Pony Fortress 2: Meet the Medic

Camera follows Rainbow as she crash-lands on a small plateau, tries to force herself up, and fails. She's in pretty bad shape as well--bruises all over, hooves bleeding, left wing looks broken, bandage over her chest, the works. Ominous drumbeats and a bomb whistle in the BGM as she looks up to see three rockets converging on her. An overhead reaction shot details her terrified face, black left eye, and missing tooth.
Rainbow (panic): Oh, HOLY BU--!

Cut to another, slightly steeper hill (BGM stops). We see that explosion in the distance, and Rainbow hurtles toward us screaming bloody murder. She slams into and cracks the screen (which is a window), giving us a lovely image of her squished and now bleeding face. Sound of glass tinkling to the floor. A little bluebird pops in from the right and looks curiously at her.
Rainbow (weak): Medic...!

<cue title card. At the end of it, we hear Big Macintosh laughing.>
Fluttermedic (voice): ...Wait, wait, it gets better!
Cut to the inside of an operating room. We're looking at some kind of support as Rainbow falls from the window. Pan down as Fluttershy talks to reveal a much larger version of the medigun, which that bluebird is perched on. Macintosh (on the operating table with an open chest wound) and Fluttershy (holding something red) eventually become visible but somewhat blurry as the camera pans right. Various birds and little critters sit on any available perch, watching.
Fluttershy (continuing): When the patient woke up, all her feathers were missing, and the doctor was never heard from again! Hahahaha!

They laugh. Clearer shot of Fluttershy and Mac (side view); Fluttershy's classy light gray sweatervest has faint red marks on the front. She wears two pairs of plastic gloves over her front hooves, one of which lightly rubs her forehead. Oh, and she has skinny oval glasses for some reason. (The end of her shirtsleeve is bright red, and her other hoof is holding Mac's heart) Oh, by the way, there's a heart monitor behind Mac.
Fluttershy: Anyway, that's how I got banned from Baltimare.
Mac's eyes pop open in shock. Before he can ask what she means by that, a strangely rabbit-like white dove pops out of his wound, further startling the both of them.
Fluttershy: Wha--Angelus, get away from him! *shoos the bird off* You've given me enough trouble already. (Mac gives her a weird look. She shrugs apologetically) Birds. Hee-hee.

Brief close-up on a metal tray behind Mac's head. Fluttershy's left hoof grabs a three-pronged metal thing that looks like a pressure gauge with the word "Über" stamped below it.
Fluttershy: Now, most hearts couldn't withstand this voltage. (MS; she sticks the device into Mac's heart. Camera follows her as she brings the medigun a little closer and his enhanced heart into the beam) But don't worry, I'm sure yours--
Ka-POP! Macintosh's heart explodes (cue "Meep!"), and we get a brief image of one piece clocking Angelus on a perch that also hosts a canary and a squirrel. Focus back on Fluttershy, staring at the charger in total disbelief. (The heart monitor has flatlined.)
Mac (looking around): What was that noise?
Fluttershy: ...trial and error, my friend. *flicks the remains of his heart off the charger*

Close up on a mini-fridge. Slightly ominous music plays as Fluttershy opens the door and grabs a heart from a Petri dish labeled "Hippogriff." (You may mentally insert what amuses you on the other labels.) This action also reveals BLU Spyrity's disembodied head hooked up to the equivalent of a car battery.
Fluttershy: Ooo, this one!
Head: Kill me.
Fluttershy: Later. *door closes*

MS of Fluttershy. She discreetly wipes down the prongs on the charger. (Cue slight Ominous Latin Chanting)
Fluttershy: Where was I? Oh, right. Here we go. (sticks the charger into the hippogriff heart and the heart into the healing beam. Close-up of it throbbing in her hooves) Come on, come on...Ha-ha-ha. Hahahahaha...! (progresses into a full-blown Evil Laugh, and the camera abruptly zooms out into an overhead shot so we get the full spectacle.)
Mac (awkwardly): Ha-ha...ha...ha...?
Close-up of Fluttershy. She's no longer laughing; her head's pulled away from the heart as though she expects this one to explode, too. Its ominous red glow illuminates her face from below... (BGM crescendos, becomes slightly frantic)
Cut to the perch. The squirrel and canary nervously shuffle away from a now-bloodstained Angelus.
Back to Fluttershy's head...everything just stops for a second. She looks down in surprise (MS); the hippogriff heart is encased in a shiny red armor and thumps patiently.
Fluttershy: Huh, that looks good. *carefully places the new heart inside Mac's chest* All right, this goes in here...
Shot of Mac's face. He looks confused and slightly alarmed.
Mac: Should Ah be awake for this?

