This is a story from the 2005 film Doom. This is a twincest fic between Sam and John Grimm. A plasma transfusion causes her to develop mating instincts from those humans so long ago. John instinctively responds like a typical neanderthal and smut ensues.

Lex 'Midnight' Archer joins the RRTS 6. For 2 years she ate, fought, and bled with her unit, growing close with most, especially the reserved John 'Reaper' Grimm. One mission goes horribly wrong, triggering a *SERIES of EVENTS* where she and John rely on each other to survive. [Reaper X OC][Future Crossovers][Multi-Volume Series in 1 Story][Volume 1 Complete][Movie(s)-Centric]

Something has gone terribly wrong at a remote scientific research station on Ryushi. All research has ceased. Communication has failed. And the messages that do get through are less than comforting. A frantic call for help from the remote research station sends everything into a Level 5 Breach Emergency and the only souls allowed in or out are the UNSC Special Operations Task Force

John Grimm - aka Reaper - and his sister Sam are sent to a small secluded Pacific Island for an unspecified amount of time for enforced R&R while the powers that be clean up the mess that was 'The Ark' and John can come to terms with his new found 'powers' thanks to Sam injecting him with C24. What they find in the jungle however, brings a new nightmare to life.

John Grimm is a disciplined, by-the-book Marine. Unwavering nerves, brave in the face of danger, obeys every command. Before Sgt Grimm joined the Double-R.T.S., he met his match in a Marine Instructor for a course he was assigned. Will CPL John Grimm resist the beauty of CPL Dylan Devreaux? Or will he cave to her sexy, aggressive, kick-ass-take-names charm?

Annihilation Oneshot: Life in Mars City was pretty tedious. But it was much better than being stationed on one of the planet's moons.

Part 3 of 3. After the events on Olduvai John, Sam and Maddie being the only survivors, have to deal with everything from reports to grief. But something happens once they get back to the surface that changes everything they thought could be possible.

The RRTS gets a new soldier, her past has been rough, she doesn't take crap from anyone, but what happens when one catches her attention. What if they soon can't stay away from one another, what if one mission turns deadly.

No place is safe anymore, not when the mutation has spread. Those that have turned rule the earth with a savage thirst for blood, and those that survived have fled the plane. A new weapon may be able to turn the tides of this war and end the terror caused by C24. The one question is, should it? But there is something to fear, something unseen...till now. Book 3 of Doom Saga.

The research facility on Olduvia has been compromised can the memebers of the RRTS help stop this deadly force and at what cost ? My take on the Doom 2005 movie, some characters will be changed and the plot will differ

Hell is a place where your worst fears come to life. Hell is the place where everything and everyone you love dies. Hell is Olduvai, and I'm trapped here. JohnxOC fic. Rated T for swearing.

'Destroy the bio-hazard and any evidence of it. If all else fails, blow the facility' If only it was that easy. Ex marine and special operative Valkery Syn gets offered the freedom she has always wanted, but there is a price. A mission that she can't fail, along side her old rivals in RRTS unit 6. Be afraid of the dark, be very afraid. (John X OC) (Reconstructed) (Movie x Doom3)

After the events at Olduvia John is shipped to a new station. A station that doesn't seem right. Exactly how long have they been here?

Mars held demons for us all, there were days when I actually could put it all behind me. When I could almost ignore the nightmares that I saw every time I closed my eyes. That all changed when the call came. I thought I could make peace with my past, I thought I could end that chapter of my life. Hell is very real and it has awakened on Mars. God help us all. John/OC movieverse

title: Ghosts. (Russian...hint hint!) Hell is not all fire and brimstone. It isn't a burning pit of flames and smoke. Hell is cold and dark. It is demons living within the darkness, waiting, preying on you. They feed on your fear, thrive on it, and use it against you. For the living; Hell is Olduvai. Book 2 of Doom Saga

John wanted more for Sam than this.

RRTS is about to face an evil they've never seen before. Same story, same team, but one extra kickass member. rated for massive gore and language. Book 1 of Doom Saga

From her transfer, to the Russian mission that nearly took her life. The story of Vera Dimitrov: Mira, is finally released, follow the ass kicking, short tempered, Russian soldier through missions that made her one hell of a valuable member of RRTS 6. And made her John Grimm's closest friend. Rated for cussing; Russian, English, and French. prequel to Doom: Reprise UNDER EDITING

Karina never understood her family. Not until she got a job on Mars, digging up human remains and stutying them to help human back on Earth. After the Mars base goes to hell, she is left to discover a secret that will unlock the lies her family had told her. GrimmXOFC

John 'Reaper' Grimm begins to struggle with his growing strength and animalistic behavior as command of the RRTS is given to him. Now he as to deal with new people! John/OC Originally a One-Shot called His Afterlife. T rated beginning, might change over time.

Sam hasn't seen John in over two years, but it figures he'd show up when least expected.

A one-shot about John's thoughts soon after they return from Mars.

A collection of oneshots featuring Grimm and one of my own characters. For now the rating will be T. Might change later as story progresses. Grimm/OC

My name is Anne Black and my best friend is Sam when we went to retrieve research data we weren't prepared for what waited for us while doing it. John/Oc

Chromosome 24 was not bioengineered from scratch. It was copied from the genetic profile of a pre-existing race; a species which swore never to interact with humans again. Now, with portents of the Doom repeating its horrible history, one among that race must aid the humans destined to face the demons of their past. Reaper/OC. Rating for future violence, gore, and adult themes.
