''Project: Sunflower'' is a [[WesternAnimation/MyLittlePonyFriendshipIsMagic My Little Pony: Friendship Is Magic]] fanfiction by Hoopy [=McGee=] and can be found [[http://www.fimfiction.net/story/5170/Project%3A-Sunflower here]].

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

When you finish the story, [[http://www.fimfiction.net/group/1563/Project-Harmonics a group]] has been started for authors to contribute stories set in the same universe, as it exists at the end of the story. Hoopy has started a [[http://www.fimfiction.net/story/49368/sunflower--side-projects side story]] that happens at the same time as "Project: Sunflower."

The long-awaited sequel, [[http://www.fimfiction.net/story/177431/project-sunflower-harmony Project Sunflower: Harmony]] is here at last! and from the look of the Foreshadowing, it's going to be pretty good!

!!Tropes present in this work:

* AdvancingWallOfDoom: The Black Tide serves as a seemingly unstoppable one, slowly consuming the surface of the Earth- and everything on it- meter by meter.
* AndIMustScream: Experienced by [[spoiler: Erin/Sunflower]], who can't even talk when [[spoiler: Malachite takes over her body.]]
* AnotherDimension: The whole point behind Project Harmonics is to find alternate worlds for humanity to migrate to.
* BackgroundMagicField: Equestria has one of these, and the Earth doesn't. This is part of how [[spoiler: Twilight figures out that Erin isn't Equestrian, as she lacks contact with Equestria's magical field]]
* BecameTheirOwnAntithesis: [[spoiler: Malachite]] used to live studying biology and saving lives, and later [[spoiler: merged himself with a swarm of creatures who feed on life-forces]]
* BecomingTheMask: Celestia notices that this may be happening to Erin/Sunflower towards the end of the story, as she is beginning to act more pony-like.
* BigDamnHeroes: Twilight and friends, when going up against the chimera
* BondCreatures: The [[spoiler: Fae Sprites]], in relation to [[spoiler: Malachite.]]
* CannotSpitItOut: Erin, to her Ponyville friends in regards to her true nature, due to pressure from Dr. Velchiek. [[spoiler: Literally unable to spit it out, once the Override was engaged.]]
* CutenessOverload: Erin's initial reaction to seeing the Equestrians for the first time. Also, every time she sees Marigold, her friend Meadowlark's little filly.
* {{Cyborg}}: Many of Erin's abilities come from her cybernetic implants, which include wireless communications, enhanced vision and hearing, and chemical sensors in her nose, lungs, mouth and digestive system. She also records everything she sees and hears to be relayed back to the humans overseeing the operation. There is also the [[spoiler: Override function, which Malachite manages to hack into at one point]]
* FalseFriend: Erin is afraid she is one of these to Twilight Sparkle and the other Ponyvillians. The longer she stays in town, the more guilt she feels regarding this.
* FantasticRacism: Several members of Celestia's Royal Counsel are dead-set against humanity coming to Equestria. Some of them even resign their positions and move away from Canterlot in protest.
* FishOutOfWater: Erin, once she gets to Equestria
* GroupHug: Several, during the course of the story.
* HeroesGoneFishing: Before the Mane 6 [[spoiler: go up against the Black Tide]], there's time for a quick shopping trip.
* HomeworldEvacuation: One is attempted after the Black Tide arrives and is proven to be nearly unstoppable. The humans use two methods: massive space arks (which are subsequently sabotaged by the "Earth-First" terrorist organization, which is bent on forcing the government to continue fighting rather than evacuate, which they call the coward's way out), and Project Harmonics, intended to find a suitable alternate dimension that humanity can move to. It instead leads them to Equestria and new allies, whose actions make humanity's evacuation of Earth no longer necessary.
* HordeOfAlienLocusts: The Black Tide.
** And the fae sprites, almost more literally. Although they prefer eating animals and people before vegetation (then each other).
* HumansAreGood: From the start, the focus of humanity is to open diplomatic relations with Equestria, rather than invasion, even though they know they'll invade if they have to in order to survive.
* IComeInPeace: Erin's whole motivation for taking up her mission, though her superiors forbid her from opening diplomatic relations on her own.
* IGaveMyWord: On a species-wide scale; a condition of the treaty between Earth and Equestria is that any other habitable worlds discovered by Project Harmonics would be open to ponies as well as humans for exploration and expansion. [[spoiler: When the Black Tide is defeated,]] a reporter suggests breaking this treaty; Robert Thomson, chair of the Committee of Human Survival, invokes this trope in a scathing reply.
* LivingLieDetector: Twilight Sparkle turns herself into one of these briefly, via magic, in order to question [[spoiler: Erin/Sunflower.]]
* ManaPotion: Twilight comes up with the idea of magic-storing jewelry, and the Arcanum (basically a collection of powerful unicorns) helps make it a reality.
* MindControlDevice: [[spoiler: Dr. Velchiek had some of Erin's implants reprogrammed so that he could administer mood-altering drugs, take control of her body (which Malachite uses to his advantage), and put her into a coma if she tries to talk about who she really is.]]
* MindRape: [[spoiler: What the Black Tide does to Malachite, and is implied also does to several others.]]
* {{Nanomachines}}: Used to turn Erin into a pony, the basis of the Black Tide... the story pretty much runs on nanomachines.
* MinnesotaNice: Erin and [[spoiler: her parents]] John and Lynne are from Minnesota, and are all very nice people, especially Lynne.
* NiceJobFixingItVillain: [[spoiler: The Black Tide, in an attempt to speed up its data gathering, strips away Malachite's fae sprites and absorbs bits of his mind, thus making it both much more dangerous, and vulnerable to the Elements of Harmony.]]
* NuclearOption: Nukes were used in an attempt to fight the Tide before the story took place. It didn't work.
* ThePowerOfTheSun: Celestia unleashes this twice. The first time [[spoiler: starts well, but ends with a devastating counter attack from the Black Tide]], and the second is [[spoiler: good, old-fashioned overkill against the Black Tide]]
* RoyalsWhoActuallyDoSomething: Both Celestia and Luna take a very active role in events.
* SuperStrength: Erin's pony body is "enhanced" by the human scientists, to be stronger and faster than a creature her size should be capable of. So, she's a little surprised when [[spoiler: she barely manages to keep up in a three-way race with Applejack and Rainbow Dash]]
* TailorMadePrison: Where we first find [[spoiler: The Thing in the Cave/Malachite]], though in this particular case, the prison [[spoiler: is self-made, due to an oversight by Malachite]]
* TakeThat: A huge one to TheConversionBureau.
-->" "What the hell are you talking about?" Robert asked, incredulous. "Are you insane? Where in the world did you get that idea? Even if we wanted to, we don't have the resources to turn seven billion humans into ponies. You, in the grey suit, you're up."
* TheReasonYouSuckSpeech: Given to a reporter saying that humans should break their treaty with Equestria right after they saved them.
* TwentyMinutesIntoTheFuture: The story begins in 2038
* WhiteAndGreyMorality: Both Earth and Equestrian societies have fundamentally sympathetic moral codes, and even exceptions like [[FantasticRacism Heart's Bloom]] or [[spoiler: Dr. Velchiek]] act out because of stress and understandable fear. And even The Thing in the Cave, [[spoiler: Malachite,]] doesn't like the idea of killing a sapient being, even by accident, although he's [[ObliviouslyEvil not very good at realizing what might be dangerous to other people]]. WordOfGod says that even the Black Tide isn't evil, just [[NonMaliciousMonster a repair module with some really bad programming.]]
