When District Attorney Luna is mysteriously poisoned, Mare-Do-Well soon traces it back to Manehattan's newest supervillain, Thorn Briar, who has a past grudge with the DA...

My third Mare-Do-Well re-write of a classic Batman: The Animated Series episode, based off of "Pretty Poison." Here are the other two:

Hearth's Warming with Discord

Nothing to Fear...

Inspired by devastating personal losses, Apple Bloom dons a mantle from her youth to counter Equestria's rising crime after a dramatic change in government sends Canterlot into disarray. As more heroes follow her lead and arise in other cities, she must face her own past and dark new evils on the path back to harmony.

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!

Set shortly after The Mysterious Mare Do Well.

Perhaps Rainbow Dash had read a few too many comic books? Seen one too many hero movies. Either way, this was not going to end well for anypony.

Rainbow Dash has decided since each of her friends (aside from Rarity) have gotten a chance, she wants to give being The Mysterious Mare Do Well a try. The only problem? Ponyville is too peaceful. It seems all the craziness that had happened the past week has passed, and there really isn't any need for a costumed crime fighter now.

Twilight, seeing Rainbow Dash's annoyance at not being able to be a hero, takes it upon herself to help her friend experience a super hero adventure. By creating the powerful, the terrifying, the surprisingly sarcastic, Professor Nightshade.

Yeah, this is totally going to end well.

My entry into the TwiDash group's first Fanfiction Contest.

Yes, this is for the TwiDash group, so there will obviously be TwiDash inside.

***Story is currently being edited, please excuse the mess!***

A masked and mysterious pony has come to Ponyville! He's looking for the bravest, strongest pony in town- and where better to start, than with Rainbow Dash?

After a brutal lie that destroys Cheerilee’s life at the core, she takes on another, crime fighting persona.

The original author of this story has not updated it, or even posted a story in over five years. I couldn’t stand being left with such a crucial cliffhanger, so I thought I would finish it myself. The first part of the story is here:

I hope I do it justice.

Cold Star is a Crusader: a Bat-Pony sworn to defend the Sacred Night. Adopting the guise of the Mysterious Mare-Do-Well to hide her forbidden ancestry, she came to Manehattan with a single purpose - to bring justice to those who would do evil under the cover of darkness. The last thing she expected to discover was a group of cape-wearing young ponies also claiming to be Crusaders.

This story is a sequel to Edge of the Ponyverse

Six heroes brought together by fate, or something more? Mare Do-Well, Fili-Second, Flutterbat, Rainbow Dash, Nightmare Rarity, and Applejack must travel the multiverse in search of a villain who wishes to do the unthinkable. End Harmony itself.

But will this ragtag team of adventurers be able to come together? Or will they be torn apart by forces beyond their understanding and control?

I don't own anything!

(NOTE: Undergoing a massive rewrite due to massive dissatisfaction on the author's part. Augh.)

The last thing the Mysterious Mare-Do-Well remembered was a foalnapping that had quickly spiraled out of control. Then, to her astonishment, she’d found herself in a place that seemed straight out of an old mares’ tale—a ship that could navigate the stars, sailing a river far larger than any in all Equestria.

She learned that this river, the great Eridanus, was a bridge between worlds—and that some primeval force threatened the existence of not only Eridanus, but Equestria as well.

Meanwhile in Manehattan, whispers are traveling the streets—tales of ponies disappearing into thin air, and rumors of vicious creatures, neither equine nor beast, that can walk among ponykind without suspicion.

Now, the Mare-Do-Well must wield a magic as old as Eridanus itself to destroy this ancient evil. But is her newfound power worth turning her back on a promise she made long ago?