Shot of Fluttershy at a similar angle.
Fluttershy: *awkward giggle* Not really, no, but since you are...could you maybe hold your ribcage open just a little? *begins pushing the heart in* I'm having--a slight--problem--oh, dear--
Snap! Cut to Mac crying out, then a quick MS of him holding one of his ribs. Fluttershy panics slightly.
Fluttershy: Oh my goodness. Don't cry, don't cry, OK? It'll grow back, I promise you the rib'll grow back. *She rubs Mac's cheek in a motherly way, then puts the rib and her first pair of gloves in a biohazard container.*

Small close-up; Fluttershy's getting ready to use the medigun.
Fluttershy (whispering to the bluebird): No it won't. *bluebird flies away*

More slight Ominous Chanting in the BGM as Fluttershy fires the medigun, completely closing Mac's chest wound (camera follows it to Mac's surprised face as the beam works) and replacing the Kevlar. Mac places a hoof on his chest, which has a glowing red circle like Tony Stark's palladium core, and takes a deep breath.
Mac: So what now?
Fluttershy: Now? *helps him up and chuckles. Close in on her face, lit sparsely and with an adorable psychotic grin* Let's go practice medicine.
Drumbeat, cut to black. Montage of Fluttershy suiting up--heavy red rubber gloves on (snap), labcoat swishing over her back hooves dramatically, charge pack on her back (with a faint "Oof"), and medigun ready.

Cut to a pair of metal doors emblazoned with a red cross. They slide open slowly to reveal Fluttershy striding out in a burst of light and dove-like birds (cue "Oooooooooh" in the BGM). Close-up; drum stops, and she swallows once. Then Mac charges out, and the ominous BGM kicks in again. Camera goes over Fluttershy's shoulder; chaos reigns. We can sort of see Zecora rolling downhill; a close-up confirms her identity.
Zecora: MEDIC! *explosion knocks her out of the chair*
We get a nice view of Zecora faceplanting. Close up on Fluttershy's face: she nods resolutely, flicks a small switch, and pushes the handle on her medigun forward. (cue electric guitar in BGM) A beam of red magic comes from the tip and touches Zecora's head. Camera follows the zebra as she stands up, casually brushes off her bandages, grabs her grenade launcher, and runs back into the fray.

Now it's Rainbow Dash's turn. The healing beam makes contact with her back, and we get a close-up of her face as she stands. She shakes her (clearing the redness), and grins as the lost tooth grows back (cue twinkle).
Rainbow (jumping up): Yeah! *grabs her bat and zooms off past serious Mac* Woo-hoo-hoo!
Cut to a BLU Soldier Ditzy waiting behind a rock. Rainbow flies by and clobbers her with an "OH YEAH!"

Mac's using a boulder for cover and takes a quick look at the other team. Jump cut: A herd of BLU ponies (mostly Ditzies) is visible, slowly approaching our heroes.
Macintosh: Fluttershy! (cut to him) You sure this'll work?

Close up of Fluttershy. She looks a tad bit demented.
Fluttershy: *giggle* I have no idea!
Music grows ominous again as she pushes a small switch on the bottom of her medigun. The needle on a dial goes all the way into the red zone, and a button below it reading "ÜberCharge ready" lights up in orange. Brief shot of the charge pack emitting healing gas, and a back view of Mac emerging from cover. He yells a battle cry as solid red armor forms around him (brief shot of the heart thumping rapidly), causing his eyes to glow yellow. Close up of a non-armored Fluttershy. She smiles triumphantly and moves forward while supplying energy to Mac.

Shot of them moving forward. A rocket hits Mac dead-on, creating a huge cloud of smoke. His glowing yellow eyes appear in said cloud, followed by the rest of him a short time later.
Mac: AHAHAHAHAHA!

Cut to RED Apple-engie and RED Twilight Sniper using a different boulder for cover. As Mac/Fluttershy stomp past, they lower their weapons and adopt near-identical "Holy shit what IS that??" faces.
(front view of Ubered Mac firing away) Mac: AH'M BULLETPROOF!

BLU team rapidly forms a mountain of rocket-firing corpses. Mac and Fluttershy advance regardless. Close up of one (Ditzy) corpse with four stars on her helmet. Mac's front hoof grinds it into the pile (MS) which he and Fluttershy now stand triumphantly on top of (cue beams of light). Doves fly away above the two of them and Mac keeps on firing.
<outro>

A waiting room. Applejack plays guitar, and in the front we can see RED Spyrity looking at a picture of somepony. RED Pinkie Pyro has a comic book in her hooves, and she casually flicks a lighter on and off. Camera pans left to show the other mercs waiting in cheap plastic chairs and a "Please Take a Number" display on the wall. Ditzy stands patiently, Zecora casually sips her tea, and we can hear Fluttershy talking.
Fluttershy (voice): All right, this goes back in here, and...done!
Rainbow (voice): Awesome! Thanks, 'Shy.
Ding! The number on the display clicks from one to two, and the door to Fluttershy's operating room opens. Twilight (closest to the door) looks at the door, interested. POV shot of Rainbow emerging with a glowing chest.
Rainbow: Whoa-ho-ho, man! You would not believe...! (close up with view of Fluttershy) How much this hurts. (Her chest pulses all of a sudden, and she looks at it in surprise.)
Bird (muffled): Crrooo. (cut to black)
Fluttershy: Angelus?!
