The Dresden Fillies

'The Dresden Fillies: Strange Friends (also found here) is a crossover fanfic by Psychicscubadiver, combining The Dresden Files and My Little Pony Friendship Is Magic. While traveling through the Nevernever, Harry Dresden finds himself chased by a pack of monsters and, after a Blind Jump between dimensions, winds up in Equestria. After the initial Fish Out of Water comedy, the story gets more serious—as it turns out, even a Sugar Bowl like Equestria may sometimes need the skills of one such as Harry.

A sequel False Masks has been recently started (also found here). Harry has been invited back to Equestria to be formally thanked for his actions in his previous trip. Unfortunately, an Ancient Tradition has gotten wind of his visit, and is certain that he represents the return of an Evil long since past.

Compare and contrast My Little Denarians.

"Trixie: I hope you all enjoyed that little glimmer of hope while it lasted, because those snakes have enough power in them to destroy anypony. Applejack: Good thing I ain’t just anypony, then. Rainbow Dash: Yeah. Equestria’s best flier isn’t gonna stop just because of some little bug zapper!"
 * Accidental Pervert: Harry and Pinkie Pie, thanks to Bob. It takes awhile for Pinkie (who doesn't understand these sorts of things at all) to explain to Twilight exactly what happened.
 * Animorphism: In False Masks, the Princesses want to award Harry a medal for his services in Strange Friends but first they have to make it so that he can walk around without anyone staring at him too hard. That means he has to go native. Naturally, he's a unicorn.
 * Alliteration: Harry get's chewed out by Twilight in this manner... He can't decide if it's frightening or just plain adorable
 * Badass: Harry, natch.

 * Batman Gambit: After failing to defeat, Twlight Sparkle appeals to her ego, tricking her into defeating herself.
 * Berserk Button: Pinkie becomes enraged when  Harry himself gets set off by women or children being threatened and

 * But You Screw One Goat!: Bob being Bob, when he finds out about Harry's misadventures from Strange Friends, suggests this route. Harry and Twilight shoot him down.
 * Note that since Twilight is a sentient being, it would be more of an Interspecies Romance - its just her equine appearance that makes the situation so awkward.
 * Carnivore Confusion: Harry is smart enough to avoid any blunders in this field but still faces a difficult moment when Rarity inquires about the origins of his leather coat.
 * Cerebus Syndrome: Not to the point that My Little Pony: Friendship Is Magic's Lighter and Softer feel is lost, but it is a crossover with The Dresden Files.
 * Curb Stomp Battle:
 * Cuteness Proximity: Hilariously, Dresden suffers this upon first meeting Twilight, saying that just seeing her makes him want to squeal like a little kid and hug her. He later describes Fluttershy as "weapons-grade adorable".
 * When he meets Luna, he's struck by how Adorkable and LOUD she is.
 * Death Glare: Before his soul gaze kicks in, Harry finds himself on the recieving end of Fluttershy's stare. It is not entirely clear who Twilight is saving when she makes the two break eye contact.
 * Determinator: They all take turns, but Rainbow Dash and Applejack take the cake when trying to diffuse the wall trap.

"“No. I don’t accept this.” I rolled my eyes and crossed my arms. “A wizard from another dimension happens to open a gateway into a magical land filled with talking ponies, and the first one he meets just happens to be the holder of an ancient and sacred power. Then those two and her friends, who also bear these powers, must rescue somebody she cares about from a jealous rival? Are you kidding me? If Kirby did that in Arcanos, I’d walk out! That’s the plot of a crappy fantasy novel!”"
 * Did We Just Have Tea with Cthulhu?: Twilight waking up from the Soulgaze in Fluttershy's house to find Fluttershy and Harry preparing for lunch.
 * Dueling Shows: With My Little Denarians.
 * Dulcinea Effect, Papa Wolf: You do realize this fanfic has Harry Dresden in it, right? Though perhaps a bit much since he has to be talked out of killing . Twice.
 * Twilight decides to play this up when she's trying to convince Harry to let her use her transformation spell on him.
 * Dungeon Crawling: After gaining new powers, builds what looks like a typical fairy tale castle...then succumbs to  paranoia and fills it with an absurd number of deadly traps, including:

 * The Walls Are Closing In / Shock and Awe
 * Dwindling Party: Invoked and defied. lures the group into her traps exactly for this purpose, but Harry and the Mane Six push their powers and skills to the limit to keep everypony alive.

