C-24: The Truth about Mars by TreeOfLife1997 reviews
Leonard 'Bones' McCoy liked to think John 'Reaper' Grimm had died a long time ago. A name hidden deep in the past, just one of many names he had used over the years. It was his birth name. The name he had when the whole nightmare that is C-24 began. When a mission goes wrong, C-24 and the life of John 'Reaper' Grimm comes back to haunt him. He's not the only one with a fake name...

Slayers by Hawki reviews
Oneshot: Watching the cycle of Hell play out across dimensions, it occurred to the Seraph that perhaps there could be more than one Doom Slayer. Certainly there were mortals worthy of the mantle at least.

The Expendables VS Zombies by Wednesday1327 reviews
The Expendables have lived through a lotta crap, but never in their lifetime did any of them even consider a portal to Mars or zombies or the apocalypse happening in their lifetime. This came about from a dream with my OC Roxy B. meeting Gunner and there were zombies. Rated M for language, some sexual references, violence, gore. This is also posted @ AO3, under MissDawes.

The Waiting Game by Increasing Paranoia reviews
"Do you remember how I told you that I have two names?" Jim asks. "Vaguely," Bones finally responds. "I, also, have two names, Leonard," Spock tells the doctor. "It's the same name," Jim interrupts gleefully. "Uh, congrats?" McCoy asks more than states. "So, who's the lucky guy or gal?" "His name is John Grimm." Spock informs him. McCoy carefully avoids breaking his coffee mug.

A Careful Gamble by Increasing Paranoia reviews
"You hacked my file?" he asks and almost winces at his own tone. Jim blinks, breaking his gaze with some green alien girl and frowning at his friend. He hasn't heard this tone before – wouldn't have, because he's not hearing his best friend McCoy, he's hearing John Grimm and John Grimm is pissed.

A Different Kind of Nightmare by TreeOfLife1997 reviews
Promp from TFALokiwriter. AU. One day, Jim and Spock get on Bones' nerves, which makes him act a little less like 'Bones' and more like 'Reaper'. He wishes that he'd never been born out loud. After his shift, Bones returns to his quarters, exhausted and falls asleep and dreams about a reality where Leonard McCoy/John Grimm had never been born. Will Bones take back all that he said?

Nightmares and Broken Promises by Vex Vaudlain reviews
Nightmares. They were never a good sign, not for Leonard McCoy. When he had nightmares, it meant that the shit was about to hit the fan... This time, unfortunately, it might just spell the end for the Enterprise and her crew. Hell, what else was new? Reaper!McCoy, no pairings...yet.

Where you belong by TFALokiwriter reviews
Everyone has their 'where they belong' feeling. Just not on a science vessel. Reaper does not belong there. He can feel it in his bones. It doesn't help that Star Fleet knows and only recruits him for missions that they consider might explode into something more without the proper guidance. Just who the hell suggested him? Oh right. Chris.

A Mind Full of Fangs by Leylia Wolfe reviews
Massive rewrite of the movie. Keeping the characters. Fixing the plot. New villains. The UAC has military interests, but what does this matter to a tactical squad sent to enforce quarantine. Staff Sergeant John Grimm lives through hell made real. When he wakes up in military custody, they did something to his mind. Her face isn't real, but won't go away. They're setting hell free.

RRTS serving Star Fleet by TFALokiwriter
This is a story that begins with a scene that could have been added to 'After the red alert' at the end and Spock gets around to actually taking care of Kirk. Well, really, Spock finally makes the admission. Which of the two comes first? Naturally, it is the line "Damn it, Jim!" from John.

After the red alert by TFALokiwriter
I was messaged by a fan of the previous installment on who asked if I could make another chapter dealing on everyones reactions on Bones/Reapers death and talking about the idea actually started to make me think about the idea and want to write it. This starts out with a scene that was going to be written into Red alert but it was discarded.
