For the record, I believe the perfect Hagaren crossover would be with Discworld. It would be, for lack of a better word, boss.
TITLE: In Control (me + titles = suck)
AUTHOR: Forensic Ninja
WARNING: Some swearing
GENRE: Humour, crossover/fusion, gen
SUMMARY: “Colonel,” Lupin said, holding out the phone as if it were a particularly nasty document, “I believe Lt. Colonel Potter is on the phone, sir.”
NOTES: This is a fusion between Harry Potter and Fullmetal Alchemist, in which HP characters have taken the role of FMA characters. I have tried to keep them as in character as possible for a fusion fic. This all meant in good humour and because this idea wouldn't take "no" for an answer.
Also: the Theodore mentioned is supposed to be Theodore Nott
WORD COUNT: 900 (whee)
