My Little Avengers

A crossover between My Little Pony Friendship Is Magic and The Mighty Thor, written by Koolerkid.

It's Big Macintosh's birthday! As he goes for a hike, an Ursa Minor chases him into a cave, trapping him there. Inside, he finds a stick and transforms into The Mighty Thor!

It eventually expands into a full-blown Avengers story, with Captain Equestria, Iron Pony and Firebird as they face off against Loki and his apprentice, Trixie!

It can be found here.

The Fanfic contains examples of:
""I'm sorry I followed you home and broke into your house and stole your stuff and ate the last of your pancakes-""
 * Ten-Minute Retirement:
 * All Your Base Are Belong to Us: Loki briefly sets up shop in the Avengers mansion for his confrontation with Thor at the conclusion of his plan (see Darkest Hour below), before moving on and occupying the royal palace.
 * Arch Enemy: Thor and Loki, as per the mythology and comic canon.
 * Oddly subverted, however, with Trixie and Twilight Sparkle -- Trixie describes Twilight as her "nemesis" at one point, but after that it's never mentioned again. Heck, the two don't even interact at all in the story (aided greatly by Twilight barely even being in the story).
 * Also subverted with the Dark Avengers; they each apparently view themselves as the archenemies of their Avenger counterparts, but aside from the Thor/Loki fight, the Final Battle doesn't involve any of the counterparts pairing off (which was the Avengers' plan).
 * Arson, Murder, and Jaywalking: Pinkie steals Mjolnir from Big Mac in order to get him alone and talk to him about it. Afterwards, she apologizes for it:

""Sorry about sneaking into your room and waking you up and scaring you and eating your last pie...""
 * And then she does it again when she breaks into Spitfire's apartment to talk with her:

""I SAY THEE NAY!""
 * Bastard Understudy:
 * Because Destiny Says So: The Red Skull believes that some people (namely him) are naturally superior, and that it is their destiny to rule over others. During their fight, Iron Pony basically tells him to take that theory and shove it.
 * Berserk Button: As Fin Fang Foom found out the hard way, you do not threaten Big Mac's family.
 * Big Bad: Loki the Magnificent
 * Big Damn Heroes: Fittingly, Thor gets one early on, when he saves Rainbow Dash from the Wrecker, just as the latter is about to kill her.

