[[http://www.fanfiction.net/s/6933825/1/Pony_Space Pony Space]] is a crossover fanfic between ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' and Franchise/DeadSpace.

After an [[TomeOfEldritchLore ancient book]] is stolen from the royal treasury in Canterlot, An attempt to prepare for the worst by twilight and luna, ends with the accidental summoning of engineer and Necromorph slayer, Isaac Clarke into Equestria. Now the two of them must find a way to work together while they try to stop the ponies who seek to resurrect the Marker.

!!Pony Space contains the following tropes::

* BreatherEpisode: chapter 9, which comes right after [[spoiler:Fluttershy and Ditzy being kidnapped]]. It ends with a [[spoiler: WhamLine.]]
* EyeScream: [[spoiler:Ditzy]]
* FeatherFingers: {{Justified|Trope}} in that it's low-level telekinesis.
* LighterAndSofter: For the VideoGame/DeadSpace side. The story is about stopping the marker outbreak rather than surviving, necromorphs rarely show up, and much of MLP's light-hearted humor is kept.
** Later chapters subvert this becoming much darker in tone.
* MacGyvering: Isaac builds a new plasma cutter out of parts from a oven, an electric sewing machine, and an stereo system.
* MadeOfIron: Celestia. She [[spoiler:doesn't die from a bomb designed specifically to kill her because she wasn't within touching distance.]]
* NoHoldsBarredBeatdown: Rarity delivers one to one of diamond dog guards in chapter 18 while giving him an AndThisIsFor speech. [[spoiler: She accidentally kills him in the process.]]
* RageAgainstTheReflection: Isaac does this after seeing his new pegasus form in the mirror, [[spoiler: and then hallucinating getting attacked and taunted by his own reflection]]
* SanitySlippage: [[ShellShockedVeteran Isaac]], of course. [[spoiler:Rainbow Dash starts seeing marker apparitions and hearing voices later on.]]
* ShipTease: Isaac with both Twilight and Applejack. Lampshaded by Marker!Kendra, much to Isaac's annoyance.
* ShooOutTheClowns: Isaac attempts this on the mane six, it doesn't work, in fact seeing the horrible things the Marker Cult has done just makes them want to help more.
* WhamEpisode: Chapter 10. [[spoiler: Canterlot castle is bombed in an attempt to kill Celestia. Dash gets attacked by a pack of stalkers and is now seeing marker apparitions.]]
** WhamLine: At the end of chapter 9.
--> Canterlot was [[spoiler:burning]].
