Crossover D/M Fic (Doctor Who/Harry Potter)

[narwhale-callin.livejournal.com]

Okay, you guys. I know with nine hundred percent certainty that this idea has been done before and is probably lame. But gosh darn it, for some reason I can't actually find it and I wanted to give it a go myself. Remember to HEED THE WARNINGS.
 
Also, I'm not exactly sure how kosher crossover fics on this comm are?  I promise this one is basically purely Doctor/Master, the focus is Doctor/Master, and the result is Doctor/Master, but if for whatever reason this is somehow Not Kosher to Comm, let me know, and I will make it vanish forever.

Title: One of Mine
Pairings: Simm!Master/Barty Crouch, Jr (Tenth Doctor), Future!Master/Barty Crouch, Jr (Tenth Doctor)
Rating: R
Word Count: 4,293
Summary: Two evil geniuses meet each other. What could possibly go wrong?
Warnings: Violence, gore, character death(s), spoilers for Harry Potter and the Goblet of Fire and Doctor Who's The End of Time. Basically, if you're someone who covers your eyes during surgical scenes on medical shows, you might want to back away slowly.
Disclaimer: BBC owns Doctor Who and all of its characters, not I. J.K. Rowling owns all of her characters and the Harry Potter world, not I. Please don't hurt me for writing things I don't make any sort of profit from.

Please don't hurt me.  Please don't hurt me.

Go, evil Doctor!  Go!

EDIT:  A big, big thanks to edzel2 for giving me a new and much improved title that isn't so deceptively fun-sounding!