""Loki! I would have words with thee!""
 * Book Ends: The story begins and ends on Big Mac's birthday.
 * The Brute: The Wrecker and the Juggernaut.
 * One could probably also add Fin Fang Foom to this list as well.
 * Cain and Abel: Loki and Thor, of course.
 * The Cameo:, of all people, gets one as a pony version of himself.
 * Chekhov's Gun: At first, it seems the reveal that  is just a convenient way for Pinkie to know everything about Thor. Then it turns out that.
 * The Chessmaster: It turns out Loki (who actually makes a chess metaphor at one point) manipulated pretty much everything in the story up until the climax to insure his victory . Big Mac managing to outsmart him just prior to the Final Battle actually contributes to his Villainous Breakdown.
 * Composite Character: Fin Fang Foom is also the World Serpent here.
 * Possibly a Shout-Out to a story when Thor was "immortal" but very weak and confronted Fin Fang Foom only to find out it was Jormagandr in disguise.
 * Corrupt Corporate Executive: Obsidian Shade was apparently this even before he became the Iron Monger.
 * Curb Stomp Battle: Thor against The Wrecker.
 * Both Avengers vs Dark Avengers fights -- the first was this for the bad guys, the second was for the heroes.
 * Darkest Hour: Chapter 14 -- . Fortunately, the chapter ends with the below mentioned Rousing Speech, giving things a glimmer of hope, and by the next chapter things are already getting better.
 * Demoted to Extra / Out of Focus: The Mane Six, despite being the heroes in canon -- having saved the world themselves twice -- have almost nothing to do with the plot here. Pinkie and Rarity are secondary characters at best, only due to their relationships with two of the main characters; Applejack shows up even less, despite being the main character's sister; Rainbow Dash and Twilight Sparkle only show up in a handful of scenes; and poor Fluttershy only shows up in one scene and doesn't even have any lines!
 * Determinator: Much like his comic book counterpart, Caramel is this even before he becomes Captain Equestria (and is actually the main reason he was chosen for the project). This shines through the most during his fight with the Ghost Flyer, where he overcomes the Penance Stare through sheer willpower.
 * The Dragon: Trixie is Loki's only real servant for awhile, and even after the Dark Avengers show up, she's still his most powerful minion.
 * Dragon Ascendant:
 * Enemy to All Living Things: The Red Skull.
 * Epiphany Therapy: Near the end, Big Mac fully comes into his role when he realizes that
 * Evil Sounds Deep: Implied with the Ghost Flyer -- all of his dialogue is capitalized, and the first letter of each sentence is also in bold.
 * Fire-Forged Friends: Played with with the Avengers. Despite an initial fight brought on by a misunderstanding, they all get along pretty well -- but it's working as a team where they have trouble. It isn't until the fight with the Juggernaut that they learn to work together. After that, they're True Companions.
 * For the Evulz: Seems to be the Red Skull's primary motivation. While the other villains are after power and/or revenge, the only reason he gives for his actions is his belief in his natural superiority, but even that across as a pretty weak excuse.
 * There's also Gilda when she becomes the Juggernaut, but she was being manipulated (and possibly indirectly controlled) by Trixie and Loki, so she may not really count.
 * Fun Size:
 * God of Evil: Loki, of course.
 * Green Thumb: Caramel gains this ability in addition to super strength when he becomes Captain Equestria, due to his natural Earth pony abilities being amplified.
 * Ham-to-Ham Combat: Up to Eleven
 * Hannibal Lecture: Each of the Dark Avengers gives one to their good counterparts during their first confrontation. They try again during the rematch, but none of the Avengers take it this time.
 * Heroic BSOD: Each of the Avengers has one following the events of Chapter 14. It takes a talk from  to get Big Mac out of his, and he goes on to pull his friends out of theirs.
 * Hoist by His Own Petard:
 * Loki himself is defeated this way
 * I Just Want to Be Normal: Big Mac, for most of the story, until he finally embraces his powers.
 * I Surrender, Suckers: Loki pulls this during the Final Battle.
 * Kick the Dog: As if them threatening to  in order to get Thor to surrender didn't already qualify, the fact that Loki and Trixie threaten to do it slowly certainly does, if not verging on Moral Event Horizon.
 * Lampshade Hanging: Several characters point out how much this situation is like something out of a comic book.
 * Large Ham: Thor, Loki, Trixie and Luna all in one fanfic? The author included a warning tag, but with that character gallery, it shouldn't have been necessary.
 * Manipulative Bastard: Loki. And arguably Trixie, but she was just doing what Loki told her, rather than manipulating people herself.
 * Mass Super-Empowering Event: The destruction of Asgard ages ago is apparently what gave ponies the magic they have in canon and created Luna and Celestia. There's a second one early on when Celestia is attacked and forced to release her magic, giving random superpowers to those nearby.
 * Mind Rape: The Ghost Flyer's Penance Stare.
 * More Than Mind Control: Something else the Wrecker and the Juggernaut have in common -- they're both granted their powers by Loki (via Trixie) and do what they want with them, but are guided by a subliminal hatred of Thor (and the Avengers as a whole, in the Juggernaut's case).
 * Ms. Exposition: Pinkie is the one who explains the origins of Thor's powers and rivalry with Loki to Big Mac. As it turns out, she knows all this because she's.
 * Mythology Gag: During the epilogue, Twilight  is shown sealing away the demon Tirek, the antagonist from the G1 movie "Rescue at Midnight Castle".
 * Big Mac's first words to Loki as Thor in the Final Battle are a reference to a famous Big Damn Heroes moment the comic Thor and Avengers had against Ultron (which has become an on-and-off Catch Phrase for comic!Thor).

"AND YOU! ARE UNDER! ARREST!"
 * Near Villain Victory:
 * Nice Hat: Subverted. Big Mac refuses to wear Thor's helmet, because he thinks it looks ridiculous.
 * No Fourth Wall: Pinkie naturally.  It's a nice little tribute.
 * Odd Friendship: Big Mac and Pinkie strike one up, based on Pinkie being Ms. Exposition. It gets to the point that Applejack assumes they're dating (to their amusement).
 * Opponent Switch: How the Avengers beat the Dark Avengers in their rematch during the Final Battle.
 * Playing with Fire: Firebird and the Ghost Flyer.
 * Powered Armor: The Iron Pony and Iron Monger suits (though the latter is closer to a Mini-Mecha).
 * Power Crystal: Literally used to save Blueblood's life, in keeping with him being the Iron Pony.
 * The Power of Friendship: It turns out this is an actual magic in Equestria.
 * The Psycho Rangers: The Dark Avengers were specifically chosen as Evil Counterparts to the Avengers, each having similar powers to their opponents.
 * Public Domain Artifact: Mjolnir, of course. Odin's spear Gungnir shows up later in the story
 * Punctuated for Emphasis: How Caramel/Captain Equestria tops his Shut UP, Hannibal to Ghost Flyer:

