My Little Pony and... South Park?

"Ah! Who are you?" Butters screamed at Chrysalis.

"Me? I'm Queen Chrysalis, and with my changeling army I shall conquer all of Equestria, you foolish little mare!" She told them as she encased them all in green cocoons.

"Now, you're probably wondering why I'm here..."

"Oh God..." Kyle mumbled.

"We don't care!" Stan yelled at her.

"Well, about six months ago, I tried to conquer Equestria by posing as Princess Cadence. Needless to say, my attempts failed all thanks to this dead bitch's prize student, Twilight Sparkle... If it wasn't for her I could have become the ruler of this Luna forsaken place. But now that she's gone forever, I can finally seize control!" She told them. They rolled their eyes at her story, because they seriously didn't care.

Kenny wiggled and squirmed in his cocoon. He hoped that he could get out of the damned thing if he just tried a little harder... He felt something pop by his horn. It turns out he'd managed to loosen the goo around his head, meaning that he could use his horn to poke through some of the goo.

"Just... a little... more..." He thought as he felt the cocoon loosen around him. Kenny shook and he jiggled and after what seemed like forever the cocoon fell apart, freeing him. He looked at his friends, who were to focused on their own escape to notice his. Chrysalis was to busy gazing out of the castle window to care about her six prisoners, so Kenny wasn't worried about her noticing as he ripped open the cocoons of his friends.

Just before Chrysalis could spot them, the six boys ran out of the throne room.

"GAH! Thanks for freeing us Kenny! That maniac could have KILLED us!" Tweek said to Kenny as they galloped down the corridor. Suddenly they were stopped by a dark blue pony with a long flowing mane. She told them to follow her into Celestia's bedroom, for it was the safest room for them to talk in.

"Boys, I know how you can defeat this maniac!" She told them.

"How the hell are we supposed to defeat that crazy bitch?" Cartman asked.

"Well, it won't be easy. I will have to give Kenny a power which he may be familiar with." Luna explained to a confused Kenny. She then cast a spell on him which knocked him unconscious.

"Don't worry boys, your friend will be okay..." She said before disappearing into thin air.

Kenny woke up in a place he thought seemed familiar. He turned around to see Princess Luna calmly walking towards him.

"What's going on? Where are we?" Kenny asked her. Luna simply smiled at him before giving him a box. He opened it, and was engulfed by a ball of light.

"Where did she go, where did she go?!" Butters was panicking.

"Dude, Butters, I don't know. She knocked out Kenny and just disappeared!"

"But, what if she NEVER comes back, and we're killed by that crazy pony! GAH! What if we never get home?" Tweek couldn't stop panicking.

"How the hell is a faggy PONY gonna kill us, you guys?" Cartman said.

"She killed the Princess, fatass!" Kyle began to argue with Cartman.

"Ay! I'm not fat, I'm just big boned!"

Before the boys could start an argument, they saw Kenny's body rise into the air. He then transformed into a beautiful Princess, the most beautiful they'd ever seen. Luna then re-appeared, and the boys knew what Kenny had to do.

Kenny had to battle Chrysalis in the ultimate final battle.