 * The Smart Guy: Rarity, the party's illusionist.
 * The Chick: Pinkie, being Crazy Awesome.
 * The Heart: Fluttershy, Harry's secondary Morality Chain.
 * From Nobody to Nightmare:
 * Full-Body Disguise: Twilight uses an illusion spell to disguise Dresden as one of Celestia's guards when he's in public. In False Masks, she uses a spell to temporarily transform him into a pony.
 * Funny Aneurysm Moment: In-universe. Harry notices that Twilight's magic shield protects not just against kinetic force, but heat as well. He idly considers beefing up his own shield in the future, but apparently forgets, since "Strange Friends" takes place right before The Dresden Files novel Blood Rites,.
 * Genre Savvy: Harry and Pinkie.
 * Green-Eyed Monster: has a bit of this when she learns that
 * Twilight realizes she's a bit jealous when she discovers that Harry's magical power exceeds hers, but quickly gets over it.
 * Grey and Gray Morality: Something that Twilight didn't believe existed until Harry showed up.
 * HAD to Be Sharp: The ponies come to realize that Harry's world requires a certain degree of ruthlessness in order for one to survive as well as to enable good to win, and Luna applies this to humans as a whole, one of the reasons the Humans Are the Real Monsters trope is averted, as detailed below.
 * Handicapped Badass: By the time Harry returns to Equestria, he's hurt his hand.
 * Huge Guy, Tiny Girl: The only pony who comes even close to Harry in terms of height is Celestia.
 * Humans Are the Real Monsters: Nicely averted. There's the requisite shock over Dresden eating meat, but the Mane 6 grow to like him fairly easily. Luna and Celestia even say humanity seem to be a noble race, going by his example,
 * Humble Hero: As a result of the Soulgaze, Harry has a basic grasp of Twilight's personality. When she comments on him seeing something possibly untoward in her (he only sees her library and her photos and pictures of her friends and family and he finds it absolutely beautiful) putting aside the invasion of privacy, he reassures her that she has absolutely nothing to be ashamed of.

 * Innocent Innuendo: In False Masks, Twilight, unaware of most humans' social taboo on nudity, instructs Harry to strip down because she has a "surprise" for him (she wants to transform him into a unicorn for the duration of his stay in Equestria), causing Harry to react with a Spit Take and Bob with glee. Twilight is mortified to learn just what her comment sounded like to Harry and Bob.
 * Jerkass: During his second trip to Equestria, Harry brings Bob, a spirit of air and intellect that resides within a human skull. He remains quiet during Harry's meeting with Twilight until her Innocent Innuendo, at which point he speaks out, terrifying Spike out of his wits. After having a considerable time convincing Spike that Bob was not a ghost and they were not haunted, Bob promptly shouts "Boo!" at him once Spike worked up enough courage to approach the skull.
 * Knight in Sour Armor: Likewise with Harry, Twilight got an overview of his personality through the Soulgaze. Unlike Harry, she was terrified by what she saw. She saw him as a knight fighting a near endless horde of monsters, never once backing down. A knight who was in more danger of losing himself than losing to the horde.
 * Knight of Cerebus: Harry.
 * Even Heroes Have Heroes: Spike meeting Harry.
 * Lampshade Hanging: Harry, at every opportunity.
 * Knight of Cerebus: Harry.

"Bob: You didn’t see her face after you first turned into a pony. I'm surprised she wasn't drooling."
 * Leaning on the Fourth Wall: Pinkie, of course.
 * Lethal Harmless Powers
 * A telekinetic blast can be deadly when used to throw sharp objects. Also, the Elements of Harmony—they never cause direct harm, but that's still a lot of magic . Celestia is not amused.
 * Mind Over Manners: Protip: Don't stare into a wizard's eyes for too long. You'll regret it.
 * Mind Rape - The first thing Harry does after arriving in Equestria is accidentally soulgaze Twilight Sparkle.
 * also has this effect. It's damn creepy.
 * Mood Whiplash: Used extensively, but particularly when
 * Morality Chain: The ponies become this for Harry, especially Twilight and Fluttershy.
 * Mr. Fanservice: Harry becomes the pony equivalent of Tall, Dark and Handsome, thanks to Twilight's transformation spell. She has to remind herself not to gape. It amuses Bob.

""Everyone at that sorority was a consenting adult and the alcohol was just as much to blame as I was.""
 * Noodle Incident: Oh, Bob and your unceasing interest in the female fleshy form.