"Applejack: Holy Celestia! Thor: Not quite."
 * Quirky Miniboss Squad: The Dark Avengers.
 * "The Reason You Suck" Speech: Fin Fang Foom gives one to Big Mac, telling him that he's just a cheap imitation of the real Thor, and not worthy of his power.
 * The Dark Avengers each incorporate these into their Hannibal Lectures during their first fight with the Avengers. They try again during the rematch, but the Avengers don't fall for it again.
 * Redemption Quest: Blueblood's story is essentially one of these. Similiar to Iron Man in the films.
 * Revenge: The primary motivator for many of the villains -- Trixie seems to want revenge on the world in general for not giving her the praise she thinks she deserves, the Ghost Flyer and Iron Monger want revenge against Spitfire and Blueblood (respectively) for perceived slights, and even the Wrecker's brief career is based on revenge against Rainbow Dash for upstaging him.
 * Rousing Speech: Big Mac gets one from a ponified, of all people, during the Darkest Hour. He then proceeds to give one to each of his teammates, pulling the team back together.
 * Secret Test of Character:
 * Sequel Hook:
 * Shared Universe: In the commentary for the epilogue, the author not only announces his attention to (eventually) write a sequel, but also welcomes anyone else to make additions to what he calls "Marevel Equestria" (so long as they don't use the Mane Six or Thor's team without his permission). To date, no one has.
 * Ship Tease: When the Princesses first meet Thor, Luna appears to develop a crush on him, though it never comes up again. Likewise, Celestia flirts with him, though that seems to be more to troll Luna than anything else.
 * Shout-Out: When Pinkie is first explaining Thor's backstory to Big Mac, she starts by giving him the basic information with what appears to be a psychic headbutt.
 * During the epilogue, when Twilight is sealing away Tirek, she does so with the "Chains of Mag'ne".
 * Gilda/The Juggernaut, during her fight with the Avengers, at one point shouts, "I'm the Juggernaut, bitch!"
 * Smith Will Suffice: This exchange when Big Mac reveals himself as Thor to Applejack:


 * Smug Snake: Loki and Trixie (the latter even moreso).
 * Split Personality Takeover: Big Mac spends most of the story worried that Thor will take over his mind.
 * Storming the Castle: The Final Battle occurs when the Avengers infiltrate Canterlot castle, which Loki's forces have occupied.
 * Time Skip: In the epilogue.
 * Took a Level In Badass: Caramel when he becomes Captain Equestria!
 * Big Mac, already badass as it is. Takes several levels by becoming Thor.
 * True Companions: The Avengers, following the fight with the Juggernaut.
 * Unwitting Pawn: The Wrecker and the Juggernaut, who were granted their powers by Loki simply as a way to lure Thor out of hiding (the former) and to test the newly-formed Avengers (the latter).
 * Villainous Breakdown: Loki loses it in the Final Battle thanks to the triple whammy of
 * The Dark Avengers have minor ones of their own -- the Ghost Flyer's is of the "This Cannot Be!"-inspired panic variety when Captain Equestria breaks through his Penance Stare, while the Iron Monger and the Red Skull go into blind rages following Firebird and Iron Pony's respective Shut UP, Hannibal and World of Cardboard Speech.
 * Visionary Villain: At times, Loki seems to want power merely for the sake of power, but really, he has a vision of a world ruled by magic (preferably with him as ruler), and seems to think it would be for the best.
 * Walking Wasteland: The Red Skull drains the energy from living things, so plants have a tendency to whither around him.
 * Wham! Episode: Chapter 13, in which the Dark Avengers first appear and defeat the Avengers, followed by chapter 14, wherein Loki reveals his Gambit Roulette.
 * Where Are They Now? Epilogue: Closes up the story, incorporating the later adventures of not only the central characters of this story but also
 * World of Cardboard Speech: Each of the Avengers (except for Firebird) give one to their opponents during the Final Battle.
