The Adventures of The Mysterious Mare Do-Well

Rainbow Dash was doing a night patrol of Ponyville flying above the city and sometimes spying down on the clouds. She had recently told Twilight Sparkle she wanted to become Mare-Do-Well again and she told Rarity to make her a Mare-Do-Well costume and pretty soon Fluttershy, Applejack and Pinkie Pie found out. They all agreed to keep her identity a secret from everypony in Ponyville. Rainbow Dash couldn't have been more proud of her friends and herself. Suddenly a scream was heard and Dash raced towards where the sound was made. It was from an alleyway and what was inside extremely shocked her. A pony was on the ground with swollen bumps all over her body and was dead on the ground.

Oh my, Celestia. Rainbow thought to herself.

On the ground next to the body was a note and she read from it.

This is the first of many that has been infected with the plague. The next five days the plague will strike again.

Signed, The Plague Doctor.

Our hero scratched her head in confusement and two questions piled up in her head: What was this plague and who was this Plague Doctor?

The next day news about the attack went everywhere in Ponyville. The Newspapers read:

Bystander killed by Plague.

Who is the Plague Doctor?

Everypony was in a panic, especially about the Plague Doctor's threat. Dash needed to figure out who this Plague Doctor was and what kind of plague did he mention.

"Who could be so heartless?" Twilight asked herself pacing around the library.

"I don't know. Who is this Plague Doctor anyway? And what kind of plague did he mention?" Dash asked herself.

Twilight then got an idea.

"Maybe if I knew what plague this Plague Doctor mentioned I can make a cure for it." She said.

"Good thinking. Let's see the victim had swollen bumps all over it's body and that's it." The blue pegasus explained.

Twilight then got out a book called Perplexing Pony Plagues and looked it up. What she saw shocked her.

"What? What is it?" Dash asked worried.

"The Black Death. That's the disease the victim had." Twilight said shocked.

Dash however was confused. She hadn't heard of any disease known as the Black Death.

"What is this Black Death?" She asked.

"The Black Death was a very deadly disease before Princess Luna became Nightmare Moon. It started out with fleas from rats infecting the ponies and getting extremely sick and dying. They all had swollen lumps on their bodies. Celestia and Luna tried many spells to cure them but none of them seemed to work. They eventually called on the Plague Doctors. They were tasked with ridding the Black Death once and for all. For twenty years the Black Death infected and killed ponies everywhere in Equestria until one Plague Doctor found out what it was. It was called the bubonic plague and created a cure and made everypony better." Twilight explained the history of the Black Death,

"But not it's back and the cure is long gone."

Dash was stumped and at the same time shocked. A Plague Doctor which was commisioned to cure the plague is now making it spread again.

Plague Doctor, whoever you are. I'm gonna take you down and prevent the plague from being reborn. She thought to herself.

In the four days that passed Dash a.k.a. Mare-Do-Well tried to stop victims from being killed but alas showed up too late. Everywhere she went there was an infected body and next to it was a note left by the Plague Doctor which foretold who was going to get killed. She then started training to make herself even faster to catch up but it still didn't work and the last note that was left by the fourth victim read: Four have gone and died. The final one is your Mayor and the Plague will be reborn.

Ponyville called a town meeting by the Town Hall to discuss what to do about the Plague Doctor. Everypony in Ponyville was there. The Mayor came up to a podium and spoke to the public,

"Citizens of Ponyville. In the past four days a dreadful disease has infected four unfortunate victims. The only leads are mysterious notes left by somepony named Plague Doctor. Whoever this pony may be he will not get away with these actions. In due time this Mare-Do-Well will be brought to justice and the safety will be restored!" She shouted.

Everypony in Ponyville cheered, Rainbow Dash was in the back of the crowd but flew up to see everything. Suddenly microphone feedback started and then the sound systems exploded and a maniacal laughter was heard and an evil voice was heard as well,

"You actually think you can stop the Plague? Well your all wrong. The Plague will live again!!!!"