 * Not So Different: Rainbow Dash and Harry get off to a rocky start (though they quickly overcome their first impressions), which is humorous since Undying Loyalty (as well as a tendency to become very angry when their friends are threatened) is a defining character trait they both share.
 * Odd Friendship: Harry and Twilight, Harry and Fluttershy, Harry and Pinkie and Harry and Luna.
 * Out-of-Character Moment: As with main verse, having one of these alerts a person to the fact that Charm Person is being used on them.
 * Physical God: Harry meets Celestia and describes her as being as powerful and graceful as a Lady of the Fae Court, minus the scary. He is absolutely impressed when he learns that Twilight is her student. Luna for obvious reasons isn't quite as powerful but he can sense that she still is miles above him. They get on smashingly.
 * Power Glows: Harry's aura as a unicorn is red-orange. Makes sense considering how much he likes fire.
 * Red Oni, Blue Oni: Harry and Twilight.
 * Royals Who Actually Do Something: While everyone else is out adventuring to save the day, Celestia notices something is up, quickly returns home from Coltenhagen, places Canterlot on lockdown, searches her study for clues, interview all personnel on location and then leads a platoon of palace guards to Ponyville upon realizing that Twilight Sparkle is probably in danger. After the fight against, it's assumed that she personally brought the seven of them home and put them to bed since the palace guards and cooks still don't know what Harry is and that he's even there. Luna is the one with the maps of Earth and she even leads Harry back down the path towards his world.
 * Rule of Funny: Invoked by Pinkie Pie
 * Scars Are Forever: Inverted, much to Harry's surprise. Due to their nature, the ponies don't seem to scar at all.
 * Shipper on Deck: Bob wants to see Harry and Twilight get it on. Of course, Bob wants to see Harry and anything female and vaguely attractive get it on.
 * Shoot the Dog: Harry wants to do this to, but the Mane Six talk him out of it.
 * Shout-Out: Many, as is appropriate to Harry. He is quite unhappy that nopony gets them.
 * Slasher Smile: Trixie sports...a rather extreme one when she
 * Sleep Cute: After their ordeal, the ponies and Harry are taken to Canterlot where they sleep most of the day away on two extra-large mattresses, thanks to Harry's height. When he wakes up, Harry wishes like hell he had a camera.
 * Sociopathic Hero: Harry has to be reminded to tone down the violence several times.
 * Stealth Hi Bye: Harry is not easy to sneak up on so Pinkie doing just that quickly becomes a Running Gag. And then Luna does it too. Harry can't catch a break.
 * Taking the Bullet:
 * Trixie attacks Pinkie with high-speed shards of metal, but Rainbow Dash jumps in front of Pinkie just in time and takes the attack herself.
 * Tampering with Food and Drink: In chapter 5 of False Masks Things take a turn for the worse when  eats one. Fortunately, she realizes that there's something wrong with the candy and spits it out, though she still feels drowsy afterwards.
 * Time Skip: False Masks takes place after Blood Rites. Nearly a year has passed on Earth and two months have passed in Equestria.
 * Took a Level in Badass: Not that she wasn't badass already but Twilight manages to figure out how to use magic circles while Harry is gone.
 * Unskilled but Strong: A magic wall is described this way: 'It wasn't well-made by any standards, despite all of the power that had been poured into it, but it was so massive and durable that the sloppy construction hardly mattered.'
 * We Can Rule Together: Twilight Sparkle tries to talk  into giving up on The Dark Side and gets a   for her trouble.
 * What the Hell, Hero?: Delivered to Harry by Fluttershy, when he protects the Mane Six from a pair of manticores and nearly kills the two creatures through excessive force.
 * Becomes a Crowning Moment of Funny when Fluttershy talks the manticores down. He's completely thunderstruck that they listen to her scolding.
 * Harry very nearly returns the favor with a Silly Rabbit, Idealism Is for Kids in the form of a Soulgaze. Twilight, recognizing the danger signs, manages to alleviate the tension.
 * White-Haired Pretty Boy: Harry as a pony, to contrast his black main coat.
 * Who's on First?: Ponies keep saying that Harry isn't hairy.
 * Would Hurt a Child: out of a paranoid fear that Twilight has caught wind of her schemes. Too bad for  that threatening children is Harry Dresden's Berserk Button.
 * Year Inside, Hour Outside: When Harry returns to Equestria, only two months have passed. On Earth, it's been nearly a year. Since as far as Twilight knows, time dilation is more or less the same between the worlds, she doesn't get it. Harry assumes it's because of the Nevernever, but states that there is a basic balance, with one side's time going "faster" and the other going "slower" at certain points so that neither world gets too far ahead of the other time-wise.
 * You Shall Not Pass: Pinkie Pie pulls one off, holding back a swarm of venomous hornets so that the others can escape.
