Sunset Shimmer, the protege of Princess Twilight, originally planned to wear her mentor's old Mare-Do-Well costume to a Nightmare Night party. A near-disaster that evening drove her to keep it, taking up the role of Equestria's newest hero.
Takes place after Season 4 in an alternate timeline where the Equestria Girls series and The Cutie Map, and as a result the map episodes of Season 5, never happened.
My first attempt at fan fiction. Any constructive feedback is appreciated!
Special thanks to my proofreader (Chapters 22 & 23), professorsawyer!
Chapters (25)
Well done. Looking forward to see where this goes. This would be an interesting "Summer Job" from high school or graduation, but I get the feeling this Sunset never ended up in Canterlot High. Still, looking forward to see where our favorite Batman-expy goes from here.
Good job dude! Can't wait to read more! Also can't wait to see what villains you got coming our way!
5502301 Yeah, this isn't the Sunset Shimmer from the Equestria Girls universe. After she and Celestia had a falling out, she was sent to Ponyville to learn about the magic of friendship from Princess Twilight. Basically, Twilight's proven to be a more effective teacher.
Glad you're liking the story so far!
5502321 Thanks, glad to hear you like it! Still brainstorming ideas, but I think I've got a villain planned out!
5503650 May I state one for later use? You know how Mare-Do-Well was inspired by Darkwing Duck? Why not give her a character named Negamare?
5503651 I'll think about it.
5503660 If you do you MIGHT wanna hit more on the lines of how Red X was in the Teen Titans cartoon.
This is pretty good, Looking forward to more.
Great story!! You just got yourself 5 smiles
super duper happy
Has a lot of potential, I look forward to seeing where it goes.
5503915 Thanks! There's a little something in the next chapter that I'm sure you'll love.
5503865 5503755 Really glad you're enjoying it so far!
Good work so far, though Sunset just needs to remember next time she does know teleportation that can probably help her escape being pinned or restrained.
Loved Rainbow's "costume"
Ooh, I like this. I'll keep reading!
I am vengeance. I am the night. I am... Mare-Do-Well!
5508681 Don't worry: Sunset's a more experienced fighter now, and she's learned to keep a level head even when a dozen thugs are ganging up on her.
5508826 Glad you like it! I'm also liking your MDW story, looking forward to more!

For some reason when I read your comments and look at your avatar I imagine Luna reciting them in the Royal Canterlot Voice
5509342
It definitely will be to her benefit. Wonder if she's gonna become a complete foal magnet(on par with Twilight in Twilight Time) thanks to her new career choice whenever she's in costume
This is awesome!!!a
5512950 Glad to hear you're enjoying it!
cool story. I can't wait for more.
5514839 Glad to hear you're enjoying it!
A very cute and enjoyable chapter, almost like a training montage.
So whose the new villain? This'll be cool to see when we get a better look at them I imagine. Part of the fun I had with my trilogy was coming up with the various villains' designs
5528947 I just imagined all of our villains hanging out in a pub, downing drinks.
"What happened to you?"
"Mare do Well."
"... You too?! That mare is everywhere."
"Tell me about it."
5528947 Glad you enjoyed it! I'm still ironing out the details for the villain, but I think I've got a name for her.
5529156 Then Rainbow Dash, Snow Storm, and Sunset Shimmer enter, and there's an awkward silence as the two groups of ponies stare at each other...
5529481
Neat! Lately I've been doing sketches of a pony version of the Big Hero 6 villain(oddly have not seen any so I decided to do some myself)
That'd happen in a Crisis-style crossover
5529481 Let's not forget Loop D'Loop and El Toro, MagnetBolt's MDW and villain. There'd be a bar fight in no time.
5529952 The Element of Loyalty, a rogue changeling, a mute earth pony, and an ex-student of Princess Celestia, in a bar fight against a couple of Equestria's nastiest villains...
Those villains are SO screwed.
5530106 What makes it even better is lately I've been amusing myself with thoughts of Snow dressing up as Sub-Zero. Loop would be Ermac, Dash could only be Johnny Cage, so would Sunset be Scorpion?
5530288 I don't play Mortal Kombat, so I wouldn't really know.
I'm Batman... Uh, I mean, Mare-Do-Well.
nicely done
, though i think you forgot to have Sunset mention Night Shade to Celestia , unless you are waiting until later to bring that up, other than that nice job 
5542042 Uh... I actually did that already...
5542092 Wait, *Looks back at story* oh
my bad I didn't notice it.
Nice update keep it up!
Night Shade, huh? Sounds like trouble, but nothing Sunset can't handle!
Also why is it that Daisy kinda reminds me of Poison Ivy?
5549483 Well, both of them really love plants. Difference is, Daisy's love of flowers is nowhere near at the same psychotic level as Poison Ivy's.
5543057 Glad you enjoyed it!
So, Celestia already figured out Sunset's secret. Big surprise there.
Finally got time to read the first chapter, and it is pretty good so far.
Something's going on...
I can tell.
5562676 Yep. Besides the Mane 6 and Spike, the Princesses and Stray Wind (from Chapter 2) know that Sunset is MDW.
5563925 Glad you're enjoying it so far!
And yeah, Sunset's about to have a run-in with her first villain. 
Hmm.... Why am i suddenly imagining theres going to be more to Sunset's friend Stray Wind then a simple Cosplay fanatic.
5565516
You and me both.
5565659 I wouldn't be terribly surprised if she was Night Shade, either that or crazy (for cosplay) enough to try and become sunset's sidekick
5565701 5565659 I'll just let you two ponder about that...
5565701
I'm hoping the latter happens.
5565728 I would hope so ^_^ because tossing theories back and forth while containing to read new chapters as they come out is fun, and reading others theories and ideas in turn tends to inspire you (and writers of other stories )
5565826 you mean becoming MDW's Side kick? That would be cool, but what would she call herself? what would her costume be?
Okay, now you're trying to tease us with the references.
Take that, Christian Bale.
5571366 Heh, they're also references to costumes the real Straywind has actually made/worn, right down to the corset making her Snow White costume difficult to wear.
Funny thing is, I was watching "The Dark Knight" while I was putting the finishing touches on this chapter, but the thing that was actually on my mind when I added that part was a riff on an Arkham Asylum LP where the player keeps randomly saying "I'm Batman." (NSFW: swearing)
Ohhhhhh, shit.
Mare-Do-Well AND Daring Do vs Night Shade?
.....This gone be goooooood! :rainbowkiss.
Nice update!