Suddenly smoke was made around the crowd and Mayor Mare. A sillhouete then sneaked up to the Mayor and jabbed needles into her neck and shoved her down to the ground and disappeared in the darkness.  It was then seen that the Mayor was coughing extremely, coughing out blood and swollen lumps started to popping up and she was having a hard time breathing.

"She's been infected!!!!" Dash shouted.

"AH HA HA HA HA HA HA HA HA HA!!!!!!" The evil voice went and everypony looked up to see the Plague Doctor,

"Now you have 24 hours to make the Mayor better...... Or she will die like the rest! MWA HA HA HA HA HA HA HA HA!!!!!!!!!"

He then took off into the shadows and Dash went around an alleyway, got out her Mare-Do-Well costume from her saddle bag, put it on and chased after the insane doctor.

The Plague Doctor ran through the darkest alleys of Ponyville laughing to himself.

Those foalish ponies are now ocupied with the Mayor. Now I can put my plan into action. He thought to himself.

"HALT, CRIMINAL!!!" A voice went and the Plague Doctor stopped in his tracks.

He looked up to see the Mysterious Mare-Do-Well above him and fly down towards him.

"Ah. The Mysterious Mare-Do-Well. We finally meet." Plague Doctor said.

Behind the Mare-Do-Well costume Dash had a stern look and said in a deep voice,

"You won't get away with this Plague Doctor. When I'm done with you you're gonna need your medical skills to help yourself get better."

"Ha. Your threats don't frighten me. And I will get away with this....... However you are the only obstacle in my path." The villainous doctor said getting out a cane, gripping the top and pulling it out revealing a blade,

"Now it's time for your check up. Let's see if you can live long enough."

He then charged right at Mare-Do-Well and swung the blade but was blocked by Mare-Do-Well's hooves. He retaliated by bucking her into the wall and swinging the blade again but cutting a pipe causing gas to spill out. Plague Doctor then swung his blade all around trying to hit the superhero but she dodged every swing from the cane-sword. Mare-Do-Well saw an opening and shoved Plague Doctor into the wall and used her back hoof to kick him in the face. The insane villain then tried to bring his blade down to cut off our heroes' head but he missed and got it stuck in the ground. Mare-Do-Well then turned around and bucked him in the body and sent him into a wall and then flew into him keeping him from going anywhere.

"Looks like your next stop is the hospital." Mare-Do-Well joked.

"Hm hm hm hm hm. Not quie, you foal." Plague Doctor went.

In a matter of seconds syringes were jabbed into the masked pony's neck and then she was punched in the face and onto the ground. Dash felt extremely woozy and before she passed out she started into Plague Doctor's souless eyes and he said,

"Time to board the train to Sleepytown."

All Dash could see was black but then she smelled a sweet flower and opened her eyes to peer into the eyes of Plague Doctor.

"Good to see my patient is up. We wouldn't want you to miss your apointment." He said.

Mare-Do-Well tried to move but couldn't, she was strapped down to a gurney and she saw Plague Doctor's lair. It was a mix of a mad scientist's laboratory and a room in a hospital.

"I believe I can squeeze you in. I'd like to recomend one hundreed cc's of listen to my plan." The evil doctor said and walked over to the middle of the lair.

"All my life I've wanted to become a doctor, and I did. However nobody told me the patients would be so hard to contain. One paticular patient broke the straw on the cammel's back." Plague Doctor said in a venom filled tone,

"She was so fast I couldn't keep up with her, she fell asleep everytime I tried to entertain her and she kept calling me a lame bookworm for trying to read her a story. She kept saying she was the Fastest Pegasus in all of Equestria!!!! And that no good patient's name was...... RAINBOW DASH!!!!!!!"  He shouted.

Dash was very surprised, this psycho blamed her. And the way he described himself the lines then connected and he said,

"Dr. Black?"

"That's right!!" Plague Doctor shouted taking off his mask and revealing his black face, crazed eyes and messy hair,

"Doctor Black Checkup, at your service. But how did you know who I really was?"

