So, this fic was apparently purged from ff.net a few years back due to its title containing a curse word (though it's totally not one), and I only recently discovered that. I'm reposting it there with a censored title, but I figured I'd repost it here, too.

Moonlight illuminated the scene at the edge of the Forbidden Forest as well as the sun ever did.
It shined down on two boys, aged nearly fourteen, circling one another and snarling.
“I knew I’d catch you here!,” yelled the first boy. “And now I’m gonna tell! They’ll expel you for sure!”
The second boy scoffed. “They’ll know you were here, too, nit-wit!”
“So? I’ll just say I was doing my duty to the school! They’ll probably make me prefect! My father is on the board! They won’t kick me out! I have a place here. Unlike you, you blue-haired freak!”
In an instant, the blue hair in question changed to a fiery orange and its owner launched himself at his enemy. He landed a punch to the other boy’s nose before his smallish size and not-yet-developed muscles landed him in trouble. The other boy was larger and stronger by a lot, and as he ground the attacking boy’s face into the dirt, he laughed.
“Oh! Maybe I won’t turn you in, after all! This is too much fun! I wouldn’t have my favorite punching bag if you left, freak!”
As rocks ground into the beaten boy’s face and a trickle of blood ran from his nose, he said nothing. He’d been in this position many times before. He knew he could do nothing but wait for his release.
Eventually, it came, as it always did. His tormentor grew tired of him and stormed off to the castle, throwing several good insults over his shoulder as he did so.
The smaller boy watched him go with hate in his eyes, and as his hair morphed past orange to a bright scarlet, Teddy Lupin wished, not for the first time, that he’d inherited his father’s special condition instead of his mother’s.
