"Princess Celestia, I still don't understand. Why did you wake me in the middle of the night?" the lavender alicorn was tired, as she raised the stars each and every night.
'Twilight." Princess Celestia said. "I have a student for you."
"Couldn't we wait until morning?" Twilight was growing impatient. Why did this happen in the middle of the night?
"She's far too important for that. Celestia said. She turned and faced a light pink alicorn, with eyes that constantly changed color. She apparently had cat ears and a cat tail. She had a rainbow mane with lots of sparkles and the tips of her wings were illuminated with a pattern of tie-dye that moved around like wind over water.
"Twilight, this is Princess Sparkle Midnight Sonic Rainboom Perfect Kawaii Desu Neko Star The Third."
"My friends call me Mary-Sue." she said.
Twilight Sparkle stared at the pony before her. She was overpowered, for sure, and Twilight wanted to know why.
"How did you find her? Where is she from? Did she have any brothers or sisters?" Twilight started listing questions left and right.
"I am the sister of Rainbow Dash!" Mary Sue said. "Then, our parents realized how much more awesome and pretty and perfect I was then her, and they made me into an alicorn! Not only that, but a princess! Because I'm so perfect!"
"And I thought Rainbow Dash and Applejack were full of themselves..." Twilight mumbled to herself.
"Well," said Celestia, "She also happens to be prettier than both Luna, Cadence, and I, but most of all, you!" Twilight just stared at Mary-Sue, jaw dropped. "I do hope you teach her well in magic, however."
"Really!" Twilight was now happy as can be. Finally, something Mary-Sue wasn't up-topping her at!
"I was talking to Princess Sparkle Midnight Sonic Rainboom Perfect Kawaii Desu Neko Star The Third. Not you!"
"THEN WHAT AM I SUPPOSED TO TEACH HER, AS HER MENTOR?!?!" Twilight was furious and began to slowly turn pale as she elled more. "I MEAN, I AM HER MENTOR, AREN'T I?!"
Celestia sighed. "Calm down, Twilight, I know what you are going to teach her."
"THEN- I mean- then, what is it?" Twilight calmed down a bit.
"Celestia walked closer and whispered in Twilight's ear. "Friendship." she said. Then she walked away and announced, "Now, take her to meet your friends in ponyville. There will be no train ticket fee."
Twilight decided she had no choice to take this "Princess Sparkle Midnight- whatever" to ponyville.
