distress call. It was a good thing, that the corridor was partially trashed and full of pieces of junk, no one noticed a new hole in the wall. When they finally made it back to the Enterprise another disaster struck. McCoy was making his way to Sickbay, having heard from the Ensign operating the transporter, that some random red shirt from the away team had been hurt. Typical. What was with the red shirts and their high death rating? Reaper really should step up and teach them a real fight. Maybe he'll need to talk to Jim about that. After he tell him who he is. Which, if John have any say in this, will never happen. So, the entire idea it's just that, an idea. McCoy stumbled on air as he neared his domain, the familiar smell of mutated flesh hitting his enhanced senses. He froze, momentary overwhelmed with memories. It couldn't be. Not here. Not now. Not ever! John forced himself to move and he staggered into Sickbay. Sure enough in the center was the creature from his nightmares, the red scrapes of clothing still clinging to its skin, snarling at the present medical personnel, who scattered around in panic. It seemed, that the monster hadn't attacked yet. Thank God for small mercies. Or not. One of the nurses, brave, but also incredibly stupid started to advance slowly on the creature talking softly to it. Well, McCoy couldn't have that now. Could he?
"What the hell?" he exclaimed in perfect imitation of astonishment. The creature instantly zeroed on him. He could practically hear it processing the information: threat recognized, set to eliminate, just before it pounced on him. John let it happened, keeping it at enough distance so it wouldn't hurt him too much. But there was a slight problem. He didn't have a weapon. Fortunately a few seconds later two security guards barged in. They fired at the monster with their phasers. That didn't help much, what a surprise. The creature was momentary stunned. Just long enough for John to throw it in the abandoned corner. The monster shook its head and snarled around, seeking new prey. Meantime the medical crew had the sense to assemble into a group and now McCoy and the guards were between them and the former red shirt. The security kept firing at mutant, somewhat successfully making it to stay in place for a time, while Reaper scrambled to find something to kill the creature with. After another minute everything was said and done. McCoy even managed to get it look like a total, lucky accident. Then he proceed to yell at his staff to dispose of the body and every samples they managed to take and stormed to the bridge. There he learned from Sulu, that they lost contact with away team, of course Jim and Spock were part of the team because why the hell not?, when unexpectedly the part of the facility where they were at the moment went into quarantine mode. John left the bridge before he hurt someone.
So now McCoy found himself heading back to the transporter room, growling at the idiots in his way. He called on the way to Scotty, asking him to met him at his destination. Not wasting any time John asked the Chief of Engineering to display the map of Olduvai and the range of quarantine. Scotty gave him a curious look, but said nothing and proceed to show the schematics. It wasn't as bad as Reaper feared, but it wasn't good either. Jabbing a finger on the place, where McCoy knew was the armory with hopefully still working weapons, since the only weapons they had on board didn't work at all; and was outside the interference which prevented communication and transportation, John ordered Scotty to beam him there. The look on the Engineer face would be funny if the Doctor wasn't pissed off and in a hurry to get down to rescue his suicidal Captain and his equally suicidal First Officer. He treated Scotty with his special glare, which promised a future full of hypos and a lot of physical examinations and in the next moment he found himself in the armory. Reaper looked around, making sure he's alone and moved onto weapons, practically purring in contentment. Finally old, reliable, projectile guns! He choose a few, checking if they're still working. He found a bag and placed them in it along with the ammo for them, which sadly was not enough. Finally ready he slung the bag over his shoulder and raised the gun he left for himself. For a moment he mourned after the rifles his team was equipped with. McCoy took a deep breath and left the armory, setting a quick but quiet and careful peace, relaying on his senses to warn him. The scent of relatively fresh blood led him to the infirmary. John went inside carefully, but besides the bloody patches on the floor he didn't see anything. Well, that and a RRTS rifle. Someone got sloppy. With shining eyes he reached for it and winced as the bio-scanner activated, recognizing him as the authorized user, the mechanic voice unnaturally loud in his ears. And apparently not only his. He barely had time to check the weapon, when the monster appeared at the end of the corridor, charging at him in full speed.
"You know," Reaper drawled in annoyed tone, taking aim at the creature. "It's second time you interrupted my shore leave." Little did he know it was actually a third time; with the guy ending in the hospital after an accident and McCoy having to get back to work on his free weekend to patch him up. John pulled the trigger and killed the mutant with well placed bullets to the heart and head. He walked to the creature and shoot it again for good measure. One down, unknown number to go. He went to the lab next and with dismay discovered that the vials with C-24 disappeared. Reminding himself, that he needed the gun clutched in his hands he relaxed his grip slightly, so he didn't damage the weapon and continued further.