"Uhhhhh...... Lucky guess?" Mare-Do-Well asked with the deep voice not wanting to reveal her identity.

"...... Lucky you may be....... But you won't be lucky in putting a stop to my plan." The villain said putting his mask back on and went over to a crate and continued,

"In this crate....... Is over one million fleas all infected with the Black Death..... Or do you prefer the bubonic plague? Either way I'm going to drop them all over Ponyville and watch them bite the citizens as each and everyone of them is bit and infected...... And I have the only cure."

He then revealed the cure on a table next to him.

"If they want their city to be cured they'll have to get the cure from me..... For a price....... And if they don't...... They die." Plague Doctor said with an evil tone.

"Your crazy!!!!" Mare-Do-Well shouted with a disguisted tone.

"NO!!! That would imply mental illness or schitzophrenia..... I suffer from neither. Now if you'll excuse me I have a bubonic plague to make reborn." Plague Doctor said lifting the box full of fleas with his magic and teleporting out of his lair.

"I gotta stop him.... But I gotta get myself free." Dash said wriggling to get herself free.

She then eyed a button on the side of the gourney that must be the button to release her. She wiggled one of her wings towards the button, Plague Doctor didn't bother strapping the wings, and pressed it and she was free of the gourney.

"Now to stop that crazy doctor." She said and then took flight to stop Plague Doctor.

Plague Doctor was on the dam and slightly chuckled to himself as he lifted the box full of infected fleas and dumped the fleas into the water that the dam was blocking.

"Soon......  Ponyville will feel my revenge and I'll be rich beyond compare." He said to himself.

"The only thing rich will be your face when your behind bars." A voice said.

Plague Doctor looked up to see Mare-Do-Well on a cloud right above him and she flew down to the dam to confront him.

"Ah Miss Mare-Do-Well, your quite the stubborn patient..... But I'm giving you one last checkup." Plague Doctor said and got out his cane-sword and syringe glove,

"The check-up will begin..... AFTER YOU DIE!!!!!"

He then charged towards his adversary and swung his sword but Mare-Do-Well ducked and then tripped Plague Doctor on the ground and he slid on the surface of the dam causing him to lose his grip on his cane sword which fell off the dam. He then got back up and charged again with his syringe glove to infect Mare-Do-Well but his hoof was grabbed before the needles could jab into the heroes' skin and then she twisted the hoof making Plague Doctor yell in pain and the glove fell off and Mare-Do-Well threw a punc which socked the bad doctor in the face. He was sent flying for a bit but got back up on his hooves and charged again sending furry and punches and kicks which were blocked by Mare-Do-Well and she countered with a beatdown of her own and ended with an buck to the face which sent him flying into a tree and a branch landing on his head knocking him out.

"Looks like the only one that needs a checkup is you, Plague Doctor." Mare-Do-Well joked.

Later that day the Mayor was cured from the plague using the cure that Plague Doctor kept in his lair and he was sent to Alkatrot Prison to pay his debt to society. The newspapers read:

The Mysterious Mare-Do-Well saves Ponyville from bubonic plague

Plague Doctor sent to prison for 10 to 12 year 'Check-Up'

Everypony was glad that Mare-Do-Well had returned to keep Ponyville safe, and the mare behind the mask, Rainbow Dash.... Couldn't be more happy.

Alkatrot Prison

Plague Doctor paced in his cell and mumbled to himself,

"I'll be free one of these days Mare-Do-Well........ And when I do get out of here...... I'll find you......... And you take a thousand cc's of 'My Revenge.'"

Suddenly something smashed through the window in his cell..... He looked at it and saw it was a package. He opened it up revealing his Plague Doctor costume and metal suit that had some mysterious gas in it and a note that read,

I've been watching you Doctor, I've seen the things you've done...... With these you'll be able to exact the revenge you deserve on Ponyville and Mare-Do-Well. The Plague Doctor is going to make a revenge call.

Signed,

The Revenger
