Between Hallucinations and dreams, Spike's carnivorous dragon instincts start to arise and he tries to hide it from his friends. He is unsuccessful, as his will begins to falter.

Gore is for the first chapter but I doubt there will be any more.

Spike is distraught. The love of his life remains constantly out of his reach. His attempts at romance crash and burn like the Horsenburg airship. As the gala draws near, he enlists Blueblood to help in wooing Rarity once and for all. Little do they know that another mare already has her eye on Spike, not to mention a plan to snatch him up first. -Heart to Heart Sequel-

When Spike asked Twilight to help him create The Noble Dragon Code, he hoped a lot of things would happen.

Getting worshipped as a god by legions of theologically-inclined dragons wasn't really one of them but, hey, whattcha gonna do? Them's the breaks, kiddo.

This story is a sequel to The Golden Armor

It's more of a continuation than a sequel, but whatever.

Comet is the leader of Princess Celestia's personal guard. Angel is the leader of Princess Luna's.

Comet is awake during the day. Angel stays up all night.

Comet likes using a halberd. Angel excels at using claws.

Comet is a pegasus. Angel is a bat pony.

Together, they take on all the twists and turns life hands them. However, things don't always go as planned.

Spike has had it. It's not his fault the library is a shambles. In fact, he tried his very best to save it.

And now he's supposed to take the blame? Not this time! Until Twilight starts to fully appreciate his worth, Spike goes on strike!

He will not falter! He will not give in! He will stand his ground!
...if at the end of it all there is still some ground left to stand on.

Rumble's constantly told he's a cute colt, from most mares and even a few other colts. But, for the most part it's been that. Maybe it's been a passing comment, or maybe someone tried to pay him a compliment. And, for the most part, Rumble hasn't minded.

However, when his brother Thunderlane calls Flitter and Cloudchaser over one night to foalsit, Rumble begins to suspect something may be wrong, especially when the two adult pegasi mares begin going beyond just calling him cute. When mares across Ponyville start fawning over the colt, Rumble decides he simply needs the help of a unicorn to stop a strange form of innate pony magic not usually found in pegasi.

Going up to the roof for some fresh air after pulling and all-nighter, our "hero" makes the mistake of closing his eyes for a bit.
When he opens them again, he is no longer on the rooftop in Copenhagen he was expecting to be on... no he's somewhere very different, and extremely unfamiliar.
How will he react? How will the ponies react? Nothing is certain, except for one thing...

He never asked for this.

This story takes place about 8'ish years after the second season of MLP:FiM, the language of Equestria does not match any earth languages (that the main character knows of at least), and the human in question knows nothing of these ponies or the world of Equestria.
He emerges into Equestria on the roof of a building in Manehattan, not the Everfree, not Ponyville and certainly not one of the princesses' bedrooms in Canterlot Castle.

Oh! Spoilers in the comments and all that jazz, not gonna go into a whole spiel about it.

Sometimes, hardship might throw some light on what's really important, and it won't always be what you expect.

Indirect sequel to Melodious Desideratum.

After Princess Twilight is given the news that she must move much farther from their friend than she already had, Spike finds himself infuriated. The resulting argument is enough to force him to run away, but neither could have imagined how devastating it would be to their friendship. Now, six years later, Spike can't stop thinking about what he did that night and how dearly he wishes to take it back. So, after many sleepless nights, he decides to return to the friend he's long since abandoned, though when he arrives in Canterlot, Spike may have found more than just friendship.

Equestria's mafia is run by the most unlikely of gangsters.
