Get ready for a fic I'm not sure any of you have seen before! I saw the death battle featuring Deadpool and Deathstroke, and I figured why not give one of the Mane Six Deadpool's powers? So, here we are now. I hope you all like it.

Prologue: Terrible News!

It was the rehearsal of a big event in the kingdom of Canterlot. And not just any event like the Grand Galloping Gala. This was a royal wedding. The marriage between Princess Mi Amore Cadenza/Cadence, and Shining Armor the captain of the royal guard. Yessir this is sure to be a momentous occasion, right? ...Well, for those of you who said yes, I'm afraid you're wrong.

You see, when the bride and groom were about to give their vows during the rehearsal, Shining Armor's younger sister Twilight Sparkle burst into the room shouting things about how Cadence was evil, and was controlling her brother through the use of mind control spells. When she said this, Cadence ran out of the room crying, and Shining Armor snapped at her saying how the constant use of his shield spell was giving him migraines so Cadence was using a spell that was meant to heal him. He was so mad in fact, that he practically kicked Twilight out of the wedding! But before anypony else could say anything against her, she dropped a bomb on them... Not literally mind you.

"Well fine! If you all don't want me in the wedding anymore, I won't show up at all!" Twilight said with angry tears in her eyes. "I'll just go curl up in my room and let my cancer kill me! Then none of you will have to put up with me anymore!"

Hearing this made everypony's expressions change from anger and disappointment, to shock and sadness. They finally got a good look at Twilight. She did look sicker than she should be, and they could tell that she was somewhat straining to breathe. Twilight realized what she'd said, and lowered her head in sadness and shame.

"...Wha...what?!" Shining asked in disbelief.

"It's the truth, Shiny..." Twilight said with tears leaking from her eyes. "I've been diagnosed with cancer."

Everypony in the room had different, yet similar reactions to what Twilight had just said. Rainbow Dash had stopped flying, and was just sitting there wide eyed and open mouthed, Applejack looked like she didn't wanna believe it, Fluttershy was starting to cry, Pinkie's ever poofy mane and tail had deflated and her colors had grayed slightly. Rarity was trying and failing to hold back her tears, Twilight's mother was openly sobbing while her husband tried to comfort her, Shining Armor looked like he wanted to cry but couldn't, Spike was letting his tears fall without restraint, even Princess Celestia could not stop her tears from falling.

"Why...? Why didn't you tell us? We're your friends, aren't we?!" Rainbow Dash asked feeling betrayed by this withheld information.

"I had found out only yesterday. I wasn't feeling so good during the preparations for the wedding, so I went to the Canterlot Hospital. When they told me about this, I was devastated. I didn't want any of you to go through the same..." Twilight explained.

She began to walk past the others with her head down.

"Twi? Where're ya goin'." Applejack asked.

"Just leave me alone! I don't want any of you to burden yourselves with a mare who's doomed to die!" Twilight cried as she ran out of the wedding hall to her old room in the palace, crying the whole way. That's when everypony saw Cadence staring in shock and sadness at Twilight's retreating form.

"Dear Faust above..." Cadence said as she herself began to cry. "...What have we done?!"

Well folks, that's all I got for the prologue, but I'll try to make the next chapter longer than this one. For now, I'd like it if you all can tell me if you think I should involve Celestia and Luna's mother and father in this story. If so, they might play a very important part.
