Sombritis

The infected ponies, numbering 10,000 Equestrians, charged at the two survivors. Doctor Whooves and Derpy fired up their weapons and blasted the cure into the first pony they came across: Mayor Mare!

"Goodness". said the doctor, being thoroughly shocked. "I thought she would be one of the first to be infected!"

"We have to save everyone single one of these ponies!", shouted Derpy, panicked. Suddenly, 5 infected ponies leapt on top of her and began to tear into her!

"NOOO!!! GET AWAY FROM MY ASSISTANT, YOU FOUL BEASTS!!!" screamed Doctor Whooves angrily. In a firing frenzy, he began to destroy every infected pony in his path, without even aiming. Several ponies were cured at once, but most were disentegrated, to the doctor's horror. "Bloody hell!", the doctor cried to himself. "I must calm down! I do hope that Derpy is OK".

However, the doctor was still by himself as he continued to battle the infected one-on-one. He wished that Derpy was at his side so they could have an easier shot at curing everypony. It was getting rather difficult as he continued by himself. "Oh, Derpy!!!", cried the doctor to himself, "Where have you gone?! You are my most trusted partner! I would never do anything without you!".

Suddenly, Derpy reappeared next to him, much to his delight. However, something looked different about her. For a split second, the doctor almost thought she was infected, but it turned out she had become immune to the virus! In fact, she looked like she could cure everypony all at once! It was like she had become an angel!

"Derpy!", said Doctor Whooves. "Thank heavens you're here! I thought you had become one of them!"

"Nope, I'm perfectly fine", said Derpy confidently. "Whaddya say we take care of the rest of these baddies?"

"Absolutley!", said the doctor. But before they could do anything, a voice cried out:

"HEY!!! THAT'S MY LINE!!!

"Rainbow Dash", cried Derpy in fear and horror.
