Once upon a time, there was a wizard girl named Gwendolyn Malfoy. She was Scorpius's twin sister, and she looked exactly like her mother, (Hermione Granger) except that Gwen's hair was long, brown and wavy with purple streaks, pink highlights and blond on the tips, but it was cropped short with strands of blue, green, black, red, magenta and other colors in it.
Her eyes were colorless, but they looked gray in the winter, green in the spring, blue in the summer, and brown in the fall, and they looked hazel in the dark and magenta in the light.
She dressed awesomely, in very fashionable yet time period appropriate wizard clothes, from a very fashionable yet time period appropriate wizard clothing store, because her parents gave her as much money as she wanted. But Gwen wasn't spoiled. Perfect people never are.
Gwen hung out with Albus and Lily Potter, Hugo and Rose Weasley and was dating James Potter, even though every other boy she had ever met liked her. Gwen wanted to break up with James, because she was secretly dating Albus, Hugo, Louis Weasley, and Teddy Lupin, and didn't want to affect their friendship because of this.
Gwendolyn was in sixth year on the Gryffindor Quidditch team , but she was a rotational player, and played every single position by herself, because she was so perfect and amazingly talented. She was so smart that she skipped two years at Hogwarts, even though every die-hard Harry Potter fan would claim this was totally impossible. Gwen was just that perfect and amazing.
But really, she wasn't a wizard, a veela, or even a *shudder* Mary-Sue. Gwendolyn Malfoy was a Mary-Suebot, a new technology that implied perfection with a chip in the back of the neck. But all of that was soon going to change, hopefully.
Present Harry and Hermione had contacted their past-selves, (The Association for the Extermination of Mary-Sues, or AEMS for short) and they were on their way. But not fast enough.
One day, as Gwen skipped through the forest, the birds were singing because she was so beautiful, and perfect, and talented, and... whoa, lost my train of thought. Anyway, a bunch of birds were making noises, got it? Good. Moving on, she passed James, Albus, Hugo, Louis and Teddy, who were having a duel of who would get to ask for Gwen's hand in marriage, and Rose, Lily, Dominique, Molly and Lucy were fighting over who got to be Gwen's best friend. So it was a good day. But not for long. As Gwen contacted Mary-Sue headquarters, she knew the world domination plan was almost completed.
Their mission: to replace every canon character with a Mary-Sue or Gary Stu, until the universe was filled with annoyingly perfect people who ruin every media franchise. Good plan? They thought so.
"Freeze!"
Two teenagers, who looked very familiar appeared out of nowhere. The boy slapped handcuffs on her wrists.
Gwen studied the girl. "Mum!" she cried, horrified.
Hermione screamed. "I have a Mary-Sue as a daughter? Harry, quick, we have to get rid of her!" she pointed her wand at Gwendolyn and muttered a few words.
Poof!
They duo sighed. "She was probably the creation of another Dramione lover, who gave me another child," Hermione said, immensely relieved.
Harry patted the witch's shoulder very sympathetically.
"Don't worry, Harry. We'll meet one of your Mary-Sue kids soon enough. Maybe a Drarry lover created him/her. That would be exciting. And weird."
Harry shuddered. No other words were necessary.
