Hey, everybody! I'm back with another challenge. I reached watched the Fourth Shinobi World War arc, and an interesting idea came to me. Of course, this is another Fullmetal Alchemist/Naruto challenge, but a little different.

What would happen if an Uchiha female OC stumbles in the world of FMA and develops amnesia?

Now for some quick guidelines and rules:

1) The character is pretty young I'll say about five or six.

2) I want the character to eventually unlock her Sharingan, then later, her Mangekyou Sharingan. By what means, it's up to you. But everyone knows the Sharingan unlocks by 'the loss of love'.

3) This more like part two of number 2… Anyway, with the whole 'Curse of Hatred' the character is definitely going to develop over time, it would be cool if the character completely turns into a villain protagonist over the course of the story. I've never seen an OC as a villain protagonist before, especially ones that were friends with Edward, Alphonse, and Winry before turning all evil. I guess, watching Hashirama's interactions with Madara and Naruto's with Sasuke got me into all the 'Uchiha former friend turned evil'. I just thought it would be nice if Ed, Al, and Winry got the same dynamic from their own mysterious Uchiha friend. If a villain protagonist isn't up your alley, a plain anti-heroine is fine.

4) When it comes to her abilities, I think the OC's strongest point would be mind manipulation. You know, brainwashing her victims, mind screws, mind games, all that jazz. I think they ability to manipulate people to get them to do what you want, even die for you make the best villains.

5) NO HAREMS!

6) Pairings? Either Ed/OC or Al/OC or no pairings at all. Most likely a gen fic (no pairings).

I think that's really it. I just realized not one has done a Naruto/FMA crossover story focusing on an Uchiha, and I thought this would be fun for someone to write. Especially, if the character eventually turns from good to evil, due to their 'Curse of Hatred'. Probably why didn't want any canon characters and just settled for an OC.

I always thought this would make a great drama/psychological thriller/crime story, if written well. It has that potential. A chess master villain protagonist, lots of suspense/plot twists, mind screws, etcs.

Anyway, who's up to the challenge?
