1.)
Reset! - Young Justice fanfic. Basically, how Bart/Impulse SHOULD have matured, and how the relationship dynamics should have remained between he and so many people who were important to him. The author remembers little details from the Impulse and YJ series and weaves them into the story.
2.)
Exile - Avatar: The Last Airbender fanfic. Deals with a lot of dangling plot points regarding Zuko's mother and what exactly was going on, and why Iroh didn't contest Ozai's seizing the throne.
3.)
Veritas - I can't provide a direct link to this fic, as it's not fully compiled yet, but if you search for that title on the boards, you'll find it. A Lois and Clark (TV series from the '90's) fanfiction that is obviously AU, but interesting. What would Superman do in our world?
4.)
All That This Entails - Pride and Prejudice fic. Yes, I'm terrible. I don't care. What would happen if the lives of the Bennets were changed after Elizabeth's embarrassing stay in Kent?
Those are really all I have offhand right now, but I enjoyed reading them all. Only Veritas is finished, however, as a note for those of you who hate unfinished fics. All are, however, being worked on.
